Do you know the earthquake risk in your neighborhood? If not, that information is now available in the palm of your hand. Founded by two former U.S. Geological Survey (USGS) employees, Temblor is a free app that allows people to view interactive seismic hazard maps on their smartphones, tablets or computers. It also teaches U.S. homeowners to factor earthquake and landslide risk into their financial decisions, like where to live and what insurance to buy. The February issue of EARTH Magazine takes a closer a look at Temblor, highlighting the app's recent successes and goals for the future.
