Magnitude 7.7 Earthquake Strikes Off Indonesia's Coast, Killing at Least 5

A powerful magnitude 7.7 earthquake struck off the coast of Indonesia early Saturday morning, collapsing buildings, sending panicked residents fleeing into the streets, and killing at least five people in a region long accustomed to the ground shifting beneath it.

When and Where It Happened

The U.S. Geological Survey recorded the quake at 5:58 a.m. local time, striking Indonesia’s Flores region at a shallow depth of 10 kilometers. Its epicenter sat roughly 68 kilometers north-northwest of the city of Ende, in East Nusa Tenggara province — a part of the country that sits directly on the Pacific “Ring of Fire,” where the majority of the world’s earthquakes occur. The initial shock was followed by more than a dozen aftershocks, including one measuring magnitude 6.1.

A Rising Toll and a Region Left in the Dark

East Nusa Tenggara’s police chief, Rudi Darmoko, said preliminary reports point to two deaths in Sikka Regency and three more in Manggarai Regency, though he cautioned that widespread power outages have disrupted communication and slowed the flow of information from affected areas. Search and rescue teams are still working to confirm the full scope of casualties and damage as reports continue to come in.

Roughly 500,000 people were exposed to strong or severe shaking strong enough to cause serious damage to poorly built structures, according to USGS ground-motion estimates. Hospitals in the region evacuated patients as a precaution, with footage showing staff moving beds, IV stands, and oxygen equipment outdoors to set up temporary treatment areas.

Scenes From Flores Island

The quake was felt across much of Flores, with residents describing chaotic scenes as buildings buckled around them. Yohanna Embu, a resident of Sikka regency, described the waiting room at the port terminal in Maumere collapsing as people ran for higher ground.

At St. Peter Major Seminary in Sikka, students and nuns attending morning Mass fled in panic as the roof of an assembly hall gave way. The Rev. Guidelbertus Tanga, the seminary’s rector, said at least one priest broke his leg jumping from the second floor of a building during the shaking. Damage and panic were also reported further afield, in the city of Bima in neighboring West Nusa Tenggara province, and in parts of southern Sulawesi island.

A Tsunami Warning, Then Relief

Indonesia’s Meteorology, Climatology and Geophysics Agency issued a tsunami warning immediately after the quake for East Nusa Tenggara, West Nusa Tenggara, South Sulawesi, and Southeast Sulawesi provinces, urging residents along the coast to move away from beaches and rivers and head to higher ground. The warning was lifted several hours later once monitoring showed no significant sea-level changes that would threaten coastal communities.

Indonesia’s Long History With the Ring of Fire

Indonesia is a vast archipelago of more than 17,000 islands, and its position along the Ring of Fire makes it one of the most seismically active places on Earth. Flores itself has been the site of tragedy before — a 1992 earthquake and tsunami killed roughly 2,500 people on the island. More recently, a 2018 quake near Palu triggered soil liquefaction that swallowed entire neighborhoods and killed more than 4,400 people, while the catastrophic 2004 Indian Ocean earthquake and tsunami, centered off Sumatra, killed an estimated 230,000 people across a dozen countries.

Why It Matters

Saturday’s earthquake is a reminder of how quickly disaster can unfold in a region where millions of people live in close proximity to active fault lines. With communication still down in parts of East Nusa Tenggara and search efforts ongoing, officials caution that the current death toll may not be final. As power is restored and rescue teams reach harder-hit areas, a clearer picture of the damage — and the human cost — is expected to emerge over the coming days.
