This map shows the land surface resized by its population overlaid with data about earthquake intensity records from a global listing of over 5,700 earthquakes from 2150 BC to the present. Each transformed grid cell in the map is proportional to the total number of people living in that area.
This map uses population estimates for the year 2020 based on data from the Gridded Population of the World (GPW), v4 at 0.25 degree resolution, released by SEDAC (Socioeconomic Data and Applications Center). The map overlay is a kernel density estimate using data derived from the Global Significant Earthquake database created by NOAA’s National Geophysical Data Center (doi:10.7289/V5TD9V7K). The database “contains information on destructive earthquakes from 2150 B.C. to the present that meet at least one of the following criteria: Moderate damage (approximately $1 million or more), 10 or more deaths, Magnitude 7.5 or greater, Modified Mercalli Intensity X or greater, or the earthquake generated a tsunami“.
