2 Aftershocks detected
After this earthquake struck, 2 smaller aftershocks occurred. Just 2 days after this main shock, an earthquake measuring MAG-4.3 was detected 80 km (50 mi) north of this earthquake.
Overview of foreshocks and aftershocks
| Classification | Magnitude | When | Where |
|---|---|---|---|
| Main Shock This Earthquake |
M 5.1 |
Aug 23, 2024 03:42 (Dili Time) | - |
| Aftershock | M 3.7 |
60 mins later Aug 23, 2024 04:42 (Dili Time) | 10 km (6 mi) NNE from Main Shock. |
| Aftershock | M 4.3 |
2 days later Aug 24, 2024 19:37 (Dili Time) | 80 km (50 mi) N 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.
In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since November 6th, 2023, when a 5.2 magnitude earthquake hit 210 km (131 mi) further east. An even stronger magnitude 7.3 earthquake struck on December 29th, 2021.
In total, 49 earthquakes with a magnitude of 5.1 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 2 months.
Low tsunami risk
Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so 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 5.1. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 10 km (6 mi). Earthquakes this shallow could trigger a tsunami. |
