Ishinomaki (Miyagi): Damaged tanks at Port of Ishinomaki. Displaced or overturned steel tanks were common in tsunami inundated areas.

Minami Sanriku (Miyagi): The seismically retrofitted hospital (see external inverted "V" braced frames) survived three minutes of strong ground shaking, followed by 15-meter tsunami. The four story structure was barely tall enough to serve as tsunami vertical evacuation shelter.

Ishinomaki (Miyagi): Low-profile bridges tended to survive the tsunami forces, though extensive debris impact damage was evident.

Sendai Airport (Miyagi): A cargo warehouse was damaged by fire that initiated from a vehicle battery. Tsunami displaced vehicles were a common occurrence.

Minami Sanriku (Miyagi): The three-story disaster prevention building served to announce tsunami warnings. The structure was overtopped by tsunami. Only 10 of 39 roof evacuees survived.

Port of Sendai: Tsunami erosion behind a ship berth and a fuel storage facility (background) damaged by fire.

Chiba (Tokyo Metro): Soil liquefaction induced buoyant forces on a pipeline beneath a sidewalk.

Tokyo: Seismic retrofits of elevated railways and highways (column steel jackets) were a common sight in the region.

Uraysu (Tokyo area): The community was developed on reclaimed landfill along Tokyo Bay and experienced extensive soil liquefaction (see uplifted sewer manholes). The hotel in the background was developed on a seismically improved site which performed well.

Sendai (Miyagi): Example of a seismic retrofit of an older building in Sendai. The retrofit program (following the 1978 earthquake) was a success during the 2011 earthquake.
