MSK Seismic Intensity Scale - MSK Seismic Intensity Scale

Japanese: MSK 震度階 - えむえすけーしんどかい

...In Japan, the Japan Meteorological Agency seismic intensity scale, which has 10 levels as shown in table, table (continued), is used, but in other countries, it is common to use 12 levels from 1 to 12, the most representative of which is the Modified Mercalli Seismic Intensity Scale (MM Seismic Intensity Scale) (1931). The MSK seismic intensity scale (1963) was also created with the aim of international commonality, but it has not been widely adopted. The Japanese seismic intensity scale was first established in 1884 with four levels: slight, weak, strong, and violent. In 1998, weak earthquakes were divided into weak earthquakes (weak) and weak earthquakes, and strong earthquakes (weak) and strong earthquakes, making it six levels. ...

*Some of the terminology that refers to the "MSK seismic intensity scale" is listed below.

Japanese:

…日本では表，表(つづき)に示す10階級の〈気象庁震度階級〉が使われているが，外国では1から12までの12階級のものを用いることがふつうで，その代表的なものは〈改正メルカリ震度階(MM震度階)〉(1931)である。また国際的に共用することをめざして〈MSK震度階〉(1963)が作られたが，あまり普及していない。日本の震度階は1884年に微･弱･強･烈の4階級のものを制定したのが初めで，98年に弱震を弱震(弱キ方)と弱震に，強震を強震(弱キ方)と強震に分け6階級とした。…
