WebUse the graph of distance versus P-S time interval (on Table 1) to more precisely determine the location of the epicenter of the earthquake. To determine how far the earthquake was from each seismic station, use the P-S time interval for a seismic station and read off the corresponding distance from the P-S time-interval graph. WebProcedure for Finding Richter Magnitude. Determine the S-P interval and an amplitude from the seismogram for the earthquake. Locate this S-P interval time on the S-P graph and find the distance to the epicenter. On the Richter nomogram, locate the distance to the epicenter on the left-hand column and the amplitude on the right-hand column. glasgow city council building control portal
