Figure 16 shows the Kendeng mountains defining the caldera's arcuate topographic margin bounding the N (with elevations up to 1,559 m). Kawah Ijen, the active vent of the complex, is known for hydrothermal and phreatic behavior in its crater lake. Im Vorfeld hatten wir bereits mit unserem Guide, den Freunde uns empfohlen haben, den Treffpunkt und die Uhrzeit vereinbart. Many other post-caldera cones and craters are located within the caldera or along its rim. Würde auch gerne etwas zu den nötigen Vorbereitungen und dem Guide erfahren . The left-hand column shows time intervals; the other columns indicate the number of earthquakes or maximum tremor amplitudes seen during the time intervals. Maximum tremor amplitude was 1-6 mm until 22 August when tremor was no longer continuous and maximum amplitude decreased to 1 mm. The next day, 37 shallow volcanic earthquakes were detected. Wenn der Vater Schwefel abbaut, ist seit der Kindheit klar, dass der Sohn diesen Job auch machen wird. Three phreatic eruptions occurred from the center of the crater lake in early July, but caused no damage. The number of volcanic earthquakes increased until 1 July when a gradual decrease began. Phreatic eruptions occurred in 1796, 1917, 1936, 1950, 1952, 1993, 1994, 1999, 2000, 2001, and 2002. Sujanto, Syarifuddin M Z, Sitorus K, 1988. The highest measured temperature of the solfatara was 224°C, while the CO2 content of the atmosphere near the lake surface was normal, ~300 ppm. The studies were small (30 miners) and for comparison (control groups) used similar numbers of residents who lived around the mine but did not work as miners. Clicking on the small images will load the full 300 dpi map. Gas plumes emitted from the crater rose up to 150 m high during October. van Bemmelen R W, 1941. Kawah Ijen is a basaltic-andesite to dacitic stratovolcano located in the Banyuwangi Regency of East Java. Lake level was approximately 10 cm higher, water temperature at the foot of the fumaroles was 37-39°C and pH and electrical conductivity (EC) were -0.01 and 312.6 mS/cm, respectively. Auf dem sandigen Boden muss man aber vorsichtig sein, um nicht wegzurutschen. Maps, hazards, and Ijen's Merapi. During this time and through 13 May, the amplitude and number of earthquakes gradually decreased and the crater lake water temperature decreased by 8°C. | December Seismicity at Ijen during 9 December 2002-26 January 2003. By the end of September, the plume reached up to ~100 m above the summit. Neither volcano was erupting, but the caldera lake in Kawah Ijen and the devegetated caldera and summit region at Raung were obvious features. Measurements of temperature and pH were made every morning during 14-19 August at four locations: the Banyupuhit River, ~ 5 km from the Banyupuhit River source, the acid lake in the summit crater, and the E shore of the crater lake. This revealed that the actual source of the river is a set of springs about halfway along this transect (figure 10), with the water emerging from a cliff on the E flank of the valley from between two lava flows. There is no Deformation History data available for Ijen. Shallow volcanic earthquakes showed the greatest increase. But the catch is, it’s only visible at night! This video is unavailable. One is the cone located to Raung's NE, Soeket (Suket) stratovolcano (2,950 m). The largest concentration of post-caldera cones forms an E-W-trending zone across the southern side of the caldera. One small explosion occurred on 29 July, accompanying an increase in the number of B-type earthquakes (table 4).

