What was the first instrument that actually recorded an earthquake? The earliest "seismoscope" was invented by the Chinese philosopher Chang Heng in A.D. 132. WebSinus Pressure. Magnitude calculations are based on a logarithmic scale, so a ten-fold drop in amplitude decreases the magnitude by 1.If an amplitude of 20 millimetres as measured on a seismic signal corresponds to a magnitude 2 earthquake, then:10 times less (2 millimetres) corresponds to a magnitude of 1;100 times less (0.2 millimetres) corresponds to magnitude 0;1000 times less (0.02 millimetres) corresponds An earthquake cannot physically occur at a depth of 0 km or -1km (above the surface of the earth). The user has almost instant knowledge of a seismic event when it occurs. When there is NO EARTHQUAKE reading, there is just a straight line except for small wiggles caused by local disturbance or "noise" and the time markers. 0000344634 00000 n
