Hurricanes

Preventing flood hazards, such as hurricane-induced tidal surge, from becoming human disasters requires an understanding of the relative risks floods pose to specific communities and knowledge of the processes by which flood waters rise, converge, and abate. Historically, hurricane-induced tidal surge has been documented through measurement of high-water marks left on structures or vegetation...

Water-Use in Puerto Rico

The National Water-Use Information Program of the U.S. Geological Survey (USGS) is a cooperative program designed to compile, store, and disseminate water-use information locally and nationwide. Since 1950, the USGS has compiled data at 5-year intervals on amounts of water used in homes, businesses, and on farms in the United States, and has described how that use changed with time.

Where VS data are limited, available data are often used to develop and refine map‐based proxy models of VS30 for predicting ground‐motion intensities. In this paper,...
