Alert level raised on Indonesia’s Kelut volcano in East Java, following seismic swarm

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
