The death toll from the 7.7-magnitude earthquake that struck Indonesia's Flores region on 15 August has climbed to 100, with 1,603 people injured and more than 180,000 still displaced, the National Disaster Management Agency (BNPB) confirmed on Monday. The disaster, centred 36 km northeast of Mbay in East Nusa Tenggara province at a depth of 15 km, continues to strain emergency response capacity across the affected region.

Rising Death Toll and Aftershock Activity

BNPB chief Suharyanto said many of the additional fatalities were individuals who had sustained serious injuries during the initial quake and subsequently died while undergoing treatment. He noted that 6,409 aftershocks have been recorded since the main tremor, including 33 with a magnitude of at least 5.0. The strongest aftershock measured 6.2. On Sunday at 2120 GMT, a further 5.3-magnitude quake struck the Flores region, according to the GFZ German Research Centre for Geosciences, with its epicentre at a depth of 10 km.

Infrastructure Damage and Displaced Residents

The earthquake caused significant damage to public infrastructure. According to BNPB, 87 educational facilities, 18 health facilities, five places of worship, and six government offices were damaged. Over 180,000 displaced residents — including those in remote areas — are receiving government aid, though access to outlying communities remains a logistical challenge.

Authorities Counter Misinformation

Suharyanto urged residents not to act on false information circulating about stronger impending earthquakes or a potential tsunami. He said aftershock activity has shown a declining trend in recent days, though authorities cautioned that tremors could persist for another three to four weeks, with frequency and intensity expected to gradually decrease. The Meteorology, Climatology and Geophysics Agency (BMKG) had issued a tsunami warning immediately following the initial quake, which was later lifted.

Indonesia's Seismic Vulnerability

Indonesia sits on the Pacific 'Ring of Fire' and is home to more than 120 active volcanoes, making it one of the world's most seismically and volcanically active nations. The country has a long history of catastrophic earthquakes — most notably a 9.1-magnitude tremor in 2004 off the coast of Sumatra, which triggered a tsunami that killed approximately 220,000 people across the region, including around 170,000 in Indonesia alone. This context underscores why the Flores quake, though far smaller in scale, has prompted a large-scale emergency response.

Relief Operations and What Comes Next

Government agencies are continuing to deliver humanitarian aid across affected districts. With aftershocks still occurring and tens of thousands yet to return home, the focus now shifts to longer-term rehabilitation of damaged infrastructure and housing. The coming weeks will be critical in determining the full scope of the disaster's human and economic cost.
