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.

This paper reviews approximately the first nine months of the Japanese Government’s response to the March 11, 2011 Great East Japan Earthquake and Tsunami that hit the Pacific coast of Northeastern Japan and devastated many coastal communities. By examining various forms of governmentwide initiatives i.e., the Extreme Disaster Management Headquarters, the Reconstruction Design Council, the Headquarters for Reconstruction, the Reconstruction Agency and the Central Disaster Management Council, this paper tries to clarify the specific functions and main achievements of those institutions It also highlights the main features of the Japanese Government’s disaster response and underlies major changes from past practices due to the unprecedented scale and nature of the disaster.

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.

Reproduction and longevity of Aurelia labiata in Roscoe Bay, a small bay on the Pacific coast of Canada

Observation Period

Reproduction by the moon jelly, Aurelia labiata, was observed in a small bay on the west coast of Canada. The bay is located in an area isolated from human contact except in the summer, is sheltered from wind and wave action by mountain ridges, and has limited tidal flushing due to a gravel bar at the entrance that dries at lower low water. Planulae appeared in brood sacs beginning in October and November. The planulae were shed by the end of March and ephyrae emerged in June. Juvenile medusae were estimated to constitute about 30—40% of medusae in the bay in each of the two years of this study. Medusae remained in the bay throughout the year. There was no major visible mortality in the adult population during the two year observation period. Medusae appear to be lost from the bay as a result of tidal flushing. It is argued that in Roscoe Bay Aurelia labiata medusae live for more than one year and that up to 40% of the adult medusae may be two years of age or older.
