Volcanic avalanches may be more destructive than previously thought
Pressures within these pyroclastic flows may be as much as three times as high as observations had suggested.

The ‘Doomsday’ glacier may soon trigger a dramatic sea-level rise
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.

Scientists Say: Avalanche
The word avalanche usually refers to a huge snowslide down a mountain, but it can also be used to describe any large mass of material tumbling downhill.

What can ‘silent earthquakes’ teach us about the next Big One?
Earthquakes usually last seconds. But sometimes, they can last days, or even years. Here’s what scientists are learning about these “slow-slip events.”

Scientists Say: Magma and lava
The word magma refers to molten rock deep inside Earth. That rock is called lava when it reaches Earth’s surface.

Rock rising from below the Atlantic may drive continents apart
Molten rock rising from the deep mantle at the Mid-Atlantic Ridge may drive plate tectonics there more than had been expected.

Scientists Say: Earthquake
An earthquake is a sudden and sometimes violent shaking of the ground.

Explainer: Earth — layer by layer
Explore the sizzling heat, unimaginable pressures — and some surprise diamonds — that sit beneath our feet. This is the side of Earth that you can’t see.

Explainer: Understanding geologic time
Geologic time is unimaginably long. Geologists puzzle it out using a calendar called the Geologic Time Scale.

How long will Kilauea’s new eruption last?
A government volcano expert answers burning questions about the ongoing Kilauea eruption.

Explainer: What makes dirt different from soil
Although most people use the terms dirt and soil interchangeably, scientists argue that they shouldn’t. Soil has provenance — meaning history. Dirt doesn’t.

Ancient Arctic ‘gas’ melt triggered enormous seafloor explosions
Methane explosions 12,000 years ago left huge craters in bedrock on the Arctic seafloor. Scientists worry more could be on the way today as Earth’s ice sheets melt.
