Sinabung Eruption Leaves 14 Dead, Thousands Evacuated

Posted by feww on February 1, 2014

Sumatra volcano in deadly eruption

Mt Sinabung Erupted three times on Saturday leaving at least 14 people dead, including a group of school children from Medan on a science trip, and three others critically injured. Authorities were again forced to evacuate tens of thousands of people from 16 villages from the 5km – 7km exclusion zone near the volcano.

“This is the first direct impact of the Mt. Sinabung eruptions. Before the Saturday incident, the ongoing eruptions have already claimed the lives of 31 evacuees, as a result of various illnesses such as breathing difficulties, depression, asthma and hypertension.” Jakarta Post reported.

Some 14,000 of more than 30,000 evacuees had just been allowed to return home on Friday, following earlier eruptions.

Mass Evacuations as Sinabung Erupts Again

Posted by feww on January 8, 2014

Mount Sinabung Continues to Eject Volcanic Materials into the Air

Some 22,000 people living near Sinabung volcano have been evacuated Since Monday after the volcano erupted in North Sumatra, Indonesia.

The volcano is spewing columns of ash and smoke up to 4.5km above the summit crater, authorities said.

“The National Disaster Mitigation Agency (BNPB) has instructed all relevant ministries, government institutions, local disaster mitigation agencies and the Karo regency administration in North Sumatra to prepare for a worst-case scenario following an increase in Mount Sinabung’s volcanic activity during the past week,” said a report.

The “worst-case scenario” comes into if the exclusion zone is extended from its latest 7km radius, southeast slope of the volcano, to between 7.5 and 10 km from the crater.

More than 60 pyroclastic flows extending up to 5 km from the crater have been recorded with the flow volume increasing every day, said The National Disaster Mitigation Agency (BNPB).

The volume of volcanic material ejected so far is about a quarter of the total 2,540,000 cubic meters formed in Mt. Sinabung’s crater. “This means that the pyroclastic potential stored in the volcano’s lava dome is still substantial; so if it should all come out, the threat would be devastating,” Jakarta post quoted an official as saying.

Mass Evacuation Ordered as Mt SINABUNG Put on Red Alert

Posted by feww on November 24, 2013

18,000 people evacuated as Sinabung activity intensifies

Mt Sinabung’s latest explosive eruption has prompted the authorities to raise the volcanic alert to the highest level, “siaga,” or “red alert,” according to Volcanology and Geological Disaster Mitigation Center.

The alert level was raised from “orange” or “level III ” to the highest level “red” or “level IV” by PVMBG on Sunday, as the authorities evacuated an additional  11,618 residents from 19 villages and expanded the evacuation zone to a 5-km exclusion  zone from 3 km previously.

“This is Sinabung’s highest level of activity. The intensity of the eruptions continues to increase,” said Hendrasto, head of PVMBG.

As of 2 p.m. local time on Sunday, Sinabung was continuing to eject an 8-km high column of smoke and ash into the air, he said.

Some 6,000 villagers had already been evacuated from the 3-km exclusion zone, about 90 km from Medan, capital of North Sumatra province.

The North Sumatra health has distributed 180,000 face masks, medicine and 4 tons of baby formula to relief posts in Karo regency, reported Jakarta Post.

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.

VoW: Vesuvius

Country: Italy
Region: Campania
Volcano Type: Somma volcano
Last Known Eruption: 1944
Summit Elevation: 1281 m (4,203 feet)
Latitude: 40.821°N 40°49’17″N
Longitude: 14.426°E 14°25’34″E



One of the world’s most noted volcanoes, Vesuvius (Vesuvio) forms a dramatic backdrop to the Bay of Naples. The historically active cone of Vesuvius was constructed within a large caldera of the ancestral Monte Somma volcano, thought to have formed incrementally beginning about 17,000 years ago. The Monte Somma caldera wall has channeled lava flows and pyroclastic flows primarily to the south and west. Eight major explosive eruptions have taken place in the last 17,000 years, often accompanied by large pyroclastic flows and surges, such as during the well-known 79 AD Pompeii eruption. Intermittent eruptions since 79 AD were followed by a period of frequent long-term explosive and effusive eruptions beginning in 1631 and lasting until 1944. The 1631 eruption was the largest since 79 AD and produced devastating pyroclastic flows that reached as far as the coast and caused great destruction. Many towns are located on the volcano’s flanks, and several million people live within areas potentially affected by eruptions of Vesuvius. Photo by Dan Dzurisin, 1983 (U.S. Geological Survey).

[Note: A somma volcano is a volcanic caldera in which a new cone  has grown. The name comes from Mount Somma, a stratovolcano that hosts the cone of Mount Vesuvius. Other examples of somma  include volcanoes on  Kamchatka Peninsula (Russia) and the Kuril Islands that extend from Kamchatka to the island of  Hokkaido, Japan.]

13 August-19 August 2008

New Activity/Unrest:

Piton de la Fournaise. The massive Piton de la Fournaise on the island of Réunion is one of the world’s most active volcanoes. It is seen here in 1977 with a fresh black lava flow descending the outer NE flank of the shield volcano to the sea. An unvegetated summit lava shield (upper left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping northern rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera. (Caption:Global Volcanism Program ).
