Public Warnings During Earthquake Disaster

这个项目的重点是可以从1989年10月17日洛马普里塔地震中吸取的教训。关于有效传播公共灾害警报的现有知识在很大程度上依赖于影响前警报的数据库。关于公众在灾害后紧急时期听到、感知和回应警告的决定因素和程序方面的知识存在差距。这项研究是对洛马普里塔地震后公众对余震警报的感知和反应的研究。邮寄问卷将收集代表旧金山(媒体丰富的环境)和圣克鲁斯(媒体稀少的环境)的800个家庭的相关数据。将确定公众在灾难发生后立即听到、感知和回应警告的过程和决定因素。这次地震后的快速反应实地研究表明，还有很多东西需要学习。这次地震提供了一个可能是第一次对这个话题进行系统研究的机会。

This project focuses upon lessons that can be learned from the October 17, 1989 Loma Prieta Earthquake. Existing knowledge about the effective communication of public disaster warnings largely rests on a data base of pre-impact warnings. A gap exists regarding knowledge about the determinants and process whereby the public hears, perceives and responds to warnings during the post-impact disaster emergency period. This research is a study of public perception and response to aftershock warnings following the Loma Prieta Earthquake. Mail questionnaires will collect relevant data on 800 households representing San Francisco (a media rich environment) and Santa Cruz (a media sparse environment) households. The process and determinants of that process whereby the public hears, perceives and responds to warnings during the immediate aftermath of a disaster will be determined. Quick-response field research after this quake suggest that there is much to be learned. This quake provides an opportunity to conduct a systematic study on this topic for perhaps the first time.
