On 17 October 1989, an earthquake measuring 7.1 on the Richter scale struck the San Francisco Bay Area, causing the collapse of .76 miles of a double-decker roadway (known as the Cypress Street Viaduct), resulting in the death of 42 people. A study examined the effects of rescue work at 6 and 20 months after the event, among 42 people including: military pararescuers, firefighters, transportation workers, and coroner-investigators. The researcher explored the rescuers' motivations, actions, coping strategies, interactions, and understanding of their responses to the event, as well as the practical wisdom each acquired. This article focuses on the 6-month data, and reports the specific work meanings and practices that shaped forms of involvement, issues of stress, and sources of coping that influenced the experience of rescue work in this disaster.
