Question

The longer the time between the arrival of the P-wave and S-wave, the _______ is the epicenter.

Answer 1

The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter.

What is epicenter and the relation between P-wave and S-wave?

• The point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins is said to be epicenter.
• There are two types of waves during earthquakes, they are:

1. P - wave
2. S - wave

• Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive.
• From the graph, through the information, scientists can determine how fast the waves are traveling.
• The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter.

Hence, Option B is the correct answer.
