Could happen with little warning.
According to geophysics professor Páll Einarsson, Hekla volcano in South Iceland could erupt at any moment.
Magma has been accumulating in the volcano and pressure readings are now higher than before the last two previous eruptions, says Einarsson, from the University of Iceland. That pressure will need to be alleviated.
Hekla erupted regularly every ten years or so from 1970 to 2000 – but has now been silent for sixteen years, reports the Icelandic news website visir.is (link in Icelandic),
“Hekla is ready – at any moment,” warns Einarsson.
