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 65% likelyhood of between 0 and 1 fatalities, and a 96% chance that the number of fatalities falls no higher than 10.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 96% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 64 million people exposed to shaking

This earthquake may have been felt by around 64 million people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 15,470,000 people are expected to be exposed to this level. The majority of people (roughly 49 million) live in an area exposed to level III, where weak shaking and probably no damage is expected. All exposure to shaking was within the borders of Indonesia .

5 Aftershocks detected

After this earthquake struck, 5 smaller aftershocks occurred. At a distance of 30 km (18 mi) south of this earthquake, an aftershock struck 1 day later. It measured a magnitude of 3.1

Before this earthquake struck, 3 smaller foreshocks occurred. Roughly 2 days before this earthquake, a foreshock measuring MAG-2.8 was detected nearby this earthquake.

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 like this are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since March 22nd, 2024, when a 6.4 magnitude earthquake hit 247 km (154 mi) further north-northeast. An even stronger magnitude 7 earthquake struck on April 14th, 2023.

In total, 9 earthquakes with a magnitude of 5.7 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 year.

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.

It is very unlikely that this eartquake will cause any tsunami's. The reported magnitude is lower than the MAG-6.5 strength required to cause any earthquakes. In addition, this earthquake was not very shallow and appears to have occurred under land. 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 Not this earthquake.
This earthquake appears to have struck on land far from any coast.
Not this earthquake.
This earthquake had a magnitude of 5.7. Earthquakes of this strength are unlikely to trigger a tsunami.
Not this earthquake.
This earthquake occurred at a depth of 127 km (79 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami.
