Magnitude 5.9 Earthquake Strikes East of Lospalos, Timor-Leste

A magnitude 5.9 earthquake struck this morning at a point roughly 253 kilometers east-northeast of Lospalos, Timor-Leste, according to the U.S. Geological Survey. The quake originated deep underground — about 112 kilometers below the surface — in the seismically active Banda Sea region, where the Australian tectonic plate slides beneath the Eurasian plate. This area produces earthquakes regularly, and this event fits that pattern.

Because of the quake’s depth, shaking at the surface would have been noticeably weaker than a shallow quake of the same magnitude. People in eastern Timor-Leste, including Lospalos and surrounding communities, may have felt a gentle to moderate rolling or swaying sensation lasting several seconds. Light shaking may also have been noticed on nearby islands in eastern Indonesia, including parts of Maluku province. Reports of shaking at this magnitude and depth typically describe rattling windows, swinging light fixtures, and movement felt by people indoors on upper floors.

Who is affected: primarily residents of eastern Timor-Leste and islands in the southern Banda Sea. At this magnitude and depth, significant structural damage is unlikely, though minor effects — cracked plaster, items knocked off shelves — are possible in older or lightly built structures closest to the epicenter region. No serious damage or injuries have been reported at this time.

What to keep in mind

There are three practical points for readers in the region. First, aftershocks are possible after any magnitude 5+ earthquake, though deep quakes like this one tend to produce fewer and weaker aftershocks than shallow ones. If you feel shaking again, drop to the ground, take cover under sturdy furniture, and hold on. Second, check your home for any new cracks in walls or foundations, especially if you are in eastern Timor-Leste — deep quakes rarely cause major damage, but it is worth a quick walk-around. Third, an earthquake of this size at this depth is not expected to generate a tsunami. Tsunamis are typically produced by large, shallow earthquakes that displace the seafloor; a 112-kilometer-deep event does not move the sea floor in a way that pushes water toward coastlines.

The Banda Sea region experiences earthquakes of this size several times a year, and most pass without incident. Staying aware of local authorities’ guidance and having a basic household plan — knowing safe spots in your home and keeping an emergency kit with water and supplies — is sensible preparation for anyone living in this seismically active part of the world.

Data for this alert comes from the U.S. Geological Survey (USGS) earthquake monitoring program.

Frequently Asked Questions

Was the earthquake felt in Lospalos or nearby cities?
Yes, likely. The epicenter was about 253 km east-northeast of Lospalos, so residents of eastern Timor-Leste probably felt light to moderate swaying, though the quake's 112 km depth softened the shaking considerably.

Is a tsunami possible from this earthquake?
No. This quake occurred 112 km underground, far too deep to displace the seafloor and generate a tsunami. No tsunami threat has been issued.

Should I expect aftershocks?
Aftershocks are possible after any magnitude 5.9 event, but deep earthquakes like this one typically produce fewer and weaker aftershocks than shallow quakes. If shaking happens again, drop, cover, and hold on.

Could this earthquake have caused damage?
Significant damage is unlikely at this depth and distance from populated areas. At most, communities nearest the epicenter might see minor effects like cracked plaster or fallen shelf items.

Reported Impact

8 people have reported feeling this quake to USGS’s “Did You Feel It?” system so far; the maximum reported shaking intensity is 2.5 on the Community Decimal Intensity scale; USGS’s automated PAGER system currently estimates a Green alert level (minimal expected casualties or damage).

Impact figures are from USGS as of when this alert was generated and can rise as more reports come in – this is not a final damage assessment.
