All times are local (unless otherwise noted)


During January-May 2002, seismic activity at Kerinci was dominated by small explosion earthquakes. Plumes reached up to 600 m above the summit (table 2). An explosion during 0950-1030 on 4 May produced ash that rose 400 m above the summit. The Alert Level remained at 2 throughout the report period.

Geologic Background. Gunung Kerinci in central Sumatra forms Indonesia's highest volcano and is one of the most active in Sumatra. It is capped by an unvegetated young summit cone that was constructed NE of an older crater remnant. There is a deep 600-m-wide summit crater often partially filled by a small crater lake that lies on the NE crater floor, opposite the SW-rim summit. The massive 13 x 25 km wide volcano towers 2400-3300 m above surrounding plains and is elongated in a N-S direction. Frequently active, Kerinci has been the source of numerous moderate explosive eruptions since its first recorded eruption in 1838.
