How Does the Mercalli Scale Rate Earthquakes? - Civiljungle
WebFor earthquakes measured at distances greater than 600 km, magnitude can be estimated from the formula: Mb = log(A/T) + σ(D,h) Where A is the maximum amplitude (in micrometres) of the P-waves measured at period T (generally about one second) and σ is a calibration term (in the range 6–8) that depends on distance from the event D and depth … WebMost Americans are familiar with the Richter scale, which was developed by seismologist Charles Richter in 1935 at the California Institute of Technology. This scale is based on the largest shock wave recorded by a seismograph 100 km from the earthquake epicenter (the point on Earth’s surface directly above the rupture). plymouth state men hockey
