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.
