On April 10th, 2021, 3296 houses suffered light damage, 1964 houses suffered moderate damage, and 1552 houses suffered severe damage due to the earthquake that occurred in Malang, Indonesia. The iMPact on public facilities included 203 damaged schools, 16 damaged health facilities, 171 damaged places of worship, and 40 other damaged public facilities. Most of the damaged buildings were non-engineering buildings with various types of damage. In Pacitan Regency, there are many low-rise to medium-rise non-engineering buildings. In addition, Pacitan Regency has a coastline that is part of the Indonesian Ocean and is located very close to the subduction zone between the Indo-Australia plate and the Eurasian plate. The main potential sources of earthquake and tsunami events in this region are thrust systems. Seismic fragility curves play a pivotal role in the assessment of the comprehensive vulnerability of civil infrastructure to prospective seismic events, as well as in the anticipation of the consequential socioeconomic repercussions. This paper presents an analysis of the fragility of non-engineering buildings and estimates of their collapse using the finite element method. Seismic fragility analysis produces fragility curves that show the probability of structure damage under various damage conditions. [ABSTRACT FROM AUTHOR]
