If there was a tsunami warning in your area, could you escape on foot? That's the question a new tool released by the USGS takes on. The Pedestrian Evacuation Analyst takes into account not just foot-speed but terrain, and also highlights the areas of high-ground that would likely be the safest points.
After major urban disasters, there are always stories about the stubborn people who refused to evacuate. They've survived incredible danger, or worse, they haven't survived at all. But this isn't because they're foolhardy. There are good reasons that people stay in their homes, to protect their property at all costs.
