Why do we sometimes have earthquakes away from plate boundaries

Mantle flow

Explanation:

The mantle is the solid bulk of Earth’s interior which lies between Earth’s dense super-heated core and its thin outer layer, the crust.

The molten magma that surrounds the core was the early mantle.

Water trapped inside minerals erupted with lava through a process called “outgassing.” As more water was outgassed, the mantle solidified.

The rocks that make up Earth’s mantle are mostly silicate. The other major type of rock found in the mantle is magnesium oxide.

The temperature of the mantle varies from 1000°C near the crust, to 3700°C near the core. The viscosity of the mantle also varies.

*** The transfer of heat and material in the mantle helps determine the landscape of Earth. Activities in the mantle drives plate tectonics, contributing to volcanoes, seafloor spreading, earthquakes, and orogeny (mountain-building).
