What is considered a deep earthquake?

Shallow earthquakes are between 0 and 70 km deep; intermediate earthquakes, 70 – 300 km deep; and deep earthquakes, 300 – 700 km deep. In general, the term “deep-focus earthquakes” is applied to earthquakes deeper than 70 km. Previously, all earthquakes were considered to have shallow focal depths.

Are shallow or deep earthquakes worse?

Quakes can strike near the surface or deep within the Earth. Most quakes occur at shallow depths, according to the U.S. Geological Survey. Shallow quakes generally tend to be more damaging than deeper quakes. Seismic waves from deep quakes have to travel farther to the surface, losing energy along the way.

Are deep earthquakes common?
