2007 Earthquakes
Earthquakes in 2007 resulted in many fatalities. The 2007 Peru earthquake was the deadliest with 595 fatalities. The September 2007 Sumatra earthquake was the largest in 2007 with an 8.4 on the moment magnitude scale. The 2007 Solomon Islands earthquake caused a significant tsunami that killed 52 people. There were five 8.0+ earthquakes in 2007 which is the most ever recorded for a single year. Other significant earthquakes in 2007 struck Chile and Japan.

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with 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 scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
