On Sunday night on 19-August-2018 at 10:56 p.m. local time, the Tectonic Earthquake happened again with magnitude 7.0 SR (BMKG), then revised to be 6.9 SR. The M6.9 earthquake occurred several hours after the M6.3 earthquake occurred in the East Lomboh region. With a series of earthquake events some time in close proximity, it can be concluded that the earthquake event has a close relationship. The rock fracture zones that occur are still occurring in a Faulting Flores system (Flores Thrust Fault).
By paying attention to the character of the source of the earthquake mechanism, location and depth and time span adjacent between the earthquake M7.0 (05082018) and M6.9 (19082018), the activity of these two earthquakes is called "Multi Earthquake" (Multiplet Earthquakes). Based on BMKG's information, the "New Earthquake" since last night, until now at 7:00 a.m., has awakened 88 times aftershocks, 8 aftershocks have significant strength and perceived shocks by the community.
The areas that most affected the earthquake included East Lombok Regency, North Lombok Regency, Central Lombok Regency, and Mataram City. Based on Maipark Catastrophe simulation Modeling economic losses (damage to residential houses) is estimated at + 300-700 billion Rupiah. For insurance exposure data in affected districts of 4.1 Trillion rupiah, estimated insurance losses through modeling for the earthquake amounted to + 10-100 billion Rupiah. MAIPARK is still monitoring developments and official reports from BNPB regarding the damage caused by the earthquake.
