What is the point where movement occurred wich trigger the earthquake?

The point where movement occurs that triggers an earthquake is known as the focus or hypocenter, which is the specific location within the Earth where the seismic rupture begins. Directly above this point on the Earth's surface is the epicenter, which is often used to describe the location of the earthquake. The movement typically occurs along a fault line, where tectonic plates interact, either colliding, sliding past each other, or pulling apart. As stress builds up due to these interactions, it is eventually released as seismic energy, resulting in an earthquake.
