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 seismic station sufficient to determine the position of the epicenter?

Yes/No

Explain.

Expert Solution

a)

b) No, in order to locate the epicenter we have to use a minimum of three stations because when we draw a circle corresponding to the distance to the epicenter from each station, the intersecting point of 3 circles will be a single point and it is more accurate.

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...

An earthquake emits both S-waves and P-waves which travel at different speeds through the Earth. A P=wave travels at 9000 m/s and an S-wave travels at 5000 m/s. If the P-waves are received at a seismic station 1 minute before an S-wave arrives, how far away is the earthquake center?

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...

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.

Waves travel at different velocity in different medium. How does wave velocity effect wave frequency?

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...
