Where Flores Meets the Ocean, A Temporary Warning Sends Families Inland Before the Water Returns Quietly

The ocean can appear strangely calm after a warning has been issued. Along Flores, that contrast unfolded after a powerful offshore earthquake sent residents away from the coastline. For a period of several hours, the sea became something to watch carefully, its quiet surface carrying the possibility of movement that could not yet be ruled out.

The earthquake struck early Saturday near Nagekeo Regency in East Nusa Tenggara. BNPB said the magnitude 7.7 quake was centered in the sea approximately 38 kilometers northeast of Mbay, at a depth of about 15 kilometers. (bnpb.go.id)

Because the earthquake occurred offshore, Indonesian authorities issued a tsunami warning for potentially affected coastal areas. Residents were advised to move away from the shoreline and toward safer locations while monitoring systems assessed whether significant waves were developing.

The warning was eventually lifted. Reuters reported that tsunami waves remained below one meter and that authorities withdrew the alert after approximately three hours when there was no indication of a continuing significant threat to coastal communities. (reuters.com)

For those who evacuated, the experience was shaped by uncertainty rather than certainty. A tsunami warning is designed to act before danger becomes visible, meaning residents must respond to information while the situation is still developing. Moving inland or toward higher ground can therefore become an essential precaution.

The earthquake itself proved more damaging than the tsunami threat. At least 38 people were reported dead, while homes and infrastructure were damaged across parts of Flores. Landslides also blocked roads, making some communities difficult to reach and slowing emergency operations. (reuters.com)

More than 2,000 residents evacuated affected areas, according to Reuters. Some communities experienced power outages and communication disruptions, creating additional difficulties for residents trying to contact relatives or receive information about the condition of roads and nearby areas.

The temporary tsunami warning demonstrated the importance of monitoring systems in an earthquake-prone country. Indonesia sits along the Pacific Ring of Fire, where tectonic activity regularly produces earthquakes and volcanic eruptions. Early warnings can provide valuable time for coastal communities to move away from danger when an offshore earthquake creates the possibility of tsunami waves.

But warnings are only one part of the response. After the alert was lifted, emergency crews still had to deal with collapsed buildings, casualties, damaged roads, landslides, and displaced families. The coast could return to calm while the inland recovery effort continued.

For Flores residents, the end of the tsunami warning marked only one moment in a much longer emergency. Authorities continue assessing the earthquake's impact and restoring access to affected areas. The sea has remained below dangerous tsunami levels, but the damage on land continues to shape the days ahead.
