PVMBG reported that during 14-22 January brownish gray plumes from Tengger Caldera’s Bromo cone rose as high as 1.8 km above the crater. Seismicity fluctuated; the number of explosion signals increased and some shallow and deep volcanic earthquakes were recorded. The Alert Level remained at 3 (on a scale of 1-4); residents and visitors were reminded not to approach the crater within a radius of 2.5 km.
Based on information from PVMBG and satellite images, the Darwin VAAC reported that during 23 and 25-26 January ash plumes rose to altitudes of 3.6-3.9 km (12,000-13,000 ft) a.s.l. and drifted ENE, E, and SE.
