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 230 thousand people exposed to shaking
An estimated 230 thousand have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.
An estimated 159,600 people were exposed to level IV. At this level, light shaking and likely no damage can be expected.
People in 2 countries have been exposed to shaking. In Guam , around 170 thousand people, with impact levels up to IV (light shaking, likely no damage). In Northern Mariana Islands , around 50 thousand people.

Nearby towns and cities
Guam and Northern Mariana Islands are both located within 300km distance of the epicenter of the earthquake.
The closest significant population center near the earthquake is Yigo Village in Yigo, Guam. Yigo Village is located 24 kilometer (15 mi) north of the epicenter. The intensity of shaking and damage in Yigo Village is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).
The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

Earthquake Intensity Map
The intensity in shaking and damage by this earthquake is illustrated through the map below. The highest intensity measured for this earthquake is IV.
Aftershocks detected
Since this main shock, 1 smaller aftershock was detected. A 4.2 magnitude earthquake hit 1 day later 22 km (14 mi) east of this earthquake.
Before this earthquake struck, 1 smaller foreshock occurred. A 4.1 magnitude earthquake hit 3 days earlier nearby.
Overview of foreshocks and aftershocks
| Classification | Magnitude | When | Where |
|---|---|---|---|
| Foreshock | M 4.1 |
3 days earlier Nov 7, 2025 16:08 (Guam Time) | 33 km (21 mi) ENE from Main Shock. |
| Main Shock This Earthquake |
M 5.4 |
Nov 10, 2025 08:53 (Guam Time) | - |
| Aftershock | M 4.2 |
1 day later Nov 11, 2025 11:33 (Guam Time) | 22 km (14 mi) E from Main Shock. |
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.
It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since November 4th, 2025, when a 5.9 magnitude earthquake hit 243 km (151 mi) further southwest. An even stronger magnitude 6.1 earthquake struck on August 14th, 2023.
In total, 41 earthquakes with a magnitude of 5.4 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.
Tsunami very unlikely
For a serious tsunami to occur, earthquakes usually need to have a magnitude of at least 6.5 and occur at a shallow depth of maximum 100km. Neither are the case with this earthquake. 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 under the sea. | Not this earthquake. This earthquake had a magnitude of 5.4. Earthquakes of this strength are unlikely to trigger a tsunami. |
Not this earthquake. This earthquake occurred at a depth of 109 km (67 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami. |
