Analysis of Structural Damage and Disaster Management Resulting from Earthquakes in Cianjur

Abstract

The earthquake that occurred in the Cianjur area, West Java on Monday 21 November 2022 at 13.21 WIB resulted in 635 fatalities and 56,000 houses that were damaged. Therefore, it is necessary to conduct an assessment and mitigation of the structural damage buildings and the impact of earthquakes. From the results of the assessment carried out in the area where the earthquake occurred, it was found that many houses and public facility buildings still did not meet the requirements for earthquake-resistant buildings, especially in the use of concrete materials, main reinforcement and stirrups in columns, beams, foundations and beam-column joint. The amount of damage to buildings that occurred as a result of the buildings standing did not have a strong column-weak beam planning concept. This can be seen from the inability of the column to withstand/ carry the working load which causes the column to collapse and damage. Therefore, it is very necessary to pay attention to building planning in Disaster Prone Areas (KRB) in accordance with earthquake resistant building regulations SNI 1726:2019 and SNI 2847:2019. In addition, post-disaster management measures should include the assessment of survivors’ health conditions (psychological support and trauma healing), the operational control of healthcare services, the treatment of injured victims and the management of fatalities, the prevention of communicable diseases, the provision of adequate nutrition, the strengthening of information systems and coordination mechanisms, the improvement of sanitation facilities (installation and supply of clean water) and latrines, as well as the deployment of medical personnel and logistics assistance  need to be improved and coordinated well after the earthquake.
