The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Small eruptions from Marapi in western Sumatra (image: PVMBG via detiknews)
Two eruptions occurred from the volcano yesterday (4 June 17) at around 11:00 local time, producing small ash plumes that rose a few hundred meters. ...more
The volcano remains at alert level 2 ("waspada") on a scale of 1-4 and an exclusion zone of 3 km around the summit is in place. The nature of the eruptions is unknown without further analysis of the ash, but could be phreatic (steam-driven). Similar small explosive eruptions have been occurring sporadically during the past years. Whether the volcano is entering a phase of increased activity is impossible to predict. [less]
The volcano erupted again yesterday afternoon at 16:15 local time, the volcano observatory post reported. It appears it was one of the largest explosions during the volcano's current phase of activity. ...more
Although the eruption was itself not visible due to cloud cover, the seismic signal showed a strong explosion that lasted 38 seconds and relatively "thick" ash fall occurred shortly afterwards in Batipuh and Tanahdatar districts until 17:45. The alert level of Marapi remains unchanged at level II out of 4. Authorities recommend people to avoid a 3 km radius zone around the volcano. [less]
Another ash eruption occurred at the volcano this afternoon at 16:15 local time. According to local news quoting the local VSI volcano observatory spokesman, the eruption today was the largest in a series since the alert status had been raised on 3 August last year. Ash fell in a radius of 3 km where some villages are located. ...more
Also according to the article, the volcano has had a total of 57 recorded eruptions since January 2014. Since all of these have been small, and Indonesia is very used to small volcanic eruptions, they hardly make any news at all (while such an event at other volcanoes would). The alert status remains unchanged at 2 out of 4. [less]
Ash emission from Marapi volcano on Sumatra (ANTARA/Muhammad Arif Pribadi/rj)
New ash emissions occurred from the volcano's summit crater this morning at 10am local time, Antara News reported. The eruption , back into eruption. Similar small eruptions have been observed during the past years and the current status of the volcano remains at level 2 (out of 4). ...more
Climbers are advised not to approach the crater to within 3 km radius because similar (probably phreatic) explosions can occur with little warning. [less]
The volcano (not to be confused with MErapi in Central Java) erupted again yesterday (Thu) morning, producing a series of small (probably phreatic?) ash explosions, with ash plumes that rose to a few 100 m above the crater. ...more
According to local newspapers citing PVMBG, the new eruptions were preceded by an increase in seismic activity under the volcano since 1 Januaryt and there were 5 explosions at 05:34, 05:53, 05:59, 06:12 and at 07:14 am local time, as well as some weaker ash emissions at 08:07. The current alert status of Mount Marapi, a popular climbing destination, still stays at level 2 (out of 4), but it is recommended not to approach the crater within a radius of 3 km. [less]
Another small ash eruption occurred yesterday morning 10:10 am local time, the Jakarta Post wrote. According to the article, the explosion produced a small ash plume rising 350 m. VSI maintains the volcano on unchanged alert level 2 (out of 4, "Waspada", "alert").
A small eruption occurred this morning (9 am local time), producing an ash plume that rose about 350 m according to local news. ...more
Marapi has been showing increased activity since August 2011. VSI keeps the volcano at level 2 alert (out of 4) and recommends not to approach the summit within a radius of 3 km, as stronger eruptions could occur any time. [less]
The volcano continues to produce small explosions every now and then. Local press reported two small eruptions this morning. ...more
The first one occurred at 7:49 am (local time WIB), producing an ash plume of 300 meters height, and the second at 8:32 am with an ash plume rising 600 meters. The alert status had previously been raised from Normal to Alert (level 1 to 2) on 3 August and an exclusion zone of 3 km radius around the crater is in place. [less]
A small explosive eruption occurred this morning at around 08:05 local time, generating a small ash plume rising a few hundred meters above the crater. Marapi volcano, one of Sumatra's most active, has been producing intermittent explosions with ash plumes up to 1 km high frequently since August 2011. ...more
For Indonesian standards, this is no big activity, and Indonesia's Volcanological Survey maintains alert level II only. [less]
Mount Marapi volcano in West Sumatra had new ash emissions today, a local newspaper reported. "Smoke" (=volcanic ash) was seen being emitted from the summit crater between 8-9 am local time this morning and produced a plume rising about 300 m. ...more
The newspaper notes that since Marapi had become active again on 3 Aug 2011, ash emissions have been occurring almost daily. The Center for Volcanology and Geological Hazard Mitigation (PVMBG) maintains level II alert status (out of 4) for the volcano. [less]
Marapi volcano had a modest eruption this evening (26 Sep) between 16:30-18:15 h local time. (Note Mapari is in Sumatra and different from frequently active M-E-rapi volcano near Yogyakarta in Central Java). ...more
The eruption, probably the largest in this year so far, produced an ash column rising 1.5-2 km above the crater and was accompanied by load roaring noises, local media reported. Increased activity had been noticed since 3 August. A 3 km exclusion zone was placed around the volcano and hikers are advised not to climb to the summit... PVMBG has not changed the alert status of the volcano (yet). [less]
A small ash eruption was reported from Marapi volcano in West Sumatra near the cities of Bukittinggi, Padang Panjang and Batusangkar at 07:15 local time on 18 May. The eruption lasted about 10 minutes, and produced an ash plume that rose 600 m.
Mount Marapi in West Sumatra continues to produce ash explosions during the past week. According to local news, a few weak explosions on Wednesday were followed by an eruption on Sunday morning produced an ash column about 1 km high, which traveled about 10 km southwards. The volcano is currently closed for climbers and a 3 km exclusion zone is in place. ...more
Bukittinggi's Volcanology and Geological Hazard Mitigation Agency (PVMBG) officer Suparmo is quoted that "the activity on Sunday was Marapi's strongest in recent days, although he noted that the alert level has remained at level II as the volcano's activity is showing a downward trend". [less]
