Volcanic activity has been at a low level since the last episode of high amplitude volcanic tremor ended at about 4:30 pm yesterday. A few small rockfalls occurred at random throughout the night and a swarm of volcano-tectonic earthquakes which commenced at about 4:00 am this morning is still underway. This swarm is most likely to be a prelude to another episode of high amplitude tremor. If recent trends are followed this could occur sometime between 12:00 noon to 3:00 pm this afternoon.
The current pattern of activity is likely to continue, with regular swarms and tremor episodes, and some pyroclastic flows. The dome is growing as fast as it collapses, and so a repeat of yesterday's pyroclastic flow activity is possible. Residents are reminded to wear ash masks if there is ash in the air. The Tar River and upper Galway's areas are extremely dangerous, and should not be entered under any circumstances. Zone E, which includes Corkhill and the airport, remains safe at this time.
