Question

Why is it important of determining the epicenter of an earthquake?

Answer 1

The main importance in determining the epicentre is so that the fault that ruptured causing the earthquake can be identified. ... If the fault is previously unknown (such as the 2010 Canterbury earthquake), then it is important because it means that the hazard models for the area need improvement.

Answer 2

The major reason for establishing the epicenter is to identify the fault that caused the earthquake.

Important of determining the epicenter of an earthquake :

• The major reason for establishing the epicenter is to identify the fault that caused the earthquake.

• If the fault was previously unknown (like in the case of the 2010 Canterbury earthquake), it is significant because it indicates that the area's hazard models need to be updated.

• The focal point is the location within the ground where seismic waves originate, and it is located on the fault's most active section.

• The epicenter lies precisely above the focus on the earth's surface.
