Surabaya resilience index for potential earthquakes: An institutional perspective

The earthquake map released by the Indonesian National Earthquake Board in 2017 categorized Surabaya as prone to earthquakes caused by the Kendeng Thrust. In order to anticipate this new threat, this study assesses Surabaya's current earthquake and disaster resiliency. Despite being one of Indonesia's most successful cities, receiving many honours nationally and internationally, Surabaya's institutions still have a mediocre performance in terms of resiliency, with middle-to-high performance for resilience to general disasters and middle-to-low resilience to potential earthquakes. Surabaya has an average performance compared to 19 other cities around the Asia-Pacific; however, Surabaya scores the lowest for mainstreaming potential for earthquakes in public planning indicating that the city has not anticipated this new threat. Thus, Surabaya needs to enhance its resiliency in the near future due to the unidentified risk, response and emergency-centred actions, and limited public documents considering the risk.
