Where does most seismic activity occur?

Most of seismic activity occur at the boundaries of tectonic plates.

Explanation:

Tectonic plates are in constant movement.

The movements of these plates result in the following types of limits:

Convergent: the plates approach each other. Divergent: the plates move away from each other. Transform: the plates move horizontally, past one another.

Small earthquakes are associated with convergent boundaries, and larger ones with divergent and transform.

The vast majority of the largest and most catastrophic earthquakes in history have occurred near the boundaries of tectonic plates.
