Aftershocks along Fukushima, Ibaraki borders may take over 100 years to subside
Mainichi
May 15, 2012

It may take at least 100 years before aftershocks from the March 11, 2011 quake along the boundaries of Fukushima and Ibaraki prefectures subside, a recent study reveals. [...]

Based on [associate professor at Kyoto University's Disaster Prevention Research Institute Shinji Toda's] initial calculations, Toda estimated that it will take more than 800 years for aftershocks to subside in areas along the borders of Fukushima and Tochigi prefectures, regions relatively close to the damaged Fukushima No. 1 Nuclear Power Plant, where active seismic activities still continue.

However, anticipating that plates [...] will gradually adhere with time [...] Toda concluded that the most likely period of time until aftershocks subside in the two prefectures is “at least 100 years.” [...]

“It is important that people stay alert knowing that aftershocks following a major earthquake last for a long period of time,” Toda says. “Since active aftershocks may also affect volcanic activity in the area, it is important to keep observing the situation.”
