Abstract

The earthquake that occurred on February 25th, 2022 (6.2 M) and the aftershock in the West Pasaman Regency, West Sumatra Province has caused damages to infrastructure and community settlements. One of those affected by the Pasaman Earthquake 2022 are public buildings. To determine the level of public building damage, an assessment should be carried out before reoccupying the buildings. In this study, a rapid assessment of damaged public buildings was conducted after the Pasaman Earthquake by the Disaster Study Center of Andalas University team. The assessed buildings include the buildings of Balerong Hall, Ibnu Sina Hospital, Grand Mosque, Population and Civil Registration Agency (Disdukcapil) office, Regional Public Hospital, and Elementary School (SDN) 22 of Talamau. The results of the assessment show that in general, these public buildings have non-structural damages, such as cracks in the walls and ceiling crashes from their positions. Meanwhile, in the buildings of Elementary School (SDN) 22 Talamau, Grand Mosque, and Disdukcapil, it is found that there are some structural damages observed, such as cracks on the columns. The main factor causing the damage is the low quality of the concrete in the columns. Recommendations for repairing the damaged building are also discussed in this study.
