Public Warnings During Earthquake Disaster

本项目侧重于1989年10月17日洛马普列塔地震的教训。关于有效传播公共灾害警报的现有知识主要依赖于影响前警报的数据库。在影响后灾害紧急时期，关于公众听到、感知和响应警告的决定因素和过程的知识存在差距。本研究是对洛马普里塔地震后公众对余震预警的认知和反应的研究。邮件问卷将收集代表旧金山（媒体丰富环境）和圣克鲁斯（媒体稀疏环境）800户家庭的相关数据。将确定公众在灾难发生后立即听到、感知和响应警告的过程和决定因素。地震后快速反应的实地调查表明，还有很多东西需要学习。这次地震也许是第一次提供了对这一主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.
