The Alps’ Matterhorn shows how much even big mountains sway
Such mountain sway data can help planners map high-risk zones for peaks, bridges or any large structures.

Such mountain sway data can help planners map high-risk zones for peaks, bridges or any large structures.
Pressures within these pyroclastic flows may be as much as three times as high as observations had suggested.
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.
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
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.
Earthquakes usually last seconds. But sometimes, they can last days, or even years. Here’s what scientists are learning about these “slow-slip events.”
The word magma refers to molten rock deep inside Earth. That rock is called lava when it reaches Earth’s surface.
Humans are changing the world in profound ways. Some scientists think those changes have launched a new epoch in Earth’s history: the Anthropocene.
Data showing this association go back at least 360,000 years.
