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 3.9 million people exposed to shaking

This earthquake may have been felt by around 3.9 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 626,800 people are expected to be exposed to this level. The majority of people (roughly 3.3 million) live in an area exposed to level III, where weak shaking and probably no damage is expected.

People in 2 countries have been exposed to shaking. Roughly 3.6 million people were exposed to shaking in The Philippines , with level IV (light shaking, likely no damage) as the highest recorded. In Indonesia , around 250 thousand people.

Nearby towns and cities

This earthquake may have been felt in The Philippines . The closest significant population center near the earthquake is Glan in Soccsksargen, The Philippines. Glan is located 144 kilometer (89 mi) south-east of the epicenter. The intensity of shaking and damage in Glan is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Major cities near this earthquake: Davao is located 249 km to the north (intensity unknown, possibly low). Budta is located 316 km to the northwest (intensity unknown, possibly low). General Santos is located 171 km to the northwest and experienced an intensity of IV (light shaking, likely 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).

Shaking reported by 11 people in 2 countries

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 11 people have reported shaking in 5 places in 2 countries (Philippines, Indonesia).We keep updating this article as more ground reports become available. You may report that you felt this earthquake here.

5 Aftershocks detected

This main shock was followed by 5 smaller aftershocks. At a distance of 51 km (32 mi) southwest of this earthquake, an aftershock struck 2 days later. It measured a magnitude of 3.5

In the days before this main shock, 2 smaller foreshocks were detected. Roughly 2 days before this earthquake, a foreshock measuring MAG-3.8 was detected nearby this earthquake.

Overview of foreshocks and aftershocks

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.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

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 January 10th, 2026, when a 6.4 magnitude earthquake hit 158 km (98 mi) further south-east. An even stronger magnitude 7.4 earthquake struck on October 10th, 2025.

In total, 38 earthquakes with a magnitude of 6 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 3 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.
