Klyuchevskoy Volcano Erupts Explosively

Posted by feww on June 14, 2016

Klyuchevskoy ejects column of ash 6-8 kilometers a.s.l.

The latest eruption, detected Tuesday morning, saw the ash column rising 6-8 kilometers into the air. The plume stretched for 47 kilometers to the west of the volcano, Russia’s Institute of Volcanology and Seismology FEB RAS (KVERT) reported.

  • Aviation Color Code: ORANGE
  • Current State: Ash plume extended 47 km to the west from the volcano.
  • Danger Prognosis for Aviation: Explosive eruption of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.
  • Volcanic cloud height: 16400-19680 ft (5000-6000 m) AMSL Time and method of ash plume/cloud height determination: 20160613/2209Z – Video data
  • Other volcanic cloud information: Distance of ash plume/cloud of the volcano: 29 mi (47 km)
  • Direction of drift of ash plume/cloud of the volcano: W / azimuth 274 deg
  • Time and method of ash plume/cloud determination: 20160613/2129Z – NOAA 18 (4m5)

The 4,750m volcano in Russia’s Kamchatka peninsula has been continuously active for the past five decades, with the number of tremors and ash eruptions notably rising recently.

Mt Sinabung Eruption Turns Deadly

Posted by feww on May 22, 2016


Superheated pyroclastic flows roar down Sinabung flanks, killing or injuring villagers in Sumatra

At least a dozen people were killed or seriously injured after Sinabung erupted on Saturday, ejecting large clouds of smoke and ash about 3km into the air, as an avalanche of superheated pyroclastic flows descended down the mountain  inundating the village of Gamber.

The victims are thought to be local villagers farming within the 4-kilomere exclusion zone when they were consumed by pyroclastic clouds.

“People and visitors/tourists are not allowed to conduct any activity within a radius of three kilometers from the mountains top. People living in the south and southeast sector are also prohibited to get as near as seven kilometers from the mountains top while those in north and northeast sectors are prohibited to get as near as four kilometers from the mountains top,” said an official at the National Disaster Mitigation Agency (BNPB), Sutopo Purwo Nugroho.

About 60,000 people have been displaced since Sinabung volcano awoke in 2013 after a period of dormancy.

Indonesia has 129 active volcanoes, of which at least 79 have erupted since the 1600s. Some 66 volcanoes are continuously monitored from 76 observatories.

Turrialba Volcano Erupts Violently

Posted by feww on May 21, 2016


Hell Hath No Fury Like the Primed Costa Rica Volcano!

The powerful explosion, said to be the volcano’s most powerful eruption in 6 years, ejected a thick column of ass and smoke more than 3km into the air.

Hundreds of people have inundated the local hospitals, complaining of breathing difficulties and skin burns, as multiple layers of ash covered the buildings and roads, and a strong stench of sulfur filled the air.

The 3,343-meter Turrialba Volcano, located in central Costa Rica, about 45km east of the capital, San Jose, began activity on Wednesday with the first wave of eruptions occurring on Friday, officials said.

Turrialba Volcano Explodes Again

Posted by feww on May 13, 2016

Costa Rica’s Turrialba Volcano Erupts

Volcanologists at the University of Costa Rica have reported a large explosion at Turrialba Volcano, which occurred in the early hours of Thursday local time.

The powerful eruption ejected ash to a height of about 3 kilometers above the volcano’s summit, according to the Volcanological and Seismological Observatory of Costa Rica (OVSICORI).

“It was a single explosion but a really strong one. This means that there was high pressure inside the volcano,” said a volcanologist at OVSICORI.

The ashfall forced the closure of Tobías Bolaños Airport, in western San José, local media reported.

The 3,340-meter-high volcano is located about 65km northeast of the capital, San Jose.

In October 2014, authorities in Costa Rica evacuated nearby residents after Turrialba’s largest eruption in 148 years. Large areas of San Jose, La Union, Cartago, Santo Domingo and Heredia provinces, located as far as 50km from the crater, reported volcanic ash and strong sulfur odors.

Bristol Island Volcano Erupts after 60 Years

Posted by feww on May 5, 2016


Bristol Island Volcano Joins the Global Volcanic  Unrest

Bristol Island volcano, one of South Sandwich Islands group, formed near East Scotia Ridge in Antarctica, is erupting for the first time in 60 years.

Bristol Island is an 8 km long volcanic island in the South Sandwich Islands, located between Montagu Island and Thule Island.

The Island is composed of several active volcanoes with eruptions reported in 1823, 1935, 1936, 1938, 1941, 1950, 1956 and 2016.

A powerful earthquake measuring 7.3Mw occurred at a depth of 31km about 216 km SSE of Bristol Island on 15 Jul 2013, according to USGS/EHP.

A cluster of 15 earthquakes measuring ≥ 4.6Mw have struck the East Scotia Ridge since April 8, 2016, with largest event measuring 5.9Mw.

Sumatra’s Mt Kerinci Erupts

Posted by feww on April 21, 2009

Sumatra’s Mt Kerinci volcano erupts at least 3 times

Mount Kerinci, the highest mountain in Sumatra, is undergoing a period of unrest, punctuated by at least three explosive eruption, spewing smoke and ash into the air.

The local volcano observation monitor also reported  repeated tremors at the base of the volcano.

Two explosive eruptions were reported Sunday and Monday, spewing smoke and ash to a height of about 400m with ash covering the tea plantations on the mountain slope and posing a threat to the populated areas below.

Another, less powerful, explosion reportedly occurred earlier today.

The head of Mount Kerinci Observation Post was reported as saying that Kerinci volcano has been showing signs of unrest in the past week.

“We have warned local people to remain cautious. We told them it’s better to wear mask when going outdoor,” he said.

One of the most active volcanoes  in Indonesia, the 3,800-meter high Mt. Kerinci, a stratovolcano,  sits on the border of Jambi and West Sumatra .

Kerinci is one of the most active volcanoes in Sumatra and has been the source of numerous moderate explosive eruptions since its first recorded eruption in 1838. The massive 13 x 25 km wide volcano towers 2400-3300 m above surrounding plains and is elongated in a N-S direction.

FEWW Volcanic Forecast:

1. The Loyalty – New Hebrides  Arc Collision. Intense volcanic activity should be expected throughout 2009 and beyond along the New Hebrides arc, the Vanatu region (also to the north to include Solomon Island and Santa Cruz Island), possibly continued along the New Hebrides Trench (to include Matthew and Hunter Island). Volcanoes that are located in the above-described area include:

  • Savo (Solomon Island)
  • Tinakula (Santa Cruz Island – SW Pacific)
  • Suretamatai
  • Motlav
  • Gaua
  • Mere Lava
  • Aoba
  • Ambrym
  • Lopevi
  • Kuwae
  • North Vate
  • Traitor’s Head
  • Yasur
  • Eastern Gemini Seamount
  • Matthew Island
  • Hunter Island

2. Pacific Plate subduction beneath the Okhotsk Plate. Subduction of the Pacific Plate beneath the Okhotsk Plate continues to create Intense volcanism. Starting 2009, however, a much greaterthan the average number of volcanoes located on the Kuril Islands island arc, Kamchatka volcanic arc and Japan trench to the south may erupt with renewed intensity.
