A seismic recording station located 4000 kilometers from the epicenter of an earthquake received the first P-wave at 7:10:00 p.m
agasfer [191]

We have that the time the earthquake occurred is mathematically given as

The <u>earthquake </u>occurred at =7:03:00 pm

<h3>Co-ordinates</h3>

Question Parameters:

A seismic recording station located 4000 <em>kilometers </em>from the epicenter

an earthquake received the first P-wave at 7:10:00 p.m. (h:min:s).

Generally

From t-x diagram, the x axis marks the distance of the <em>station </em>from the epicenter.

Hence we have that the P wave took 7 min to reach the station.

Arrival time of P and S wave is

dt=5 min 40 sec.

Therefore

The <u>earthquake </u>occurred at =7:03:00 pm

The S wave arrived at = 07:15:40 pm.