Alle wichtigen Infos für deine Reise in Indonesien findest du in dem Beitrag „Alle Tipps für deine Reise nach Indonesien„. Decreased seismicity; fires detected on satellite imagery. Try carrying 200 kilos through a cloud of sulfur down the side of a volcano. During 9 September through at least 8 December 2002 at Ijen, activity was above background levels. This increase, however, was not followed by phreatic eruptions as in 1993 (BGVN 18:07 and 19:05). Table 8. CVGHM raised the Alert Level for Ijen from 2 to 3 (on a scale of 1-4) on 12 March because of increased seismicity and visual observations. In their research in the Ijen Banyuwangi Crater, they discussed the geological and volcanological history of Mount Ijen, the characteristics of the Ijen eruption over the past 200 years, and the chemical composition of the Ijen Crater lake. Activity included heightened continuous tremor, shallow volcanic (B-type) earthquakes, and one small explosion earthquake (table 2). Bezahlt werden die Schwefelarbeiter pro Kilo Schwefel, allerdings sehr schlecht (900 indonesische Rupiah, also ein paar Cent pro Kilo). Aber unser Guide hat uns super viel Zeit gelassen und einiges erzählen können. 2011: July Das Wort Klettern passt hier wohl am besten, denn der Weg in den Krater des Ijen Vulkan besteht hauptsächlich aus Steinen und Felsen. Conductivity determinations were made of acid lake waters sampled on 7 December 1998 (BGVN 23:11) by Bardintzeff, Marlin, and Barsuglia. Wäre super nett, wenn du uns zukommen lassen kannst, welchen Guide du hattest, da wir uns auf den dann gut verlassen könnten. 1 October-15 December 2011 activity. Wenn du eine Tour im Voraus (z.B. Information Contacts: Dali Ahmad, Hetty Triastuty, Nia Haerani, and Suswati, Vulcanological Survey of Indonesia (VSI), Jalan Diponegoro No. November 2003:Tremor, type-A volcanic earthquakes; felt earthquake (MM III). A digital elevation map was prepared (using digital photogrammetric mapping methods) to provide the spatial framework required for interpretation of the geophysical surveys. Wir waren zu zweit mit unserem Guide, dadurch konnten wir unser Tempo bestimmen und Pause machen, wenn wir eine brauchten. No accurate measurements were made until summer 2008. The area near the E shore appeared lighter than the rest of the lake, probably due to a spring at the bottom of the inner E slope. He noted that on 29 June the summit area was closed to public access after birds were seen falling into the water. Dies ist auch ein Punkt, den man bedenken sollte. Watch Queue Queue Based on this very limited survey, the flux of SO2 was estimated to be 330 t/d. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. Kawah Ijen covers part of the eastern margin. – Do’s and Dont’s in Indonesien . IAVCEI, 1973-80.

Falls du noch nicht dagewesen bist – Scooter leihen für 5€ und selbst hinfahren mit Google maps. VSI reported that during 28 January-3 February there was an increase in seismicity at Ijen in comparison to the previous week. An infrared Space Shuttle photograph (figure 1) taken in May 1992 showed clear views of both Raung and the Ijen volcanic complex. 2014: August This resulted in closing the area to visitors. lake [12]. Tijdschrift voor Indische Taal-, Land- en Volkenkunde, Deel 7, 265–286. Im Jahr 1976 erstickten dort 49 von insgesamt 50 Gasarbeitern. Du kannst die Kommentar-Benachrichtigung auch ohne eigenes Kommentar abonnieren. The first eruption recorded by western observers goes back to 1796, and the most recent was in 2018. Malang Indonesien: Tipps für das bunte (und blaue)... Lombok Sehenswürdigkeiten: Die 15 beliebtesten Orte. | May 2002: February Ijen Caldera encloses a group of small stratovolcanoes. The eruption displaced the crater lake and resulted in inundation of several villages along the drainage route. Between 2006 and 2007, a significant decrease of the SP anomalies (~ 120 mV) on the N and E crater rim was observed. Scientists from Simon Fraser and McGill universities conducted preliminary geophysical and geochemical field studies at Ijen (figure 4) between 13 and 26 August 2006. Manchmal zahlen wir gerne ein paar Euro mehr, wenn wir dafür etwas an das Land zurückgeben können. During May, a thin-white plume reached to ~50 m above the summit. 