Medium-term earthquake prediction



There is a worldwide effort to study and identify spatial and temporal variation of seismicity and recognize patterns that precede earthquakes “Mogi, 1969, 1984; Ohtake et al, 1977a, b; Habermann, 1981; Wyss et al, 1983; Liu Puxiong et al, 1984; Ohnaka, 1984–1985; and many others”.

Gupta and Singh “1986” carried out a detailed study of earthquake swarms and quiescence which precede major earthquakes in the northeast India region and concluded: 1. Moderate magnitude to great earthquakes in the northeast India region are found to be preceded, generally, by well-defined earthquake swarms and quiescence periods.
