All times are local (unless otherwise noted)


DVGHM raised the Alert Level at Cereme to 2 (on a scale of 1-4) on 13 October after increases in seismic and volcanic activity. During 13-19 October, the seismic network recorded 36 deep-volcanic earthquakes. Seismicity decreased during 20-26 October, with 7 deep-volcanic earthquakes recorded.

Geologic Background. The symmetrical stratovolcano Cereme is located closer to the northern coast than other central Java volcanoes. A large crater elongated in an E-W direction, formed by multiple vents, caps the summit of Gunung Cereme, which was constructed on the northern rim of the 4.5 x 5 km Geger Halang caldera. A large landslide deposit to the north may be associated with the origin of the caldera, although collapse may rather be due to a voluminous explosive eruption (Newhall and Dzurisin, 1988). Eruptions have included explosive activity and lahars, primarily from the summit crater.
