If an area experiences earthquakes frequently it is almost certainly near?

an active tectonic plate boundary. Earthquakes occur when stress builds up along faults in the Earth's crust, which is more likely to happen in regions where tectonic plates collide, pull apart, or slide past each other. These boundaries can be classified as convergent, divergent, or transform, each associated with specific seismic activity. Therefore, frequent earthquakes are a clear indicator of tectonic activity in the vicinity.
