Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 fatalities.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 440 thousand people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 440 thousand have been exposed to shaking at an MMI level of II or higher.

An estimated 4,890 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. Intensity level III was experienced by the majority of people (around 410 thousand). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. In Indonesia , around 70 thousand people, with impact levels up to IV (light shaking, likely no damage). In Timor-Leste , around 370 thousand people.

Nearby towns and cities

This earthquake struck within proximity of multiple countries. Timor-Leste and Indonesia are both within 300km distance of its epicenter.

Located 139 kilometer (86 mi) north-east of the epicenter of this earthquake, Lospalos (Lautém, Timor-Leste) is the nearest significant population center. The intensity of shaking and damage in Lospalos is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

A complete list of nearby places is included below. Estimated intensity data (MMI) sourced from a shake-map published by the US Geographic Survey is shown where available (cities without data probably experienced little impact).

5 Aftershocks detected

After this earthquake struck, 5 smaller aftershocks occurred. Just 1 day after this main shock, an earthquake measuring MAG-4.9 was detected 89 km (55 mi) east of this earthquake.

This main shock was prefaced by 1 smaller foreshock. Nearby this earthquake a foreshock struck 2 days earlier. It measured a magnitude of 4.3

Overview of foreshocks and aftershocks

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.
Classification	Magnitude	When	Where
Foreshock	M 4.3	2 days earlier Mar 27, 2026 05:13 (Dili Time)	9 km (5 mi) W from Main Shock.
Main Shock This Earthquake	M 5.8	Mar 29, 2026 03:38 (Dili Time)	-
Aftershock	M 4.2	16 hrs later Mar 29, 2026 19:09 (Dili Time)	75 km (47 mi) NW from Main Shock.
Aftershock	M 2.7	22 hrs later Mar 30, 2026 01:30 (Dili Time)	39 km (24 mi) SW from Main Shock.
Aftershock	M 4.6	1 day later Mar 30, 2026 11:36 (Dili Time)	70 km (43 mi) E from Main Shock.
Aftershock	M 4.9	1 day later Mar 30, 2026 13:00 (Dili Time)	89 km (55 mi) E from Main Shock.
Aftershock	M 3.3	2 days later Mar 31, 2026 05:17 (Dili Time)	35 km (22 mi) SE from Main Shock.

More earthquakes coming?

Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since October 28th, 2025, when a 6.4 magnitude earthquake hit 260 km (161 mi) further east. An even stronger magnitude 7.6 earthquake struck on January 9th, 2023.

In total, 20 earthquakes with a magnitude of 5.8 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 6 months.

Tsunami very unlikely

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

For a serious tsunami to occur, earthquakes usually need to have a magnitude of at least 6.5 and occur at a shallow depth of maximum 100km. Neither are the case with this earthquake. However always stay cautious and monitor advice from local authorities.

Tsunami Risk Factors

Factor	Under Sea?	MAG-6.5 or stronger?	Shallow depth?
Explanation	Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami.	Under MAG 6.5: Very unlikely to cause a tsunami. MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes. MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.	Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake	This earthquake appears to have struck under the sea.	Not this earthquake. This earthquake had a magnitude of 5.8. Earthquakes of this strength are unlikely to trigger a tsunami.	Not this earthquake. This earthquake occurred at a depth of 159 km (99 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami.
