Explosions at Two Indonesian Volcanoes Force Mass Evacuations

Posted by feww on June 7, 2015

UPDATED

Mt Sinabung and Mt Karangetang erupt, forcing thousands of evacuations

The volume of lava in Mt. Sinabung’s crater has increased to more than 3 million cubic meters and the volcano is in unstable condition, reported PVMBG.

Up to 3,000 residents living within a 7-km radius of Mt. Sinabung, to the south and southeast of the volcano, have been evacuated according to the Volcanology and Geological Disaster Mitigation Center (PVMBG).

Mt. Sinabung’s alert level was raised to the highest level “AWAS,” last week.

The volcano has been ejecting large plumes of volcanic matter since last week, and observers have reported pyroclastic flows cascading down the sides of the mountain.

The 2,460-m high volcano, created by the subduction of the Indo-Australian Plate under the Eurasian Plate, is located in the Karo plateau of Karo Regency, North Sumatra, about 40km from the Lake Toba supervolcano.

Sinabung has four volcanic craters, but only one of them is active currently.


Approximate location of Sinabung is marked  on the map by FEWW. Mount Sinabung is one of Indonesia’s 130  active volcanoes

Meantime, activity continues at Mt. Karangetang, which is located in the district of Sitaro, North Sulawesi, forcing the evacuation of 339 people (106 families).

The “twin-peaked” Mt Karangetang (“Api Siau”), also one of the most active volcanoes in Indonesia, is located on the north side of Siau Island [pop: 43,000] North Sulawesi, in the Celebes Sea.

About 200 million Indonesians, or more than thee-quarters of the population, live within 100-km radius of one or more volcanoes that have become restive at least once during the past 100 years, according to researchers.

Batur, Bali (Indonesia);  Galeras, Colombia; Karangetang [Api Siau], Siau I; Mayon, Luzon;  Nevado del Huila, Colombia;  Piton de la Fournaise, Reunion Island; Reventador, Ecuador;  San Vicente, El Salvador

GVP Volcano News:

OVPDLF reported that on 5 November a vent inside the S part of Piton de la Fournaise’s Dolomieu crater opened, following an intense seismic crisis. Within thirty minutes, a fissure on the upper SE flank propagated E and a second fissure opened on the E flank.

PHIVOLCS reported that on 11 November an explosion from Mayon’ssummit crater ejected incandescent rock fragments seen from nearby areas. Cloud cover prevented observations of an ash plume, however fieldinvestigations after the event revealed ashfall to the SW.—GVP

Ongoing Activity:

Chaitén, Southern Chile;  Dukono, Halmahera;  Karymsky, Eastern Kamchatka;  Kilauea, Hawaii;  Kliuchevskoi, Central Kamchatka (Russia); Koryaksky, Eastern Kamchatka;  Rabaul, New Britain;  Sakura-jima, Kyushu;  Santa María, Guatemala;  Shiveluch, Central Kamchatka (Russia); Soufrière Hills, Montserrat; Suwanose-jima, Ryukyu Islands (Japan)

[Top] Activity at the west Waikupanaha ocean entry, where lava reached the ocean this past weekend, continues. The entry spans about 200 yards, with many small lava streams entering the water. [Above] On the east margin of the entry, lobes were advancing over a small black sand beach.  USGS/ HVO [Dated 4 Nov 2009] Click image to enlarge.

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
Thursday, November 5, 2009 7:48 AM HST (Thursday, November 5, 2009 17:48 UTC)

KILAUEA VOLCANO (CAVW #1302-01-)
19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Aviation Color Code: ORANGE
Aviation Color Code: ORANGE

Activity Summary for past 24 hours:
Growth and partial collapses of the Halema`uma`u Overlook vent cavity floor continued periodically obscuring and revealing the circulating lava pond surface. Sulfur dioxide emission rates from the Halema`uma`u and east rift zone vents remain elevated. Lava flows are active on the coastal plain. Lava is also flowing through tubes to the coast and entering the ocean at two locations west of Kalapana.

Past 24 hours at Kilauea summit:
The Overlook vent webcam images again showed fluctuating glow and spattering from a single elongated hole deep within the Halema`uma`u vent cavity; the rim of this hole was built progressively inward by spatter making the hole smaller until two more partial collapses occurred early this morning again revealing the circulating and spattering lava pond below. Glow from the vent was visible from Jaggar Museum overnight. This morning, a near white plume is moving southwestward and low over the Ka`u Desert. The most recent sulfur dioxide emission rate measurement was 500 tonnes/day on November 3, which is elevated above the 2003-2007 average of 140 tonnes/day. Small amounts of ash-sized tephra continued to be dropped from the plume near the vent.

Past 24 hours at the middle east rift zone vents and flow field: Magma continued to degas through Pu`u `O`o crater before erupting from the TEB vent, located 2 km to the east. The most recent sulfur dioxide emission rate measurement was 1,400 tonnes/day on November 4, which is close to the 2003-2007 average of 1,700 tonnes/day More …

Kilauea Spews More Lava

kilauea_ali_2009306
The rift zone on the eastern slopes of Hawaii’s Kilauea Volcano has been erupting since January 1983, the longest eruption in recorded history. Pu‘u ‘O‘o and the Thanksgiving Eve Breakout vent—two centers of volcanic activity—emit steam and other gases in this natural-color satellite image. Lava currently reaches the surface at the Thanksgiving Eve Breakout vent and flows southeast (towards the lower right) through a lave tube to the ocean. Small plumes of gas reveal the path of the lava. In general, the youngest lava flows are black, and older, weathered, flows are gray or brown. Surviving vegetation is bright green.

INGEOMINAS reported that on 28 October a pulse of tremor from Nevado del Huila was followed by an ash plume that rose to an altitude of 8.3 km (27,200 ft) a.s.l. On 3 November, residents of Mosoco (20 km SSW) saw collapses from the W side of the dome generate small pyroclastic flows and incandescence at night.

MVO reported that during 23-30 October seismic activity from the Soufrière Hills lava dome was at a slightly lower level that the previous week. Numerous pyroclastic flows occurred in most of the major drainage valleys and rockfalls were concentrated in the S. On 29 October, a 40-m-high spine was seen protruding from the summit. —GVP

1 – 7 October 2008

New Activity/Unrest:

Karangetang [Api Siau] Photo


Karangetang (Api Siau) volcano lies at the northern end of the island of Siau, north of Sulawesi. The 1784-m-high stratovolcano contains five summit craters along a N-S line. Karangetang is one of Indonesia’s most active volcanoes, with more than 40 eruptions recorded since 1675 and many additional small eruptions that were not documented in the historical record (Catalog of Active Volcanoes of the World: Neumann van Padang, 1951). Twentieth-century eruptions have included frequent explosive activity sometimes accompanied by pyroclastic flows and lahars. Lava dome growth has occurred in the summit craters; collapse of lava flow fronts has also produced pyroclastic flows. Photo by Volcanological Survey of Indonesia. Caption and details: GVP.
