The eruption of Okmok Volcano continues. Seismicity increased overnight from around midnight to 03:00 AKDT (08:00 – 11:00 UTC), but has declined somewhat since then. Currently, seismicity consists of episodic pulses occasionally grading into continuous volcanic tremor.

Stronger explosive activity could resume at any time with little or no warning.
