2003 Altai Earthquake
The 2003 Altai earthquake, or 2003 Chuya earthquake, occurred on September 27 at with a moment magnitude of 7.3 and a maximum Mercalli intensity of X (''Extreme''). The epicenter of this oblique-slip shock was in Altai Republic, Russia near the borders of Mongolia, China, and Kazakhstan. Three deaths and five injuries were reported and the total damage was listed as $10.6–33 million. Earthquake This earthquake had components of right-lateral strike-slip and reverse movement in a segmented fault zone which had not been previously recognized. Damage Between 99 and 300 houses destroyed, along with 1,942 other buildings affected. It was the strongest earthquake in this region since an estimated magnitude 7.7 earthquake on December 20, 1761. Ground effects Landslides affected the Kosh-Agachsky and Ust’-Ulagan Districts.

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] |

Natural Disasters In Siberia
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
