Pedestrian evacuation time maps for Puerto Rico tsunami-hazard zones

The communities of Puerto Rico are threatened by tsunamis from many earthquake sources (scenarios). Earthquake and tsunami modeling was conducted by experts to recognize as many earthquake sources as possible. Of the 34 tsunami scenarios developed, experts found that 16 could inundate some areas of Puerto Rico where people live and work with significant distance to safety. Pedestrian Evacuation Analyst Tool (PEAT) was run on to create 16 shapefiles of pedestrian evacuation travel time maps for 16 tsunami scenarios, modelled for slow walk (1.20 meters per second) evacuation travel speed. Thirteen shapefiles cover areas in the north shore and 3 cover the south shore and Punta Santiago.
