Although data are limited, field reports indicate that reported violence against women increases in communities hit by environmental disasters. Seventy-seven Canadian and U.S. domestic violence programs participated in a study of organizational readiness, impact, and response employing a mail survey and open-ended telephone interviewing. Low levels of in-house emergency preparedness were found, but also strong interest in increasing disaster readiness. Those programs most severely impacted by disasters reported increased service demands, as long as 1 year after the event, and decreased organizational resources. Strategies are suggested for more fully engaging women's services in community-based disaster mitigation, planning, and response.
