Earthquake swarm reported at another Alaskan volcano
August 17, 2013
ALASKA – Seismic unrest is being reported at another Alaskan volcano. Tanaga is a 5,924-foot (1,806 m) stratovolcano located in the remote Aleutian Range of the U.S. state of Alaska. There have been three known eruptions since 1763. The most recent was in 1914 and produced lava flows. According to the Earthquake Report, a swarm of seven earthquakes have struck near the volcano in the last 24 hours- the strongest of which was a 4.7 magnitude. This may suggest magma intrusion under the volcano.
Number 69: Iceland – A small phreatic eruption seems to have taken place yesterday at the ice-covered Kverkfjoell central volcano. The steam-driven (no fresh magma involved) explosion followed a small glacial flood on 15 August the Kverkjökull glacier released into the Volga river and was probably a result of the pressure release during the flood. –Volcano Discovery
