The level of volcanic activity decreased overnight, with a departure from the pattern that has existed for the last week. There was a volcano-tectonic earthquake swarm between 10:20 pm and 4:00 am. Unlike previous swarms, this one was not followed by a period of volcanic tremor. Since the end of the swarm, there has been an increase in rockfall activity, but the volcano is generally quiet this morning.
The crater area is obscured by cloud, so no observations have been possible so far.
The eastern side of dome is unstable, and further pyroclastic flows are expected in the next few days. 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.
