When an earthquake happens, energy travels through Earth in the form of seismic waves. These waves move outward from the earthquake source and create the shaking people feel on the surface. Scientists study earthquake wave types to understand: how earthquakes spread...

Earthquakes do not happen randomly. Before the ground suddenly shakes, Earth’s crust often spends years — or even centuries — slowly building stress underground. This process begins because tectonic plates are constantly moving. As Earth’s crust shifts: rocks bend...

Not all earthquakes happen because tectonic plates collide. Some earthquakes occur because tectonic plates move away from each other. These regions are called divergent boundaries At divergent boundaries: Earth’s crust stretches cracks form underground magma rises...

Some earthquakes happen because tectonic plates move directly toward each other. Others happen because plates pull apart. But transform faults are different. At transform faults, tectonic plates slide sideways past one another. This horizontal movement creates:...

Some of the world’s most powerful earthquakes happen in places called subduction zones. These massive tectonic boundaries form where one tectonic plate sinks beneath another deep into Earth’s interior. Subduction zones are responsible for: giant megathrust earthquakes...