57, Bandung 40122, Indonesia (URL: http://www.vsi.esdm.go.id/). [Correction: the Alert Level remained at 3.]. The main SP/elevation gradient is between -0.31 and -0.56 mV/m with a higher SP average than on the E rim (-4 mV in the S versus -70 mV in the E). Wir waren sehr zufrieden. The number of shallow volcanic earthquakes decreased in comparison to the previous week. We welcome users to tell us if they see incorrect information or other problems with the maps; please use the Contact GVP link at the bottom of the page to send us email. Phreatic eruptions have been … This team again conducted fieldwork at Ijen during 18 July-7 August 2008. was für einen Guide hattet ihr für die Besteigung des Ijen? In Rohren kühlt der gasförmige Schwefel ab. Lade uns auf einen Bali Kopi ein, damit wir genügend Energie für den nächsten hilfreichen Artikel für dich und all die anderen reisefreudigen Menschen da draußen haben! Wäre super wenn du mir die Infos geben könntest fliegen in ca 2 Wochen nach Bali! Temperature (°C) of gases measured at ~ 50 cm depth in pipes and fumaroles using a K-type thermocouple. The lake water temperature at a depth of 5 m also rose from 42.7 to 44.7 degrees Celsius on 3 and 17 March, respectively. The wind speed (measured by handheld anemometer at plume height) during this time averaged 6.1 m/s and the resultant SO2 flux was therefore calculated to average 412 metric tons per day (t/d) with a standard deviation of 154 t/d. The biggest anomaly occurred on 19 October 2002 close to Kawah Ijen, the only currently known locus of activity in the complex. Crater lake water temperature through most of August was 39-41°C, and the pH was 1. The Alert Level remained at 2 (on a scale of 1-4). Once the liquid cools and hardens, workers break the solid sulfur into large pieces and load it into baskets for manual transport out of the crater. Table 2. On 12 July, the average gas concentration was similar, ranging between 1,600 and 3,000 ppm-m. Information Contacts: Dali Ahmad, Volcanological Survey of Indonesia (VSI) (URL: http://www.vsi.esdm.go.id/). The lowest point of the caldera's N rim (~850 m) occurs near Blawan village at the breach in the caldera wall. One deep volcanic earthquake was registered during 13-19 January. Achtung: Die Zeit wird auf Java umgestellt! Der Kratersee (Kawah Ijen) wird von Experten als das größte Säurefass der Welt bezeichnet. Five episodes of tremor were reported. 2007 field visit found degassing and increasing fumarole temperatures. Und bevor du dich an den genauso anstrengenden Abstieg machst: Genieße den überwältigenden Ausblick und einmaligen Moment auf 2800 Meter. The East Java volcano is the scene of sulfur mining and a highly acidic lake. Based on increased seismicity, visual observations, and lake water temperature increases, CVGHM raised the Alert Level from 1 to 2 (on a scale of 1-4). In the next few months, scientists documented four periods of significant unrest. 52, Fall Meet. Ijen remained at Alert Level 2. One area was flat in 2007, but sub-vertical in 2008, indicating an uplift of approximately 1 m. Uplift was also apparent in other areas, but could not be quantified. 07/1989 (SEAN 14:07) High-pressure steam emission, but little seismicity, 03/1991 (BGVN 16:03) Slight increase in crater lake temperature; tremor episodes, 04/1991 (BGVN 16:04) Crater lake changes from gray and bubbling to light green, 05/1992 (NASA STS 49) Infrared Space Shuttle photograph shows caldera and crater lake, 07/1993 (BGVN 18:07) Phreatic eruptions from the crater lake, 05/1994 (BGVN 19:05) Additional details about July-August 1993 phreatic activity, 07/1994 (BGVN 19:07) Minor phreatic eruption in February described, 06/1997 (BGVN 22:06) Late-June interval of increased seismicity; lake color changes, 08/1997 (BGVN 22:08) Elevated seismicity during 27 June-11 July; lake-color shifts and odors, 11/1998 (BGVN 23:11) Recent measurements of acid crater lake, 07/1999 (BGVN 24:07) Two phreatic eruptions at the active crater lake on 28 June, 09/1999 (BGVN 24:09) Increased seismicity since April 1999; white plumes and phreatic eruptions, 10/2000 (BGVN 25:10) Low-medium density ash emission; elevated seismicity with continuous tremor, 09/2001 (BGVN 26:09) Heightened seismicity