Earthquakes in this area have continued to occur at a frequent pace, with 2 over M5 during the past hour. Given that those islands have many volcanoes, I looked at the AVO site, which didn't say that any were active. However, looking at the webicorders for several nearby volcanoes - they all show the earthquakes, but the one for PAVLOV shows a long harmonic tremor. This is often a sign of magma moving below the volcano. On the copy below - note the thick line between 18:00 and 22:00 ADT (time on left):
