The tremor caused several buildings to collapse, burying people in the wreckage.

The bubbles are the result of magma being rapidly cooled by water as it shoots out of underwater vents.

Water has been steadily rising in the pool since it was discovered at the end of July.

USGS scientist addresses spike in internet searches for Yellowstone caldera after the quakes.

The U.S. Geological Survey recorded a strong aftershock less than 24 hours after a 6.4 magnitude earthquake that struck California.

Scientists estimate that the dead zone could grow to around 7,829 square miles—or about the same size as the state of Massachusetts.

Fortunately, the earthquakes were not powerful enough to cause any damage or injuries on the surface.

Hawaii Volcanoes National Park official said the man was taken to hospital for urgent care.

A new report from the U.S. Geological Survey assesses the risk of volcanic eruptions across the state.

Misinformation, one scientist said, "causes unnecessary and unfounded anxiety" about the iconic national park.

The eruption has created a 12,000 foot ash cloud.

Research geologist Laszlo Kestay said the USGS has been paying "close attention" to space resources for years.

The emissions from the volcano have lowered to pre-eruption levels.

Lava flow has almost stopped, but eruptions could still occur.

It's headed for the boat ramp in Isaac Hale Park.

One of the most recent island locations to be overrun with lava was Ahalanui Beach Park and the Kua O Ka La Public Charter School.

Coagulated volcanic spatter has created a 200 feet cone that should last for thousands of years.

The device was meant to measure crater collapse.

Plumes of acid rain, vog and lava continue to plague Hawaii's Big Island.

Kīlauea has been particularly active over the past few weeks.

The first report of an eruption-related injury from the active Kilauea volcano in Hawaii occurred Saturday after a homeowner's lower leg was "shattered" by a "lava bomb."

2,000 people have been told to evacuate and more could follow if authorities fear escape routes are under threat.

The eruption could also bring acid rain.

"There's currently no way to get a message quickly enough from our system to the public because none of our systems were built for speed."

Other vulnerable countries have had systems in place for years.

Scientists assess past eruptions to try to understand what will happen with the supervolcano.

Oklahoma is also at risk, and New York City is vulnerable.

The volcano has erupted dozens of times since January.

Earthquake swarm is currently active on the western edge of Yellowstone National Park.

The eruption risk at Yellowstone remains low, but one of the recent earthquakes was the biggest to have hit since 2014.
