Roundup of Global Volcanic Activity

Batu Tara (Sunda Islands, Indonesia): The activity at the volcano remains intense. We visited Batu Tara from 30 June – 4 July on our recent Volcano Special tour and observed strombolian eruptions of varying intensity at intervals ranging between 10 and 50 minutes. The strongest explosions caused loud cannon-shot like noises and produced abundant incandescent ejections that reached heights and distances of up to approx. 500 m from the crater. They were followed by glowing avalanches of blocks rolling down the sciara to the sea. On 3 occasions within 16 hours between the evening of 2 and morning of 3 July, unusually strong eruptions produced small pyroclastic flows triggered by collapsing material from the eruption and small parts of the crater rim. These flows traveled down the sciara and over the sea for up approx. 200 meters.
