Kelut Volcano, Island of Java

Location: 7.9S, 112.3E
Elevation: 1,731m
Last Updated: 2 February 2001

Kelut is an active stratovolcano on the east side of the island of Java. The Chinese recorded five eruptions of Kelut in the 14th century. Kelut has erupted 15 times in the last 200 years. The most recent eruption, in 1990, was explosive ( VEI=4) and produced a large cloud and heavy tephra fall. Tens of thousands of residents were evacuated before the eruption started. At least 32 people were killed, most by the collapse of their homes under the weight of tephra. More than 500 homes and 50 schools were destroyed. Pyroclastic flows reached 4-5 miles (7-8 km) away from the volcano. Fist-sized tephra fell 35 miles (55 km) southwest of the volcano. Dense tephra reached at least 7 miles (12 km) above the volcano. Subsequent lahars buried land used for agriculture. This photograph shows the crater lake of Kelut volcano. Photograph by John Dvorak, U.S. Geological Survey, March 11, 1982.

On 19 January, the Volcanological Survey of Indonesia raised Kelut's Alert Level from 1 to 2. The temperature of the crater lake increased and the volcano inflated 5.5-6 mm. On 21 January, a 5 cm increase in the water level occurred.

This information was summarized from Smithsonian Institution's Preliminary Notices of Volcanic Activity.
