February 19, 2012 – Mount Kanaga Volcano Exhibiting Explosive Activity: A view looking west, at the 1,312 meter (4,304 feet) high Kanaga Volcano in eruption. Kanaga is located about 25 km (16 mi) west of the U.S. Navy installation and port on Adak Island in the Aleutian Islands. The volcano erupted intermittently through much of 1994, dusting the community of Adak at least once with fine ash.
The Alaska Volcano Observatory has raised the alert level for the Kanaga volcano, in the remote Aleutian Islands.

February 19, 2012 – Mount Gamalama Volcano Comes Back to Life in the South-West Pacific in Indonesia: A major eruption at Mount Gamalama in North Maluku on Sunday night spewed volcanic ash 2,000 meters (6,560 feet) into the air and forced the closure of the airport in Ternate, the provincial capital.

There are now two possible reasons why this is happening. This might be an increase in hydro-thermal activity in north part of Katla volcano. Second reason might be that this is magma moving around inside Katla volcano at depth, then out visible effects on the surface. That is earthquakes have not happened following this event to any extent. There have only been two registered earthquakes so far. There location is both poor and depth poorly located.

Continued harmonic tremor in Katla volcano which may well come to nothing but is worth keeping an eye on.

This may just be a hydro-thermal thing!
