| Abstract: | For seismic disaster and risk assessment, scientist pay more attention to earthquake radiation energy ES and energy magnitude Me. Energy magnitude Me reflects the dynamic characteristics of the source, so it is more suitable to describe the potential destructiveness of earthquakes. In this paper, we given an introduction to the significance of seismic wave energy ES and seismic moment M0 as two physical quantities, and the definition and measurement method of energy magnitude Me. We mensurated the energy magnitude Me of the MS 7.0 earthquake in Jiuzhaigou, sichuan province on August 8, 2017, Me is 6.3. |
