Map of the Weihe–Shanxi Rift System along the southern and eastern margin of the Ordos Block The 1556 Shaanxi earthquake (Postal romanization: Shensi), known in Chinese colloquially by its regnal year as the Jiajing Great Earthquake " 嘉靖大地震" (Jiājìng Dàdìzhèn) or officially by its epicenter as the Hua County Earthquake " 华县地震" (Huàxiàn Dìzhèn), occurred in the ...
The China seismic intensity scale is a national standard of the People's Republic of China [1] used to measure seismic intensity.Similar to EMS-92 on which CSIS drew reference, seismic impacts are classified into 12 degrees of intensity, or liedu (Chinese: 烈度; pinyin: lièdù, literally "degrees of violence") in Roman numerals from I for insensible to XII for landscape reshaping.
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". [3]
An earthquake's seismic moment can be estimated in various ways, which are the bases of the M wb, M wr, M wc, M ww, M wp, M i, and M wpd scales, all subtypes of the generic M w scale. See Moment magnitude scale § Subtypes for details. Seismic moment is considered the most objective measure of an earthquake's "size" in regard of total energy. [50]
So a 5.0 earthquake is ten times stronger than a 4.0. The magnitude and effect of an earthquake, according to Michigan Technological University: Below 2.5: Generally not felt. 2.5 to 5.4: Minor or ...

This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with modifications from both Richter and Beno Gutenberg throughout the 1940s and 1950s. [ 1 ] [ 2 ] It is currently used in People's Republic of China as a national standard ( GB 17740-1999 ) for categorising earthquakes.
