Alaska has the most volcanoes out of all the US states, but researchers think they don't have enough. Here's the weird science behind looking for Alaska's volcanoes, and what we've learned about volcanism along the way.

From an Australian fire that's been continually burning for millennia, to earthquakes that shake the ground for centuries, here are four natural disasters that lasted way longer than you might have expected.

For years, geologists have been searching for an explanation for two strange blobs of Earth's mantle that are denser than the rest. It turns out, they may not be original parts of Earth at all.

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

We all know ducks quack, dogs bark, and birds chirp, but that barely scratches the surface of all the amazing ways animals have devised to talk to each other!

The insides of the our gas giant friend, Saturn, might be less of a mystery now that we’ve figured out how to use its rings to indicate its internal makeup. And the light emitted from some very old, very hungry black holes could be...

You may have read that 2018 is looking to be a bad year for earthquakes, but Hank is here to offer you some assurances.

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

Devastating earthquakes happen every year, and it's difficult to predict when they will happen. But they do follow one mathematical pattern known as the Devil's staircase.

We’ve done a surprising amount of exploration on Mars, from its atmosphere, to its surface, and miles deep into its canyons. But mapping its insides has been a quandary that we hadn’t been able to solve until last week!

We use seismographs to record the time, location and magnitude of earthquakes as they happen. But in the last three decades, a new field of study has emerged that is learning to track these details about earthquakes of old using the...

On Tuesday the 22nd of February 2011 disaster struck the city of Christchurch. Why did it cause so much destruction? Earth ScienceGeology - Learning Points. New Zealand sits on a tectonic plate boundary between the Pacific plate and the...

Dr. Forrester demystifies earthquakes. She explains how they are created.

In this video, we learn about the reemergence of an island off the coast of Sicily due to seismic activity. The island, formed by a submerged volcano, has resurfaced multiple times in history, causing territorial disputes among nations....

The pool of boiling mud has already damaged local railroads and may damage pipelines, fiber-optic communication cables and highways in its path.

NASA’s InSight lander touched down in the Elysium Planitia region of Mars in November of 2018. During its time on the Red Planet, InSight has achieved all its primary science goals and continues to hunt for quakes on Mars....

This video is a lecture about seismic waves, specifically those produced by earthquakes. The video covers the basics of earthquakes, including where they originate and the different layers of the Earth. It also discusses the two main...

Many scientists believe that the Moon formed when a Mars-sized planet, called Theia, struck Earth around 4.5 billion years ago.

Hundreds were killed and more injured when earthquakes hit Japan on Thursday and Saturday morning and Ecuador on Saturday night. Despite occurring only 32 hours apart, experts believe the two are not related. The only commonality is that...

NASA’s InSight mission marks the first time humans have managed to directly map the internal layering of a planet other than Earth.

Experiments designed to mimic lunar or Martian surfaces

A volcano near Reykjavik, the capital of Iceland, erupted on Monday after a bout of seismic activity. The Reykjanes Peninsula is known for its frequency of volcanic and seismic events.

A 7.6 magnitude earthquake shook Mexico on Monday, causing people to gather in the streets for safety as seismic alarms blared.
