Most severely affected was Haiti, occupying the western third of the island. An exact death toll proved elusive in the ensuing chaos.Explain what is meant by elastic rebound. Rocks can deform when stressed as with build up to an earthquake; when rocks snap back to their original shape after slippage, this is termed elastic rebound. What is the approximate duration of an earthquake that occurs along a 300-kilometer-long fault? 1.5 minutes.Induced earthquakes are caused by human activity while naturalearthquakes are caused by geologic processes.

The Modified Mercalli Intensity (MMI) Scale is a qualitative ranking system that describes the severity of shaking in specific locations during an earthquake. The scale is composed of increasing levels of intensity that range from imperceptible shaking to catastrophic destruction. Each ranking is assigned a Roman numeral from 1 to 10 (I-X).

The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place.The moment magnitude scale (MMS; denoted explicitly with M w or Mw, and generally implied with use of a single M for magnitude) 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.Similar to the local magnitude/Richter scale (M L ) defined …Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales , which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.