through at least September 2001, white-gray plume to ~100 m, 12/2001 (BGVN 26:12) Higher-than-normal seismic activity from October 2001 through at least 6 January 2002, 04/2002 (BGVN 27:04) Continuous tremor, volcanic and tectonic earthquakes through April 2002, 08/2002 (BGVN 27:08) Small explosion in late July 2002 accompanies increased seismicity; ash emissions, 11/2002 (BGVN 27:11) Above-background seismicity through at least 8 December 2002, 03/2003 (BGVN 28:03) Decreased seismicity; fires detected on satellite imagery, 10/2003 (BGVN 28:10) Shallow volcanic earthquakes and continuous tremor recorded in October, 12/2003 (BGVN 28:12) November 2003:Tremor, type-A volcanic earthquakes; felt earthquake (MM III), 11/2004 (BGVN 29:11) News report cites increased activity beginning on 17 June 2004, 02/2007 (BGVN 32:02) Acidic crater lake and active solfatara investigations, 09/2007 (BGVN 32:09) 2007 field visit found degassing and increasing fumarole temperatures, 02/2009 (BGVN 34:02) Visual, geochemical, and geophysical observations during mid-2008, 12/2011 (BGVN 36:12) Sharp increase in seismicity in December 2011 spurs evacuation preparations, 07/2012 (BGVN 37:07) 2012 high seismicity, blasts, and subaqueous emissions; maps of complex, High-pressure steam emission, but little seismicity. The blasts sent plumes rising to 50-100 m over the summit, and registered seismically as follows: 1-7 July, 8 blasts; 8-14 July, 12; 15-21 July, 40; and 22-24 July, 32. Information Contacts: Volcanological Survey of Indonesia (VSI), Jalan Diponegoro No. As in 2006 (BGVN 32:02), SP surveys were conducted on the summit rim and also down the S flank to the intersection of the Banyupuhit river (dashed line, figure 8) and the main road. Because of the increasing activity, VSI warned residents, tourists, and sulfur miners that the crater area was closed until early August 1997. Tremor became discontinuous by the end of October, and elevated seismicity continued. During this reporting interval an intrusion appears to have risen to a shallow depth beneath the crater lake. 1/2, p. 14. Alle During this period, volcanic activity was restricted to persistent degassing of the solfatara (sulfurous fumarole) located on a small dome in the SE part of the crater (figure 7). As seen on a relief map (figure 16), Merapi (on the far E side of the caldera) forms the highest point in the complex, 2,799 m (and reflects the summit elevation value we typically provide for the complex). Congruent with that interpretation, sulfurous-gas emissions measured just over the lake surface were very high at the time. A coincidence of low wages and a small local demand for native sulfur supports artisanal mining at These variations also corresponded to changes in the weather. At Ijen these changes are attributed to underground and surface water. Er war früher selber einmal Schwefel-Träger. This report discusses their findings. Nearly 70 thousand metric tons of sulfur are produced by these methods. Throughout the report period, a "white-thin ash plume" [steam plume] was reported to rise 50-100 m above the volcano. Immediately west of Gunung Merapi is the renowned historically active Kawah Ijen volcano, which contains a nearly 1-km-wide, turquoise-colored, acid crater lake. Dieses Spektakel wollten wir aus dem Nahen betrachten und wir sind den steinigen Weg in der Dunkelheit nach unten geklettert. Distinct variations in fumarole temperature observed during the course of the field campaign linked closely to weather conditions. EMPFEHLUNG : Nehmt, wenn ihr den Schwefel-Arbeitern, etwas Gutes tun wollt, ein paar kleine Flaschen Wasser, Gebäck oder eine Schachtel Zigaretten mit und verteilt sie an die Arbeiter im Krater. Due to the explosive eruption style of this stratovolcano, eruptions can be very dangerous because the lake will drain to form devastating lahars. Shallow volcanic and tectonic earthquakes were recorded (table 3). Kawah Ijen harbours a large warm acidic crater lake and an active sulphur mine. van Bergen and others (2000) made the following remarks: "The lake chemistry is determined by dissolution of magmatic volatiles, fluid-rock interaction, evaporation of the lake water, dilution by meteoric water and recycling of lake water through