Epicenter
the tectonic plates are shifting under the earths surface.
By slowing down the earths rotation but will not make effect to humans .
The focus is the point in the earths crust where the earthquake originates and the epicentre is the point in the earths surface directly above the focus.
A crack in the Earth's crust that can lead to an earthquake is called a fault.
Near plate boundaries.
it is called the interior
The point on the earth's surface closest to the origin of an earthquake is called the epicenter. This is where the seismic waves generated by the earthquake first reach the surface.
The point beneath the earth's surface where an earthquake originates is called the hypocenter.
The point on Earth's surface directly above an earthquake's focus is called the epicenter. It is where the seismic waves originating from the earthquake's focus first reach the surface.
an earthquake
An earthquake is started when two plates (which lie under the Earths surface) rub together this creates movement which then sometimes pulls/pushes at the earths surface and creates giant cracks in the earths surface... and that is how an earthquake is started.
Focus
This is known as the epicentre.
Collide
epicenter
the tectonic plates are shifting under the earths surface.
Within the Earth, the focal point of the energy released in an earthquake is called the hypocentre or focus. This is where an earthquake actually begins. The place on the Earth's surface directly above this point is known as the epicentre.
