Earlier today, a basketball-sized chunk of molten rock slammed into a tour boat off the coast of Hawaii, injuring 23 people and sending at least four to the hospital. The incident happened near the Kilauea volcano, which has been erupting since early May.

It’s been over six weeks since lava fissures began erupting on Hawaii’s Big Island, and there’s still no end in sight. New videos taken by the US Geological Survey reveal the dramatic extent to which the encroaching lava has reshaped the surrounding landscape, turning once gorgeous beaches into a smoldering pile of…

Molten lava from Hawaii’s Kilauea volcano has entered the grounds of Puna Geothermal Venture, a geothermal power plant that provides about 25 percent of the Big Island’s power.

As if the residents of Hawaii’s Big Island don’t have enough to worry about already, the US Geological Survey is now warning residents of yet another threat: large rocks shooting from Kilauea’s crater. Several rocks, including one measuring two feet wide, have already fallen— but the situation could get even worse.

The eruption at Kilauea volcano on Hawaii’s Big Island has technically been going on for over 30 years, but became a problem in recent weeks when a collapse on its eastern flank started draining its lava lake into surrounding parts of the island. It’s continued to get worse since then, and as of Sunday, CBS reported a…

The eruption of the Mount Kilauea volcano on Hawaii’s Big Island has continued to progress, with massive lava flows pouring out of what is now believed to be at least 10 fissures in the nearby residential neighborhood of Leilani Estates, the Washington Post reported.

Around 74,000 years ago, a massive caldera erupted on the Indonesian island of Sumatra, triggering a prolonged and devastating volcanic winter. Scientists have speculated that the Toba eruption pruned back human populations to a considerable degree, but new research published today suggests at least one group of…

The photos and video emerging from the Indonesian island of Sumatra right now are absolutely terrifying. Thankfully, no one has been hurt, but the smoke and ash bubbling from Mount Sinabung after an eruption earlier today is like watching some kind of mythical monster slowing taking over the sky.

Scientists knew something strange happened when they heard reports of a raft of floating rock near New Zealand back in 2012. That raft eventually grew to around 150 square miles—remains of the largest underwater volcanic eruption in the 20th or 21st century to date, bigger even than Mount St. Helens.

The big advantage to compact action cams like the GoPro is that they’re tiny enough to capture shots in places where regular cameras can’t fit. And as Hawaii volcano guide Erik Storm discovered, they’re also remarkably resilient, even to the point of surviving an 1,100+ degrees Fahrenheit lava flow.

Scientists have identified nearly 100 previously unknown volcanoes in West Antarctica, which, in addition to the 47 already known to exist in the region, makes it one of the largest concentration of volcanoes in the world.

There are certain mysterious phenomena in the world of Game of Thrones— like the reappearance of dragons, White Walkers, and the Children of the Forest—that the people of Westeros can neither quite explain nor agree upon if they’re real. Others, though, like the Doom of Valyria, are widely accepted as historical fact.

A vintage camera from the early 20th century containing a roll of undeveloped film has yielded an extraordinary set of images showing the 1980 eruption of Mount St. Helens, considered among the most disastrous volcanic eruptions in US history.

It’s not just the intense heat that makes it hard for researchers to closely study an active volcano, there’s also a potpourri of noxious gases that are less than ideal to inhale. But at the controls of a sensor-laden drone, scientists from the University of Cambridge have been able to capture amazing close-up footage…
