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 2 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 2 million have been exposed to shaking at an MMI level of II or higher.

Strong shaking and probably light damage may have been experienced by an estimated 230 people. At VI, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 1.6 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. In Indonesia , around 1.8 million people, with impact levels up to VI (strong shaking, probably light damage). In Papua New Guinea , around 250 thousand people.

People	MMI Level	Shaking	Damage
0	I	Not noticable	None
327,500	II	Very weak	None
1,574,000	III	Weak	Probably none
143,100	IV	Light	Likely none
960	V	Moderate	Very light
230	VI	Strong	Light
0	VII	Very Strong	Moderate
0	VIII	Severe	Moderate to heavy
0	IX	Violent	Heavy
0	X	Extreme	Very heavy

Nearby towns and cities

This earthquake may have been felt in Indonesia . Located 105 kilometer (65 mi) south of the epicenter of this earthquake, Abepura (Papua, Indonesia) is the nearest significant population center. The intensity of shaking and damage in Abepura is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

9 Aftershocks detected

After this earthquake struck, 9 smaller aftershocks occurred. At a distance of 85 km (53 mi) northwest of this earthquake, an aftershock struck 23 hrs later. It measured a magnitude of 4.1

This main shock was prefaced by 3 smaller foreshocks. A 4.2 magnitude earthquake hit 3 days earlier nearby.

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.

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

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 March 26th, 2026, when a 5.7 magnitude earthquake hit 115 km (71 mi) further west. An even stronger magnitude 6.4 earthquake struck on October 16th, 2025.

In total, 59 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 2 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	Not this earthquake. This earthquake appears to have struck on land far from any coast.	Not this earthquake. This earthquake had a magnitude of 5.2. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 47 km (29 mi). Earthquakes this shallow could trigger a tsunami.
