Can cause damage to poorly constructed buildings and other structures in areas up to about 100 kilometers across where people live. 7.0 - 7.9. "Major" earthquake. Can cause serious damage over larger areas. 8.0 - 8.9. "Great" earthquake. Can cause serious damage and loss of life in areas several hundred kilometers across. "Foreshock" and "aftershock" are relative terms. Foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs.

Moment magnitude scale. The moment magnitude scale ( MMS; denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake 's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.

The duration of an earthquake is related to its magnitude but not in a perfectly strict sense. There are two ways to think about the duration of an earthquake. The first is the length of time it takes for the fault to rupture and the second is the length of time shaking is felt at any given point (e.g. when someone says "I felt it shake for 10 seconds" they are making a …A small earthquake, however, provides an ideal opportunity to offer reminders about safety measures to take before, during and after an earthquake.

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.
