Volcanoes

Magma continues to accumulate in a chamber beneath Svartsengi and has now reached levels thought to have triggered the volcanic eruption that sent lava flowing into Grindavík on Jan. 14.

The Icelandic Met Office has warned magma beneath Reykjanes Peninsula is quickly reaching levels seen before the Jan. 14 eruption, and a fissure could open with just one hour of warning.

"This was a blast 150 times bigger still than Tambora's, disgorging enough pyroclastic rock to cover the whole of the United States to the depth of a one-storey home."

The ground below the Icelandic fishing town of Grindavík is so fissured and unstable following the volcanic eruption earlier this month that it could collapse, officials have warned.

A 500-foot-thick layer of pumice rock on the Mediterranean seabed indicates Santorini volcano ejected 15 times more material than Hunga-Tonga during a previously unknown eruption.

Satellite images reveal the heat still radiating from the reawakened volcano in Iceland.

Dams built to protect the Icelandic town of Grindavík from rushing lava may not be enough, a volcanologist cautions.

Iceland volcano appears to be gearing up for another eruption as more magma accumulates beneath the surface and the land around Svartsengi continues to rise.

Two fissures spewing lava opened up near Grindavík, destroying three houses in the town — and experts have warned new eruptions could take place any time.

A volcano on Iceland's Reykjanes Peninsula erupted on Sunday, cracking open fissures that are extending toward Grindavík and threatening to drown the town in lava flows.
