6.895°S, 108.408°E; summit elev. 3039 m
All times are local (unless otherwise noted)
Ongoing seismicity continued during 27 October-30 November 2003 (table 1). The number of A-type volcanic earthquakes peaked during 3-9 November (53 events). Hot spring temperature measurements were 47°C at Sangkan Hurip, 50°C at Cilengkrang, and 43°C at Ciniru. No significant visual activity was reported, and the hazard status remained at Alert Level 2 (on a scale of 1-4).

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.
