The magnitude M of an earthquake is related to the energy
If one earthquake has a magnitude of 5 on the Richter scale and a second earthquake has a magnitude of 6,
what is the relationship between the intensities of the two earthquakes?
The intensity of the earthquake and the reference intensity are related by the formula: R = log (I/Io). An earthquake in San Francisco in 1989 was reported to have a Richter number of 6.90. Compare the intensity of this earthquake to the reference intensity: San Francisco is ________ times more intense than the reference intensity.

- 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?arrow_forwardAn 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)?
