Webmany important seismographic systems, the electrical current from the seismometer was used to drive galvanometers. These galvanometers consisted of a mirror suspended on a torsion wire. Deflection of the mirror was measured photographically as in other direct seismometers. The galvanometer was itself a linear SDOF whose forcing was the output Web27 feb. 2010 · ScaleFreq : 0.02 Hz = this is the frequency at which the scale is accurate. ScaleUnits : 1 unit = 1 M/S (meter/second) SampleRate: 20.0 samples/sec. So a “count” value of 3.27508e9 would indicate ground motion of 1 m/s — you can divide the count value by 3.27508e9 to convert into meters per second.

How are Earthquakes Measured? Magnitude

WebA scale for comparing the intensities of earthquakes was devised around 1940, by a man named Charles Richter. The intensity of an earthquake is measured by the amount of ground motion as measured on a seismometer.
