The lack of studies on Filipinos preparedness in natural calamities such as earthquakes, specifically “The Big One”, posed the necessity for researchers to assess the preparedness and disaster mitigation. This study aimed to assess the driving factors that significantly influence the intention to prepare among Filipinos for mitigation of The Big One earthquake. With the integration of Protection Motivation Theory and Extended Theory of Planned Behavior, the study considered 727 valid responses to measure the intention to prepare. Eight latent were measured namely: (1) perceived vulnerability, (2) perceived severity, (3) subjective norm, (4) perceived behavioral control, (5) attitude, (6) media, (7) understanding of The Big One, and (8) intention to prepare. By utilizing Structural Equation Modelling, it is found out that Media, Attitude, Perceived Severity and Subjective Norm are all key factors affecting the intention of the people to prepare for the Big One. Moreover, it was also found out that the Understanding of the Big One has an indirect effect on the intention to prepare. The findings of the study can be utilized by the government to make Filipinos for conducting preparedness and mitigation practices. Finally, the model construct of the study could also be utilized to evaluate other types of natural disasters worldwide.

缺乏对菲律宾人在地震等自然灾害中的准备情况的研究，特别是“大灾难”，这使得研究人员有必要评估准备和减灾情况。本研究旨在评估显着影响菲律宾人为减轻大地震做准备的意愿的驱动因素。结合保护动机理论和计划行为扩展理论，该研究考虑了727个有效反应来衡量准备意图。测量了八个潜在因素，即：（1）感知的脆弱性，（2）感知的严重性，（3）主观规范，（4）感知的行为控制，（5）态度，（6）媒体，（7）对大人物的理解， （八）准备意向。通过利用结构方程建模，发现媒体、态度、感知严重性和主观规范都是影响人们为大事件做准备的意愿的关键因素。此外，还发现对大一的理解对准备意图有间接影响。政府可以利用这项研究的结果让菲律宾人进行准备和缓解措施。最后，该研究的模型构建也可用于评估全球其他类型的自然灾害。政府可以利用这项研究的结果让菲律宾人进行准备和缓解措施。最后，该研究的模型构建也可用于评估全球其他类型的自然灾害。政府可以利用这项研究的结果让菲律宾人进行准备和缓解措施。最后，该研究的模型构建也可用于评估全球其他类型的自然灾害。
