Question

Which statement describes the location of an earthquake’s epicenter? It is located using a single set of data. It is determined by the depth of the focus. It is determined by the arrival time of surface waves. It is located at the point where circles intersect on a map.

Answer 1

Answer: D

Explanation:

Answer 2

Answer:

It is located at the point where circles intersect on a map.

Explanation:

The name 'EPICENTER' was formed by a seismologist from Ireland can Robert Mallet.

An epicenter of an earthquake can be defined as the exact point in the center where as earthquake originated from.

An epicenter of an earthquake can also be defined as the point that is located directly above the focal point of an earthquake.

In other to be able to accurately determine the exact place where an earthquake happens, seismologist try to find out the distance of the earthquake from at least three seismic recording stations. The distance of the earthquake is obtained from a an equipment used by seismologist called seismograph. After obtaining the values if this distance, circles with the right radius are then drawn around each station. The point where the three circles meet or intersect shows us the earthquake's epicenter.
