Coseismic Subsidence

The 2011 Tohoku-oki earthquake caused large eastward displacement and subsidence along the Pacific coast of northeastern Japan. This earthquake partly solved a well-known paradox holding that sense and rate of deformation differ greatly between geologic and geodetic estimates. A paradox remains, however, in explaining long-term uplift along the Pacific coast on a geologic time-scale. Geodetic data show that coastal subsidence continued at a nearly constant rate of ∼5 mm/yr with small fluctuations associated with M7-8 interplate earthquakes for ∼120 years before the Tohoku-oki earthquake. In an area near the Oshika Peninsula where coseismic subsidence is largest, extrapolation of a logarithmic function fitting observed postseismic deformation suggests that coseismic subsidence may be compensated for by the postseismic uplift for several decades but it is difficult to expect the postseismic uplift exceeding 2 meters, so it is implausible that the observed rapid subsidence continued throughout an entire interseismic period in a great megathrust earthquake cycle. We propose a hypothetical model in which the sense of vertical deformation changes from uplift to subsidence during the interseismic period. Using simple elastic dislocation theory, this model is explained by the shallow coupled part of a plate interface in an early interseismic period and the deep coupled part of a late interseismic period.

This paper analyzes how the Japanese government has responded to the March 11, 2011, Great East Japan Earthquake and subsequent tsunamis that devastated cities and towns along the Pacific coast of northeastern Japan claiming many precious lives and causing extremely extensive destruction. The resilience of a society depends largely on how it identifies existing gaps, how it addresses them in the recovery process, and how it integrates solutions in the existing disastermanagement system as a result. From such a perspective, this paper examines the government’s response to the disaster for approximately the first one year following it by taking stock of progress made versus the priorities of the Hyogo Framework for Action 2005-2015.

We collected data on the March 11, 2011, Great East Japan Earthquake by surveying web sites related to power failures during 2011 off the Pacific coast of Tohoku (northeastern Japan) and, in addition, by interviewing local government sectors and Tokyo Electric Power Company (TEPCO) branch office personnel. We quantify two damage ratios for power failures for subject municipalities defined by the ratio of the number of affected households and houses in a city to the number of related households and houses. This revealed the dependence of damage ratios on seismic intensities induced in subject municipalities. Damage functions related to power failures are then developed.