seepage into the subsurface hydrothermal system. The 2006 SP survey suggested that the S and W flanks of the crater were characterized by a hydrothermal system; however, this year's SP and temperature study shows greater complexity. During 23-29 April seismic activity was higher than normal at Ijen, with a high number of shallow volcanic earthquakes (nine). Bis zum Gipfel sind es ca 3 h oder? Huhu Marco, am besten du übernachtest in einem Homestay in Banyuwangi (siehe Empfehlungen weiter oben) und lässt dir dort einen Guide organisieren. The Ijen Caldera was clearly defined, along with some post-caldera cones on its southern margin (Kawah Ijen and Gunung Merapi, Gunung Rante, and Gunung Pendil). Guide brauch man auch auf dem Berg nicht, das ist alles einfach zu finden. Palmerah Barat 142-143, Jakarta 10270 (URL: http://www.thejakartapost.com/). Thermal anomalies were detected by MODIS throughout 2001 and 2002 adjacent to the Ijen (Kendeng) caldera. Today, most of the world’s sulfur is produced as a byproduct of oil refining and natural gas processing. The Alert Level was lowered to 2 (on a scale of 1-4) on 13 May. Meine fragen sind wie viel hat es gekostet?was ost alles beinhaltet und wie lange ging diese tour? Processing of the SP data along the crater profile by continuous wavelet transform (Mauri and others, 2006) shows that the hydrothermal fluid cells are near the surface (less than 200 m below the topographic surface) suggesting that the hydrothermal system is under high pressure with significant heat flux, as shown by the solfatara. . During the period of 18 May through the week ending on 21 June a "white ash plume" rose 50-100 m. Recorded tremor had an amplitude of 0.5-3 mm. More than 60 explosive eruptions - mainly with VEI = 2 - have been reported to have occurred on Bromo over the past four centuries. Kawah Ijen volcano, East Java - blue sulfur flames (16 Images) Ijen volcano: crater lake & sulphur mining (32 Images) More on VolcanoDiscovery. VSI stated that earlier, during 2-8 July, seismic and explosive activity had increased and the Alert Level had been raised from 1 to 2 (on a scale of 1-4). That and many other web sites show photos of the mining process. Jene Links und Partner ermöglichen die Aufrechterhaltung des Blogs. According to the sulfur miners, these fumaroles appeared at the end of summer 2007. Ijen has erupted six times since 1796, most recently in 1993. Acidic crater lake and active solfatara investigations. Continuous tremor, volcanic and tectonic earthquakes through April 2002. During 9 December 2002-26 January 2003, the Volcanological Survey of Indonesia (VSI) reported that seismicity at Ijen was dominated by shallow volcanic and tectonic earthquakes (table 6). The north caldera wall forms a prominent arcuate ridge, but elsewhere the caldera rim is buried by post-caldera volcanoes, including Gunung Merapi, which forms the high point of the complex. – Der perfekte Reiserucksack This trend cannot be explained by mixing of the gases with various amounts of atmosphere because nitrogen contents in the gas phase do not correlate. Seismicity registered at Ijen, 27 October-30 November 2003. Third, no significant deformation was observed since 2006 on the summit of Kawah Ijen. The crater lake's water was brownish-white and had sulfur agglutinate floating on the surface. PVMBG reported that on 29 May a gas explosion at Ijen generated a plume that rose 250-500 m above the surface of the lake. ... more According to news articles two sulfur miners heard the explosion from under the water at 12:30 local time, which created 3 m high waves in the lake. 3/4, p. 8-12. Mapping along this transect revealed a thick sequence of phreatic, phreatomagmatic, and lahar deposits, as well as three distinct lava flows. Bist Du sicher dass die rote Lavawolke die Du gesehen hast war vom Bromo war? References. Very small-scale maps (such as world maps) are not included. van Bergen, M.J., Bernard, A., Sumarti, S., Sriwana, T., and Sitorus, K., 2000, Crater lakes of Java: Dieng, Kelud and Ijen, Excursion Guidebook, IAVCEI General Assembly, Bali 2000, 43 p. van Hinsberg, V., Berlo, K., and van Bergen, M.J., 2010, Extreme alteration by hyperacidic brines at Kawah Ijen volcano, East Java, Indonesia: I.

