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 0.8 million people exposed to shaking

An estimated 0.8 million 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.

The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 26,840 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 0.8 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Japan .

15,100	II	Very weak	None
797,800	III	Weak	Probably none
26,840	IV	Light	Likely none
0	V	Moderate	Very light
0	VI	Strong	Light

Nearby towns and cities

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

Multiple large cities are in proximity of today's earthquake. Kagoshima is located 199 km to the north and experienced an intensity of III (weak shaking, probably no damage). Miyazaki is located 241 km to the north-northeast (intensity unknown, possibly low). Miyakonojō is located 216 km to the north (intensity unknown, possibly low).

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).

Risk of aftershocks?

We monitor for foreshocks or aftershocks that have a magnitude of 2.5+ and occur within 100km (62 mi) of the epicenter of this earthquake. So far no such earthquakes have been detected.

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

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 are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since August 8th, 2024, when a 7.1 magnitude earthquake hit 227 km (141 mi) further north-northeast. That was also the heaviest earthquake to hit the region in the past 10 years.

In total, 11 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.

Low tsunami risk

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.

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.

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 5.7. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 29 km (18 mi). Earthquakes this shallow could trigger a tsunami.
