A Global Earthquake Building Damage and Casualty Database
This chapter presents a preliminary overview of the Cambridge University Earthquake Damage Database (CUEDD) now the Cambridge Earthquake Impact Database (CEQID) with emphasis on its human casualty component. CUEDD is based on earthquake damage data assembled by the Martin Centre at Cambridge University since 1980, complemented by other more-recently published and some unpublished data. The database through its organised, expandable and web-accessible format, summarizes information on worldwide post-earthquake building damage surveys which have been carried out since the 1960s (www.ceqid.org). Currently it contains data on the performance of more than 1.3 million individual buildings, in 600 surveys following 50 separate earthquakes. The database provides total recorded casualties (deaths, seriously and moderately injured), and casualty rates as a proportion of population with definitions of injury levels used, and information on dominant types of injury, age groups affected, etc. It also provides geographically disaggregated data where possible, and associates them with tables and GIS maps. Sources of information on other aspects of human casualty information (epidemiological studies, health care impacts, etc.) are provided. Analytical tools enable relationships between casualty rates, building classes and ground motion parameters to be determined.

CUEDD has been developed by Cambridge Architectural Research Ltd. The project team has included Robin Spence, Antonios Pomonis, Emily So, Keiko Saito, Victoria Lee, Hermione Tuck, Aiko Furukawa, Janet Owers and Susanna Jenkins. CAR has worked in collaboration with the PAGER team at US Geological Survey, Golden Colorado, David Wald and Kishor Jaiswal. The database and website design were by Simon Ruffle and Vicky Smith of Stride Design. Financial support for the development of CUEDD has been provided by the Coburn Foundation. Several damage surveys have been sourced from the personal archive of Andrew Coburn; other contributions have come from Antonios Pomonis, the EU Centre, Pavia, and Jim Cousins of GNS, New Zealand.
