The Taal Volcano eruption was one of the most severe disasters in the Philippines in 2020. The purpose of this study was to determine factors affecting response action of the 2020 Taal Volcano eruption among Filipinos in Luzon, Philippines. Several factors including asset damage, eruption characteristics, disaster experience, socio-demographic characteristics, evacuation characteristics, and perceived severity were analyzed simultaneously by utilizing a structural equation modelling (SEM) approach. A total of 501 respondents were collected from Filipinos who lived in Batangas (411 respondents), Manila (82 respondents), and Pampanga (8 respondents). SEM showed that asset damage had the highest effect on perceived severity (β: 0.68; p=0.001), followed by eruption characteristics (β: 0.49; p=0.001) and evacuation characteristics (β: 0.25; p=0.012) while disaster experience and socio-demographic characteristics had no significant effects on perceived severity. This study is the first study that analyzes the perceived severity of the 2020 Taal Volcano eruption. The findings would be very beneficial for researchers and policymakers to reduce the perceived severity of the eruption. Finally, the SEM construct can be applied and extended to determine factors affecting perceived severity of volcanic eruptions in other countries.

塔尔火山喷发是 2020 年菲律宾最严重的灾害之一。本研究的目的是确定影响菲律宾吕宋岛 2020 年塔尔火山喷发响应行动的因素。利用结构方程模型 (SEM) 方法同时分析了包括资产损坏、喷发特征、灾难经历、社会人口特征、疏散特征和感知严重程度在内的几个因素。共有 501 名受访者来自居住在八打雁（411 名受访者）、马尼拉（82 名受访者）和邦板牙（8 名受访者）的菲律宾人。SEM 显示资产损坏对感知严重程度的影响最大（β：0.68；p=0.001），其次是喷发特征（β：0.49；p=0.001）和疏散特征（β：0.25；p=0）。012) 而灾害经历和社会人口特征对感知的严重性没有显着影响。这项研究是第一项分析 2020 年塔尔火山喷发严重程度的研究。这些发现对于研究人员和政策制定者来说非常有益，可以降低人们对火山喷发严重程度的认知。最后，可以应用和扩展 SEM 结构来确定影响其他国家火山喷发严重程度的因素。
