Fears of explosive volcano eruption closes Kamchatka Airport

Predictions, that the Koryak Volcano located about 13nm north-north-east of Petropavlosvk-Kamchatsky Airport (Russia) on the Kamchatka peninsula might burst into an explosive eruption, have closed the Petropavlosvk-Kamchatsky Airport.
The Volcano has increased its eruptions in the recent days. Now collapses at the north-western slope of the 3456 meter high volcano at a height of about 3100 meters triggered fears, the volcano might burst into an explosive eruption. The volcano's last significant eruption was estimated about 3500 year ago, the last minor eruption was in 1957.

Just another at 3.2.
The average magnitude is markedly higher, across 16 quakes now in the last 29 hours. With an AVERAGE magnitude of over 3, something's not feeling right here. That's a bit high for a swarm AVERAGE, and in such a concentrated spot, and at such a similar depth. Hmm. Yup, I am finally gonna flag this thread.

The last eruption at Koryak was in 1956-57 that produced pyroclastic flows and lahars, a VEI of ~3 event. Beyond that, there isn’t too much known about the volcano’s past activity.
