Question

Quizplus · Accepted Answer

Deep-hypocentre earthquakes occur only in association with subduction zones. These earthquakes result from the downward movement of a tectonic plate into the Earth's mantle, where it generates tension that is eventually released as an earthquake. This process occurs specifically at subduction zones, where one tectonic plate is forced beneath another.
