Volcanoes

Icelandic authorities have advised residents and employees in Grindavík against staying in the town as the risk of a new eruption and of cracks opening up increases.

The Popocatépetl volcano, just outside Mexico City, has been spewing thick plumes of volcanic ash into the sky, causing flights to be grounded.

The Kikai-Akahoya eruption — the largest volcanic explosion in recorded history — ejected more than 80 cubic miles of volcanic rock and ash off the southwestern coast of Japan 7,300 years ago.

Magma accumulating beneath Svartsengi has reached levels recorded on the eve of previous volcanic eruptions and could burst out imminently, according to the Icelandic Met Office.

While tracking seismic activity on Denali, scientists stumbled upon an anomaly that could indicate the presence of magma.

A volcano on Iceland's Reykjanes Peninsula erupted for the third time in three months, sending lava 2.8 miles west from the huge fissure in Earth's surface.

Magma flowed into the dike beneath Grindavík at a rate almost 100 times higher than what was seen in the eruptions that took place between 2021 and 2023.

The underground volcano near Grindavík has begun its third major eruption in three months, opening up a 2-mile-long fissure that is pumping out large amounts of lava and ash.

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.
