Increased volcanic activity is reported around the world.
Bogoslof is back to red alert, eruptions and increased activity are reported at Reventador (Ecuador), Erta Ale volcano (Ethiopia) and a quake swarm is currently rattling Katla (Iceland).
Supervolcanoes may erupt once, creating devastating conditions on Earth. Meanwhile smaller volcanoes are continuously active on Earth. Here a report:
After the eruption of Bogoslof volcano (Alaska) on January 22, 2017 (14:09 AKST / 23:09 UTC), the aviation code has been revised to red and the level of volcanic alert to Warning.
The strong explosion was detected by the lightning detection network in the absence of interpretable seismic data due to stormy winds. A plume of ash and gas was located by satellite reaching more than 9,000 meters and moving northward.
In Ecuador, the Reventador maintains high level of activity. IGEPN reported 3 episodes of emission tremor, 4 harmonic tremors, 25 LP earthquakes and 32 explosions.
A gas plume containing little ash was detected moving towards the north.
The thermal anomaly discovered by Mirova at Erta Ale volcano is currently very strong with energy peaks between 5,882 MW and 7,368 MW on January 22, 2017, after a maximum of 13,434 MW on January 21.
This image captured on January 19 by Sentinel satellite shows the overflow of the lava following the edge of the caldera.
Meanwhile, Katla wass experiencing a nice little swarm this morning!
