Earthquake Summary

The earthquake struck on land in Indonesia, 32 kilometer (20 mi) north-northeast of Kupang in East Nusa Tenggara. The center of this earthquake had a quite shallow depth of 30 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

2 Aftershocks detected

Since this main shock, 2 smaller aftershocks were detected. Just 16 hrs after this main shock, an earthquake measuring MAG-3.4 was detected 20 km (12 mi) south of this earthquake.

This main shock was prefaced by 6 smaller foreshocks. A 4.6 magnitude earthquake hit 6 hrs earlier nearby.

More earthquakes coming?

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

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 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 November 1st, 2023, when a 6.1 magnitude earthquake hit 16 km (10 mi) further south-southeast. An even stronger magnitude 6.5 earthquake struck on November 4th, 2015.

In total, 24 earthquakes with a magnitude of 5.2 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 5 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.

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. 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 on land near a coastal area (6 km from the sea). Not this earthquake.
This earthquake had a magnitude of 5.2. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 30 km (19 mi). Earthquakes this shallow could trigger a tsunami.
