The earthquake's hypocenter, is where the crust's rupture begins.
*The epicenter of a quake is the point, on Earth's surface, associated with this hypocenter, which can be many kilometers inside the crust.
Epicenter
the point inside the earth where the first movement of an earthquake occurs and energy is released is called the epicenter.
The place on Earth's surface directly above the point where movement first occurs in an earthquake is called the epicenter. This is the point on the surface located vertically above the earthquake's focus (or hypocenter), where the seismic waves originate.
The point inside the Earth where the first movement of an earthquake occurs and energy is released is known as the focus or hypocenter. This is the location where the seismic waves originate and spread outwards, causing the shaking and vibrations associated with an earthquake.
epicentre
the epicenter
The point inside Earth where movement from inside an earthquake first occurs is called the focus or hypocenter. This is the location where the seismic energy is released, generating seismic waves that travel to the surface and cause shaking.
The point on the Earth's surface directly above the focus where an earthquake occurs is called the epicenter. It is the point where the seismic energy is first released and is typically where the strongest shaking is felt during an earthquake.
Focus
The name given to the point on a fault where the first movement or break occurs during an earthquake is called the hypocenter or focus. This is the point within the Earth's crust where the seismic waves originate and energy is released, causing an earthquake.
It is called an aftershock.
The earthquakes after a major earthquake in the same area are called aftershocks.
