Downloaded from hlayiso.com Source Ze Source 2F Three craters erupt in Iceland Voicanic eruptions in southern Iceland spewed lava, black smoke and white steam into the air and partially melted a glacier. The plume of smoke rose from a crater buried beneath 200 metres of ice. Authorities ordered 700 people to evacuate their homes because the melting glacier was about to cause floods. The police declared a state of emergency. Three Red Cross care centres opened in nearby villages to assist evacuees. The only deaths reported were two tourists who died of exposure whilst trying to see the volcano. Iceland sits on a volcanic hot spot on the Mid- Atlantic Ridge. This particular volcano, Eyjatjallajékull, has erupted five times since Iceland was settled in the ninth ‘century. The worst eruption was in 1783, when the volcano ejected poisonous gases. This caused the deaths of 9 000 people in Iceland. Winds then carried the poisonous gases south, and more than 2 000 people were killed in England and 16 000 in France. Pz
