Volcanos

Roundup of Global Volcanic Activity

Sakurajima (Kyushu, Japan): The volcano has been getting more active again during the past night: a series of small explosions and associated ash emissions occurred from the older summit crater, Minamidake. It will be interesting to see whether or not Sakurajima returns to its previously so typical style of intermittent, often quite powerful vulcanian-type explosions (at rates ranging from one every few days to several per day).

Popocatépetl volcano (Mexico): The volcano's activity has been essentially unchanged over the past week. On average, 2-4 explosions have been occurring daily - mostly small events with plumes less than 1 km tall - and about 50-100 pulses of steam emissions ("exhalations”). Glow at night visible from the crater indicates that magma continues to slowly rise and accumulate there. The official alert level remains at "Yellow Phase 2".
