![]() Geologists have little historical data from the area to use in predictions about such a quake, but they expect it could be huge when it happens: a magnitude 8.2 or bigger. Scientists say at least 140 million people in Bangladesh could be affected in the event of a big earthquake. ![]() The study suggested that the region could be on top of an active megathrust fault like the one that caused the 9.0 magnitude earthquake in Japan in 2011. When those expenses are normalized on a per-meter-squared basis (accounting for differences in construction costs across countries ), the following 15 countries rack up nearly all the damage: more than 75%.ĭhaka is the most crowded city in the world. They calculated that quakes cost us about $40 billion globally every year. "This allows one to get much more detailed information about the types of buildings, the population density, the potential for fatalities, the potential for damage, and economic loss essentially anywhere in the world," Schneider said.Īfter working on the maps for 10 years, the scientists realized that 15 countries account for most of the death and destruction wrought by earthquakes. The effort included hundreds of collaborators from public, private, and academic institutions around the world who worked together on what's now an open-source collection of maps. ![]() They took into account how fragile people's homes, schools and workplaces are how densely populated earthquake-prone regions are and, to some extent, what previous fatality numbers have been. They factored in the latest earthquake science, like ground-shake potential, as well as the human element: how exposed and vulnerable people are to earthquakes in different areas of the world. GEM scientists pinpointed which parts of the world are most at risk of earthquakes and where people can expect these disasters to do the most damage. ![]() "No one's ever created a global earthquake risk map at this level of detail before, and certainly not for the public," GEM Secretary General John Schneider told Business Insider.
