Students have asked these similar questions

An earthquake occurs 6,875 km from a seismograph. The P-waves arrive 11.6 minutes later. How fast is the P-wave traveling (in km/s)? If the lag time between P- and S-waves is 10.8 minutes, how fast are the S-waves traveling (in km/s)? Using the shadow of S-waves you determine that the radius of the core is 55% of the Earth's 6,378-km radius. How many kilometers from the surface is this (in km)? To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time. vP = d s vP = km/s

Calculate the surface wave magnitude MS for an earthquake with IMM of VII, in an area that can be approximated by a circle with radius 20 km for a site at the borders of the given isoseismal. This site is located in the western United States. Compare the ensuing value with the estimations from relationships with other magnitude scales. Calculate the fault surface displacements. Assume that the earthquake mechanism is normal faulting.

A seismic station located 60 km from the epicenter of an earthquake, recorded the maximum height of the S-waves to be 50 mm. What was the Richter magnitude of this earthquake?
