According to the Darwin VAAC a pilot observed a small "smoke" plume rising from Cereme on 24 June; ash was not identified in satellite images.
Geological Summary. 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.
