Most earthquakes occur
at the boundaries where the plates meet
. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults
Do all earthquakes occur at plate boundaries?
Earthquakes happen every day all over the world
, along both tectonic plate edges and interiors. Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move relative to one another.
Do most earthquakes occur near plate boundaries?
Over
90% of earthquakes
– including almost all of the largest and most destructive ones – happen at or near so-called plate boundaries, where the 15 or so major subdivisions (“plates”) of the Earth’s crust and uppermost mantle move towards, alongside, or away from each other.
