Overview of worldwide earthquake disasters in 2020

Abstract

Based on the earthquake disaster data collected worldwide，this paper sorts out the global seismic activity and disasters in 2020. Plotting the global earthquake disaster curves in recent 20 years and distribution map of hazard earthquakes in 2020，and summarizing the main characteristics of seismic disasters which contain earthquake disaster information and detailed analysis in 2020. Compared with the previous global earthquakes，it is found that the seismicity in 2020 is weak，and the frequency of strong earthquakes with magnitude 6 or above will decrease greatly. In 2020，the earthquake casualties are the lowest in this century，and characterized by low frequency，minor casualties and linear distribution of major disasters. According to the situation of low earthquake frequency and concentrated casualties，this paper puts forward corresponding measures and suggestions for earthquake disaster prevention，which emphasizes that the earthquake monitoring，prediction and prevention work are crucial to the future.
