The U.S. Geological Survey’s (USGS) Prompt Assessment of Global Earthquakes for Response (PAGER) system, operational since mid 2007, rapidly estimates the most affected locations and the population exposure at different levels of shaking intensities. The PAGER system has significantly improved the way aid agencies determine the scale response needed in the aftermath of an earthquake. Some engineering and seismological expertise is often required to digest PAGER’s exposure estimate and turn it into estimated fatalities and economic losses. This has been the focus of PAGER’s most recent developments. This book discusses the estimated economic consequences of large earthquakes along with an appendix of earthquake data.
