Explore how North America is changing as its deep cratonic root thins and pieces are dripping into the Earth's mantle.

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep inside the Red Planet.

When the waves cross the boundary between two different layers ... It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and ...

Large quakes produce shaking at a variety of frequencies. Some waves can travel hundreds of miles, and are amplified by local geological conditions.

Most scales are based on the amplitude of seismic waves recorded on seismometers ... video uses the analogy of a lightbulb to explain the how an earthquake can have different intensities at different ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

For example, S-waves cannot travel through ... Experimentation revealed that the seismic velocities of the dry, wet, and frozen samples are significantly different, which supports the ...

It is unclear what these structures are. If they were anywhere else, they could be portions of tectonic plates that have sunk ...
