Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. Intensity scales date from the late 19th and ...Quakes likely to cause the most destruction measure 7.0 and above. The 2004 earthquake which triggered the Asian tsunami was the third biggest quake since 1900. It measured 9.3.A better measure of the size of an earthquake is the amount of energy released by the earthquake, which is related to the Richter Scale by the following equation: Log E = 11.8 + 1.5 M (where Log refers to the logarithm to the base 10, E is the energy released in ergs and M the Richter magnitude).To enhance earthquake community resilience, it is important to address the gaps in community response to mitigation, preparation, and recovery of humanitarian disasters.

Earthquakes are measured by special machines called seismometers. Scientists use the numbers from 1 to 10 to say how strong an earthquake is. This number system is called a scale, or a magnitude scale. Magnitude means how big or strong something is. Higher numbers mean stronger earthquakes.epicenter: A point on the Earth's surface that is directly above the place where the underground forces of an earthquake originate. moment magnitude scale: Similar to the Richter scale, but replacing its use starting in the 1970s for more accuracy in measuring big earthquakes (magnitudes > 3.5) from greater distances.Earthquakes are measured using seismographs, which monitor the seismic waves that travel through the Earth after an earthquake strikes.
