To examine the relation between seismic intensity(JMA) and hospitals' damages, composed of interruption of medical functions, daily life functions, equipment as well as building damages including nonstructural elements, questionnaire surveys were conducted for the 2003 Off Miyagi Prefecture Earthquake, the 2003 Northern Miyagi Prefecture Earthquake and the 2003 Tokachi-oki Earthquake. Hospitals near the earthquake observation stations were selected for the surveys. Meanwhile, to compare damages of hospitals with those in other common facilities, many public facilities, such as ward offices and schools, were also investigated. Results are concluded as follows. a) Damage ratios of many building damages of hospitals are higher than common facilities, and increase with older hospitals built before 1980. b) Many building damages begin to take place at a seismic intensity 5+, and increase rapidly over seismic intensity 6. c) Damages of many equipment items related to daily life functions begin to take place at a seismic intensity 6. d) Many medical instruments show no physical damages till seismic intensity 5+, but some may be unable to perform normally as early as at a seismic intensity 4 due to interruption of daily life functions. e) Interruption of most medical functions starts at a seismic intensity 6.
