In the days following the earthquake in Japan, members of the Business Civic Leadership Center pledged more than $240 million to aid response and recovery efforts. Their challenge was to figure out how to dispense that money to the projects and people who needed it most. To help them visualize the scope of the disaster and identify the areas that were most affected, we developed an interactive map of the aftershocks felt at more than magnitude 5.0 in the days after the initial 9.0 quake.
