HazPop Mobile App Now Available for Both iOS and Android Platforms

The Hazards and Population Mapper (HazPop) mobile app, a tool designed to put hazard-related data and information at your fingertips, is now available on both smartphones and tablets running iOS and Android. HazPop simplifies access to a range of distributed data services providing near-real-time data, including active fires and air pollution data (Aerosol Optical Depth) from NASA, earthquake alerts from the U.S. Geological Survey (USGS), and volcanic activity from the Smithsonian Institution's Global Volcanism Program. These data may be viewed in combination with data on population distribution and infrastructure, such as major dams and reservoirs and nuclear power plants, provided by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

Users interested in knowing how many people might be affected by a current or potential hazard may draw a circle around their own location or any other point of interest to obtain population estimates during the period 2000–2020.

HazPop is meant for those who need a quick assessment of the population potentially at risk from a major hazard event or developing emergency, such as disaster risk managers, humanitarian response organizations, public health professionals, and journalists. It is not intended to support in-depth risk assessment or estimation of actual disaster losses.

The app may be downloaded for free from the Apple App Store or from Google Play. It is compatible with iPhone, iPad, and iPod touch running iOS 9.0 or later, and with smartphones and tablets with Android 5.0 or later.
