The P-wave from an earthquake arrives at a seismic station at 10:20 am and the S-wave arrives at 10:25 am. Assuming the P-wave velocity is 5 km s−1, and that Poisson’s ratio is 0.25, compute the time at which the earthquake occurred and its epicentral distance (in degrees) from the seismic station.

There are two types of seismic waves associated with every earthquake, called P and S waves. They travel in every direction away from the source of an Earthquake called the epicenter. Because they each travel with different speeds, seismologists can determine the distance from a seismic station to an epicenter. An earthquake occurred in an area when a P wave travels at 5 km/s and the S wave travels at 3 km/s. A seismic station measures an SP lag time...

P and S waves from an earthquake travel at different speeds, and this difference helps in locating the earthquake “epicenter” (where the disturbance took place). (A) If an earthquake occurs and these two waves arrive at a particular seismic station with the P wave 2.0 min ahead of the S wave, then how far away was the earthquake? Assume typical speeds of 8.5 km/s and 5.5 km/s for P and S waves, respectively. For part A i found 1.9 x...

S and P waves from an earthquake travel at different speeds, and this difference helps in the determination of the earthquake "epicenter" (where the disturbance took place). (a) Assuming typical speeds of 8.0 km/s and 5.7 km/s for P and S waves, respectively, how far away did the earthquake occur if a particular seismic station detects the arrival of these two types of waves 5.0 min apart? 5947840 KM IS INCCORECT WHAT IS THE CORRECT ANSWER?   km (b) Is one...

During an earthquake, seismic energy is released and it can travel long distance from source (location of the earthquake) to a seismic station. Path taken by a wave is similar to a ray (line with an arrow) which travels through the earth and arrives at a station. In the last assignment, we look into a case where earthquake is right beneath the station. In this assignment, we are going to investigate a case in which the station is far away...
