The 25 April Nepal earthquake has killed more than 7,000 people and destroyed hundreds of thousands of homes. The deadliest earthquake in Nepal since 1934, the tremor killed at least 19 climbers and crew on Mount Everest and reportedly produced casualties in the adjoining countries of Bangladesh, China, and India.

In response, scientists at The Ohio State University and the University of Minnesota are directing supercomputing resources to aid in the disaster relief.
