There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between ...

To understand how chaotic the early solar system was, we need only gaze at the moon. Its cratered surface bears the scars of ...

The Atlantic Ocean may have formed millions of years earlier than previously thought, igniting a period of climate change, scientists found.

Geoscientists have discovered a magma cap at Yellowstone National Park that is likely playing a critical role in preventing a ...

Ground sensors like those used on the moon and Mars can measure seismic waves. Balloon-based pressure sensors can measure infrasound waves, a form of low-frequency waves in the atmosphere created ...

The following is taken from Yellowstone Caldera Chronicles, a weekly column written by scientists and collaborators of the ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed they had a firm grasp on how these waves revealed the rocky mantle’s secrets ...

Ohio's recent earthquakes were minor — they were felt but did not cause major damage. For instance, the Noble County tremor ...

The answer is important to fundamental science questions about magma reservoirs as well as for understanding the potential ...
