Kelud volcano (also spelled Kelut) is one of East Java's most active volcanoes. The volcano has a spectacular large crater that contains a lake, which was a popular weekend destination but also the origin of devastating mud flows (lahars). In Oct-Nov 2007, a new lava dome grew within the lake to form an island, replacing most of the water.
Kelut is notorious among Indonesia's volcanoes for its violent, and often deadly explosive eruptions. One of the worst volcanic disasters occurred during the 1919 eruption, when the (then very large) crater lake drained and formed lahars that killed at least 5160 people. An eruption in 1586 is believed to have caused even more than 10,000 fatalities.

Kelut volcano (East Java, Indonesia): seismic swarm, alert level increased
Tuesday Feb 11, 2014 07:35 AM | BY: T
Seismic activity at Kelut volcano during the past weeks (VSI)  Hypocenters of recent earthquakes under Kelut volcano (VSI)
VSI raised the alert status to the second highest level 3 (out of 4), "Siaga" (meaning eruption warning). In its latest report, VSI informs that an ongoing slight deformation, suggesting magma intrusion, has been detected since September and that a strong increase in seismic activity started on 7 February. A seismic swarm occurred with hypocenters between 1.5-3.5 km depth beneath the summit area.
The increased seismic activity triggered the decision to raise the status once more, after the volcano had put on alert level 2 already on 2 Feb.

The alert level of the volcano was raised today from 1 ("normal") to 2 ("Waspada", "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. ...

CVGHM lowered the Alert Status of Kelut on 8 November from 4 to 3 (on a scale of 1-4), due to a decrease in seismicity and deformation. Temperatures of the crater lake were measured at 75 deg C on 6 Nov, and 150-210 deg C on the surface of the new lava dome. According to a local news article, a volcanologist reported that the lava dome was 250 m in diameter and 120 m above the crater lake surface. On 11 November, a plume rose to an altitude of 3.7 km (12,000 ft) a.s.l. and ashfall was reported in several areas.
CVGHM recommended that evacuees could return to their homes, but should stay clear of the mountain within a 3-km radius was restricted.

The Center of Volcanology and Geological Hazard Mitigation (CVGHM) raised the altert status of Kelut volcano on 16 October from 3 to 4 (on a scale of 1-4). During 15-28 September, gas discharge from the crater lake increased and spread in a radius of 5 m. Inflation around the summit occurred during 13-16 October. On 16 October, the temperature in the crater lake increased to 37.8 degrees C. ...
