This process results in geohazards such as earthquakes and volcanoes. …. This zone ‘locks’ between earthquakes such that stress builds up. It is then released catastrophically in one or more earthquakes. WebA hotspot forms when a plume of magma rises from the mantle and melts through whatever crust is above it. This new magma tries to reach the curface and creates a volcano. But when the tectonic plate shifts, new crust is suddenly above the hotspot, and a new volcano forms.

In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them.