Die Bewohner von Banyuwangi, wo die meisten Schwefelarbeiter wohnen, suchen sich diesen Beruf nicht aus. About 5,000 people live within 10 km of the lake but farther away, many thousands more would be at risk in the event of large lahars. Topogr. Journal 28, p. 243- 262. Fälschlicherweise wird es manchmal als blaue Lava bezeichnet. Ijen's characteristics and history Ijen's characteristics and history A play of colors and a game of aromas in a surprising volcanic setting. Pro Person 750.000 Rupiah. Der Eigentümer ist ein super Typ, der einem viel über Land und Leute erzählen kann und er organisiert auch Guides für seine Gäste. During the period from 8 to 31 July, seismicity was variable, but there were no phreatic eruptions. Just N of Pendil Djampit lies a fault with offset down towards the caldera (figure 17). Historical. Das Puri Amalia Guesthouse in Banyuwangi ist zwar sehr einfach, aber dafür arbeiten hier super liebe Menschen, es gibt ein leckeres Frühstück und das Team hilft dir bei deiner Besteigung auf den Ijen (auf booking.com ansehen), Der Eigentümer des Osing Vacation Homestay in Banyuwangi ist ein super Typ, der dir einen sehr günstigen Ijen-Guide organisieren kann. They also wrote about the crater lake overflowing river merging into the Banyupahit river which was used as irrigation for 3,500 hectares of agricultural land and consumed … Sources: Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG, also known as CVGHM), Inibaru, 2012 high seismicity, blasts, and subaqueous emissions; maps of complex. Thisarticlewillfirstbrieflydescribethevolcanic settin The path from Paltuding (SW base) to the top of the crater was closed as a result. Near the S side it was 140 and only 98-120 mS/cm near the hot sub-lacustrine spring. In der Nacht kann es auf dem Ijen relativ kalt werden. According to news articles two sulfur miners heard the explosion from under the water at 1230, which created 3-m-high waves in the lake; the miners ran but one tripped and fell into the lake. During 30 January to 5 February, seismic activity increased at Ijen volcano. Recent dental studies cited in this subsection compared the teeth and gums of laborers to residents living nearby who endured less exposure to the volcanic gases. Most of the eruptions were phreatic. Approximately 100 miners extract sulfur, removing it from the crater in two trips each day, and carrying on average 60-80 kg of sulfur per trip. The Ijen complex resides at the E end of Java just across the strait from Bali (figure 13, inset map). First, Kawah Ijen hosts a large and deep lake (~30 x 106 m3) (Takano and others, 2004), whose surface level changes over the years. 2013: August Water temperature in the crater lake on 2 July was normal (36°C). Eruptions Der älteste Schwefelarbeiter, der immer noch täglich einmal auf den Vulkan steigt, ist über 70 Jahre alt. On clear, wind-free days, fumarole temperatures were highest. On 24 March, CVGHM reported that Ijen's lake water chemistry changed during 10 January-17 March, exhibiting a significant increase in carbon dioxide, especially after 5 February, and an increase in acidity. Lake temperatures varied between 31 and 43°C and the pH was -0.02. was habt ihr denn für eure Tour gezahlt und was hat das alles beinhaltet (Gasmasken, Taschenlampe…)? White gas emissions rose 50-150 m from the crater, and a earthquake was felt on 4 November of Modified Mercali intensity III. The lake water temperature was 26.8 and 34.2 degrees Celsius on 8 and 14 December, respectively. Visual observation revealed no change in the crater lake level or fumarole activity compared to observations (BGVN 32:02) at roughly the