Most dramatically of all, a large series of eruptions could destabilise many more subglacial volcanoes. As volcanoes cool and crystallise, their magma chambers become pressurised and all that ...

But a subglacial volcano -- one that is locked ... a fine sheet of volcanic debris that was propelled into the air by an eruption and settled back down on the ice around the volcano.

REYKJAVIK, Iceland — Iceland raised its aviation alert to red Saturday as a subglacial eruption began at the restless Bardarbunga volcano, which has been rattled by thousands of earthquakes in ...

This pressure means that melting ice can expedite the onset of an eruption from a subglacial volcano. Eruptions of subglacial volcanoes may not be visible on the surface, but they can have ...

More than 130 earthquakes were registered Tuesday at Iceland's large Bardarbunga volcano, a possible precursor to an eruption among the several scenarios being considered, the Icelandic ...

REYKJAVIK, Iceland -- Iceland raised its aviation alert to red Saturday as a subglacial eruption began at the restless Bardarbunga volcano, which has been rattled by thousands of earthquakes in ...

The pits indicate either an eruption or geothermal heating that is melting ice deep below the glacier's surface, according to the Met Office. Scientists can only detect a subglacial eruption at ...

This pressure means that melting ice can expedite the onset of an eruption from a subglacial volcano. Eruptions of subglacial volcanoes may not be visible on the surface, but they can have ...

So little is known about the bottom of the West Antarctic Ice Sheet that models of ice motion over it are unable to reliably predict what to expect from a subglacial eruption, noted Slawek ...

The small eruption seems to have come from beneath the Dyngjujökull glacier, according to the statement. About 328 to 1,312 feet (100 to 400 meters) of ice cover the still subglacial eruption.

From the amount of debris, Corr and Vaughan estimate that the eruption would have been similar in size to the subglacial eruption at Grímsvötn in Iceland in 2004. That event produced a hole in ...
