US, September 17, 2014: The US Geological Survey scientists have launched a new app ‘Pedestrian Evacuation Analyst’ to estimate time taken to walk out of a tsunami-hazard zone.
The web-based program employs GPS mapping data to plot a pedestrian route out of the tsunami danger zone.
The program on the basis of changes in different types of terrain and elevation tells if the user has enough time to escape to safety.
In case a person doesn’t have enough time, the mapping tool shows options for a “vertical evacuation,” or getting up high enough in a condo or secured building.
The software allows the user to generate maps showing travel times out of hazard zones and to establish the number of people that may or may not have enough time to vacate danger zone.
Jeanne Jones, USGS geographer who led the development project said, The tool can be used to offer valuable decision support for tsunami evacuation planning and vertical evacuation siting, which is just in the beginning stages in the U.S. Pacific Northwest,” said Jeanne Jones, USGS geographer who led the development of the software tool.
