("Size" is used in the sense of the quantity of energy ...The intensity of an earthquake is the strength of the shaking caused by the earthquake. Intensity is measured on the Modified Mercalli Scale. This is a scale that is based on effects observed from the earthquake and to what degree those effects are felt. It ranges on a scale from 1 to 12, one being the lowest effects and 12 being total loss.This is the fifth earthquake in the magnitude 7 range to occur near Martinique since 1727. 2006 – 5.8 felt throughout Trinidad with 3 reported injuries in Point Lisas. 1997 (April 22) – 6.1 US # 25 million in damages to Tobago, 2 were injured and 15 were left homeless. 1996 – 5.2 North of Trinidad occurred New Year’s Day.Earthquake Dimensions - Rupture Size and Offset. Another measure of earthquake size is the area of the fault that slipped during the earthquake. During large earthquakes the part of the fault that ruptures may be hundreds of kilometers long and 10s of kilometers deep. Smaller earthquake rupture smaller portions of the fault.
The Richter scale is a measure of earthquake magnitude. That is, the strength of an earthquake. The bigger the quake, the bigger its magnitude on the Richter scale. Seismologists Charles Richter and Beno Gutenberg came up with this scale in the 1930s. They rated earthquake magnitude based on the biggest ground vibration — or seismic wave ...
