• EXPO-CAT

  Provides estimates of the number of people exposed to significant global earthquakes since 1973. Combines earthquakes in the Atlas of ShakeMaps with a gridded global population database (LandScan) to estimate present-day and historical population exposure at discrete levels of macroseismic intensity.

• Preliminary Determination of Epicenters (PDE)

  The NEIC global earthquake bulletin is called the Preliminary Determination of Epicenters or PDE. We use the word "Preliminary" for our final bulletin because the Bulletin of the International Seismological Centre is considered to be the final global archive of parametric earthquake data (phase pick times and amplitudes). The PDE bulletin goes through three stages of review. To get data for the entire PDE bulletin, files for all three review stages must be down loaded. There are no duplicate earthquake solutions in the files for the different stages of review. When an earthquake moves from one review state to the next the "old" solution is deleted.
