  • The New Zealand quake is described as having a focal depth of about 23 kilometers (14.3 miles). What is focal depth? Is 23 kilometers a deep or shallow focal depth?
    • The focal depth of an earthquake is how far below the surface of an earthquake’s epicenter the actual rupture, slip, or dip took place.
    • Earthquakes can take place anywhere between one and 700 kilometers below Earth’s surface, so 23 kilometers is a pretty shallow depth.
