Loma Prieta Earthquake Citizen Survey: Santa Cruz, 1990 (M1095B)

The purpose of this study was to assess public response to the Loma Prieta earthquake emergency. Investigators wanted to be able to describe the public's experience with the earthquake and damage, and what the public did and did not do in response to the emergency. In addition, wanted to be able to explain why there were differences in how and why people responded; defined as an altruistic collective emergency response. The hypothesis of the investigators was that citizen involvement in response to the Loma Prieta earthquake emergency would 1) result as a consequence of victimization; 2) increase as a consequence of factors such as pre-event hazard salience and experience; 3) and would not be affected by nor vary by basic structural characteristics such as age, ethnicity, gender, socioeconomic status, community integration, or role membership. Two populations were selected for study: San Francisco (n=734) and Santa Cruz (n=918) counties. Questions covered the types of damage experienced, injuries, exposure to media, emergency response activities, community integration, other earthquake experiences, household roles and responsibilities, and socioeconomic status.本研究旨在评估公众对洛马普列塔地震（Loma Prieta earthquake）应急事件的反应。研究者希望能够描述公众在地震及灾情中的经历，以及公众在应急响应过程中的作为与不作为；此外，还希望能够解释人们在响应方式与动因上存在差异的原因，这类差异被定义为利他性集体应急响应。研究者提出的研究假设为，民众参与洛马普列塔地震应急响应的情况将满足以下三点：1） 因自身受灾经历而产生；2） 随震前灾害显著性、过往灾害经历等因素的影响而增强；3） 不受年龄、族裔、性别、社会经济地位、社区融入度或角色身份等基本结构特征的影响，亦不会随这些特征产生变化。本研究选取了两个研究群体：旧金山县（样本量n=734）与圣克鲁斯县（样本量n=918）。调研问题涵盖所经历的灾害类型、人员受伤情况、媒体接触情况、应急响应活动、社区融入度、其他地震经历、家庭角色与职责，以及社会经济地位。