same time last year (dry season). Um ein Uhr morgens wurden wir von unserem Guide und einem Fahrer an unserem Hotel abgeholt. Indonesia. Picturesque Kawah Ijen is the world's largest highly acidic lake and is the site of a labor-intensive sulfur mining operation in which sulfur-laden baskets are hand-carried from the crater floor. Only 16 shallow volcanic earthquakes were recorded the following week, along with continuous tremor (0.5-2 mm amplitude). During the first survey (conducted over a 2-hour period), the concentration-pathlength of the gas in the plume fluctuated between 1,000 and 2,500 ppm-m. Summary of seismicity at Ijen, 30 January-30 September 2001. Hey, During this period, volcanic activity was low and restricted to persistent degassing of the solfatara in the SE part of the crater. Wir sind etwa anderthalb Stunden die drei Kilometer zum oberen Kraterrand gelaufen. About 5,000 people live within 10 km of the lake but farther away, many thousands more would be at risk in the event of large lahars. Kawah Ijen is an extremely rare volcano that actually erupts electric blue flames from its crater. Other details regarding the eruption remain undisclosed. Das Wasser ist schwefelhaltig und zeigt, wie aktiv der Vulkan ist. The volcano is at Alert Level 2 (on a scale of 1-4). This almost certainly represents the inflow of meteoric water and groundwater. – Reisekrankenversicherung. High-pressure steam was emitted from the solfatara fields near the lake. Wenn du eine Tour im Voraus von Bali aus buchst, wird es um einiges teurer! Wir möchten gerne im September Indonesien erkundigen. The Alert Level remained at 1 (on a scale of 1-4), and residents and visitors were advised to not approach the crater rim or descend to the crater floor. Due to its easy accessibility, turqoise lake and unique sulphur mining operation, the crater is regularly visited by tourists. Courtesy of the Volcanological Survey of Indonesia (VSI). A white, variable-density ash plume rose 25 m above Ijen's summit. Visual observations were not available for late September and parts of October because of inclement weather. The Alert Level remained at 2 during the report period. The following week, the ash emission changed to a low-density plume and rose 25 m. In late September, seismographs registered an increase in shallow volcanic (B-type) earthquakes and the initiation of continuous tremor. A lot of rain in the past few months increased the volume of the lake, possibly contributing to a disruption in the system, though these seasonal changes were within normal ranges at the volcano. In comparison to 2007, the fumarole mound of Kawah Ijen had changed substantially. Vielen Dank. The Jakarta Post reported that the National Disaster Mitigation Agency (Badan Nasional Penanggulangan Bencana, BNPB) had prepared 466 million Indonesian Rupiah (US$51,260) in disaster-relief funds for the basic needs of evacuees for a two week period in the case that an evacuation occurred. Geophysical changes, summer 2006-2008. Etna Discovery 25 May - 1 June. | March Measured temperatures of the crater lake waters were mostly stable during October (ranging from 30.6-31.2°C), but showed significant variation and increased maximum temperatures during November and December 2011 (figure 12b). A transect along the Banyu Pahit river (see map, below) from the dam to the bridge at Watu Capil, revealed that the water was a few degrees above ambient where it emerged, but was close to the air temperature from 500 m downstream. Two phreatic eruptions occurred at the Sibanteng location inside the active crater lake at 0510 on 28 June. Self-potential surveys.
