2012Damage was limited to glazing and very minor cladding damage on the government building.Damage to glazing and non-structural RC-infill panels was common at the apartment block,which was inundated to the 3 rd storey, while debris impact had damaged a steel-framevehicle parking elevator (EEFIT, 2011). People were trapped in this building until March 12 thdue to silt blocking the stairwells (EEFIT, 2011). The owner of the Hotel Horaikan atUnosumai directed guests to high ground behind the hotel, rather than staying in thebuilding. The hotel suffered non-structural damage at the ground floor only, and at the timeof our visit the hotel was being refurbished internally.There were plans for further tsunami evacuation buildings and towers close to the KamaishiPort, but these had not yet been constructed.Figure 34 Designated evacuation locations in Kamaishi City.
