Sensors picked up a 3.8 magnitude earthquake earlier today.
And we wonder what is heating the oceans?
Created by hydrothermal activity beneath the ice?
Emissions of sulfur dioxide from the volcanic eruption at Bárðarbunga amounted to nearly 12 million tons.
The largest quake to have hit the famous volcano since it stopped erupting in February last year.
Over the past few months, seismic activity at Bárðarbunga Volcano (in Central Iceland) has been increasing, mainly under the volcano’s large, ice-covered caldera.
Fresh earthquake swarms over last the three days, along with fresh hydrothermal activity.
“We were lucky with the Holuhraun eruption as regards both timing and location,” says Sigurður Reynir Gíslason of the University of Iceland.
“Geologists are currently investigating signs that magma is building up again under Bárðarbunga,” says Iceland website.
The six-month event released 11 million tons of sulphur dioxide that spread over the country and the Atlantic Ocean towards Europe,
