Series of tremors and quakes rock Iceland volcano Katla

Iceland’s huge volcano Katla is stirring into life after tell-tale signs of the potential for an eruption were monitored by observers.

A harmonic tremor has been recorded for two days and small earthquakes have been confirmed at the volcano by the Icelandic Met Office this morning.

It is highly unusual for an eruption in Iceland to occur in the middle of winter but the early indications show Katla is building up power.

Experts are unclear as to whether it is water or magma that is causing this week’s sudden increase in activity and the seismic recordings are currently lower than when the volcano first showed signs of a minor eruption last July.

In September, Katla again stirred into life with a harmonic tremor and earthquakes in the volcano’s caldera – its magma chamber.

Katla, which has not experienced a significant eruption for 93 years, is the second largest volcano on Iceland and the consequences of a major eruption will be felt across Europe.
