Dataset of spatial and temporal distribution of global strong earthquakes (1989-2018)


This data set is used to analyze the global activity level of strong earthquakes (Mw 5) in the past 30 years, and to present it spatially. It can be used to obtain the distribution areas of strong earthquakes with high frequency and activity level in recent years. By comparing the distribution of strong earthquakes in 2018 with that in 1989-2018, the distribution characteristics of global strong earthquakes in 2018 are obtained. The original data of strong earthquakes are from USGS, and the local density is calculated as frequency information. The magnitudes of all earthquake cases are interpolated globally, and then the frequency and magnitude are multiplied as the activity level of strong earthquakes. The data set is in TIff format with a spatial resolution of about 80 km. The data set can provide a reference for the analysis of strong earthquake activity level on the global scale, and is helpful for the analysis of global earthquake risk and the construction of earthquake prevention and disaster reduction system.


Data file naming and use method

The data format of global strong earthquake activity from 1989 to 2018 is Tiff format, and the name of the file is named by time period, 19892018. tiff.
The global strong earthquake event data of 2018 is SHP format, which can be opened by Arcgis. The file name is named by time period, 2018. shp.
