Japan earthquake appears to increase quake risk elsewhere in the country: study

Japan earthquake appears to increase quake risk elsewhere in the country: study: "Japan's recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the build up of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say."
