Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Katla’s ice cap is melting

Posted by feww on July 9, 2011

Melting of Katla’s ice cap is causing flooding near the volcano: Iceland Civil Protection Agency

Flooding may have been caused either by a small eruption, or geothermal heat emitted from the volcano, the authorities said.

Katla is one of Iceland’s largest and most active volcanoes. Located east of the Eyjafjallajökull glacier, near the southern end of Iceland’s eastern volcanic zone, Katla is buried beneath the Myrdalsjökull icecap. Its peak reaches 1,512 meters.

Katla’s last significant eruption occurred in 1928. The volcano is credited with sixteen major eruptions between 930 and 1918 occurring at intervals of 40–80 years.

Valley glaciers descend from the summit icecap toward the coastal plain in this aerial view from the SSW. Explosive eruptions from Katla, among the largest tephra-producers in Iceland during historical time, have frequently been accompanied by damaging jökulhlaups, or glacier-outburst floods.

    “The eruption of a lava dome in the summit crater of Cleveland Volcano continues. Satellite observations over the past week show that the edge of the dome is now at the level of the crater rim on the southwest and east-northeast sides, and may soon overflow the crater rim on these flanks.”
