Overview

Randomized trial evaluates earthquake losses in Indonesian regencies, suggesting a new framework for assessment.

Key Points

  • The aim is to develop a comprehensive framework to evaluate earthquake impacts in Indonesia using two new metrics.
  • Utilized Grey Relational Analysis, Equal Weights, Entropy Weight Method, and CRITIC across 28 regencies and municipalities.
  • Assessed impacts from earthquakes between 2016 and 2022.
  • The 2018 earthquake resulted in the highest losses, with Palu Municipality and Donggala Regency having consistently high SSI values.
  • Sigi Regency, Donggala Regency, and Palu Municipality identified as the most affected areas by the SII.
  • Areas like Sigi and North Lombok showed high severity and impact, whereas Garut, Ciamis, and Cilacap were less affected.
