Why do most earthquakes take place in tectonic plate boundaries?

Most earthquakes occur at tectonic plate boundaries because these areas are where the Earth's tectonic plates interact with one another. The movement of these plates can cause stress to build up along faults, and when this stress is released, it results in an earthquake. There are three main types of plate boundaries—convergent, divergent, and transform—each associated with different earthquake mechanisms. This tectonic activity at boundaries is a primary driver of seismic events worldwide.
