High-powered computers let researchers create simulations that can reveal important clues as to what may happen next, including where more earthquakes are likely to happen or the potential environmental impact of radiation in the air and water that was released from the Fukushima Dai-Ichi nuclear power plant. The magnitude-7.1 aftershock that struck Japan today at 10:30 a.m. Eastern time, about 215 miles northeast of Tokyo, underscores the need to run these simulations.
