Strong spattering and a lava flow from the new cone in the eastern vent of Bocca Nuova on the evening of 3 Aug 2012No major volcanic activity is happening at the moment. Here are some updates on current activity at some volcanoes, most of which are semi-permanently active:
Etna (Italy): An increase of activity started on the evening of 3 Aug. We observed increasing strombolian activity and near-continuous spattering in the Bocca Nuova, and strong SO2 emissions from the New SE crater.
Batu Tara (Sunda Islands, Indonesia) produced an ash cloud reaching 1.8 km altitude on 4 Aug.
Nevado del Ruiz (Colombia): Weak tremor and gas and ash emissions continue. The volcano remains at orange alert. The other volcano in Colombia of major concern, Galeras, is relatively calm these days.
Popocatépetl in Mexico: The activity at Popocatépetl remains at low to moderate levels compared to previous weeks. A medium to large explosion occurred at 18:04 local time on 3 Aug and produced an ash cloud rising 2.5 km and drifting west.
Sakurajima volcano: The rate and intensity of explosions have dropped over the past days. Only two small eruptions have occurred at 21:06 and 03:19 UTC on 3 Aug producing ash clouds rising to 1.5-1.8 km altitude.
Tongariro (New Zealand): Seismic unrest continues with tremor and earthquakes visible on the seismic recordings for the volcano. No new reports from GeoNet in New Zealand, but the alert level remains at 1.
