China seismic intensity scale

The China seismic intensity scale is a national standard of the People's Republic of China 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.
