New volcanic eruption

New Indonesian volcanic eruption halts victim search


A volcano in western Indonesia that killed 15 people in a weekend eruption shoots hot ash and rocks high into the air again, halting a search for any more victims

Volcanic unrest ripples across Indonesia: A lava dome emerged from the crater lake of Kelut following an eruption in 2007

February 3, 2014 – INDONESIA – The alert level of the volcano was raised today on Kelut or Kelud volcano from 1 (‘normal’) to 2 (“Waspada,” or ‘watch’) on a scale of 1-4. During the second half of 2014, a strong increase in seismic activity and a 5.5 deg temperature increase of the crater lake water had been detected. The number of shallow volcanic earthquakes rose from averages of 1-2 per day to approx 10 per day during 20-31 Jan and climbed to more than 100 events since the start of February alone. This might indicate a shallow intrusion is taking place and could lead to a new eruption. VSI had recommended a 2 km radius exclusion zone from the crater. The last eruption of Kelut was in Oct-Nov 2007, when a new lava dome grew within the crater lake. –Volcano Discovery


Kavachi undersea volcano (Solomon Islands) erupts


1 February, 2014


February 1, 2014 – SOLOMON ISLANDS – A submarine eruption is likely occurring at the submerged volcano. A NASA satellite image from 29 Jan shows a plume of discolored sea water swirling and drifting from the location of the volcano. The discoloration is likely from suspended volcanic sediments (the fragmented lava) and gasses. Kavachi is an undersea volcano on the southern edge of the Solomon Islands in the western Pacific Ocean. It erupted dozens of times in the 20th century, often breaking the water surface, only to be eroded back below the water line within a few months. Whether the new eruption will break the surface and create another new island remains to be seen. Directly above the undersea peak, a bright patch is visible that suggests vigorously churning water—but there is no sign that the eruption has broken the surface. (NASA) –Volcano Discovery
