Monday, February 21, 2022, at 20.35 WITA an earthquake with a magnitude of 5.8M (BMKG) or 5.8mww (USGS), the epicenter of the earthquake was 60 kilometers northeast of Ruteng at a depth of 10 kilometers. The earthquake was generated from the Flores Back-Arc Thrust System, which seismically has the potential to cause a 7.5M earthquake.
Based on the MCM1 simulation, the area affected by intensity VI (MMI) is Kec. Lamba Leda & Kec. sambi Rampas in Manggarai Regency. Meanwhile the district. Cibal, District. Reok (Kabupaten Manggarai) and Kec. Pocoranaka (East Manggarai Regency) experienced an earthquake intensity at V MMI.
The area between Manggarai and Flores was also identified as a seismic gap. The most recent major earthquake in the region occurred on April 14, 1855. Since then, the region has been relatively passive. According to the MAIPARK database (from earthquake insurance policy submissions), insurance exposure is very low. The total affected portfolio in the V-VI MMI is IDR 8.51 billion rupiah (13 risks).
