M7.7 Earthquake Strikes East Nusa Tenggara; Tsunami Warning Lifted but Aftershocks Expected
Indonesia's meteorological agency (BMKG) confirmed that the magnitude 7.7 earthquake that struck East Nusa Tenggara (NTT) early Saturday was caused by the Flores back-arc thrust fault. The tsunami warning was lifted at 7:30 AM local time, but BMKG warned the fault could still produce quakes up to magnitude 7.8-7.9 and is closely monitoring aftershock activity.
BMKG's Director of Earthquake and Tsunami, Wijayanto, explained at a press conference in Jakarta on Saturday that the magnitude 7.7 earthquake that struck East Nusa Tenggara (NTT) in the early hours was caused by the Flores back-arc thrust fault. This fault system has the potential to generate earthquakes up to magnitude 7.8-7.9, and a similar mechanism produced a devastating M7.5 quake in 1992. "It's been more than 30 years since then, and it has happened again," Wijayanto said, adding that BMKG will continue monitoring aftershock activity.
BMKG lifted the tsunami warning at 7:30 AM local time (WIB), though it will continue monitoring sea level readings at coastal stations.
The affected NTT region—which includes Flores Island and Komodo National Park, popular destinations for travelers based in Bali—may see disruptions to ferry and flight schedules as well as Komodo tours. No major damage has been reported in Bali itself so far, but travelers heading to NTT should stay updated given the possibility of aftershocks or renewed tsunami advisories.
Things to Consider
If you are traveling to or currently in the NTT region (Flores, Komodo Islands, etc.), regularly check BMKG's official website or app for the latest earthquake and tsunami updates. If you feel strong shaking while near the coast, move to higher ground or inland immediately regardless of whether a tsunami warning has been issued. Confirm ferry and flight schedules before departure, as service disruptions are possible. Keep your passport and essential documents in an easily accessible location. Those staying on Bali's main island face minimal direct risk but should still monitor aftershock updates.
