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 .

The unvegetated summit of 3800-m-high Gunung Kerinci in central Sumatra, Indonesia’s highest volcano, is seen from Pengamatan on its southern flank. 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.

Tropical Cyclone Bijli

Posted by feww on April 21, 2009

TC Bijli dumped as much as 50 mm of rain per hour in parts of Bangladesh, India and Myanmar

Tropical Cyclone Bijli came ashore over eastern Bangladesh on April 17, 2009. The storm caused little damage, according to news reports, but did dump as much as 50 millimeters of rain per hour in the regions where rainfall was heaviest, shown in red, on Bangladesh and neighboring Myanmar. This image, made with data captured by the Tropical Rainfall Measuring Mission (TRMM) satellite on April 17, shows the rainfall associated with the storm.
