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 60 million people exposed to shaking

This earthquake may have been felt by around 60 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.

An estimated 921,700 people were exposed to level V. At this level, moderate shaking and very light damage can be expected. Intensity level IV was experienced by the majority of people (around 42 million). In their region, light shaking and likely no damage can be expected. All exposure to shaking was within the borders of Japan .

Nearby towns and cities

This earthquake may have been felt in Japan . Located 2 kilometer (1 mi) south of the epicenter of this earthquake, Ōtsuki (Yamanashi, Japan) is the nearest significant population center. The intensity of shaking and damage in Ōtsuki is estimated to be around level V on the Modified Mercalli Intensity scale (moderate shaking, very light damage).

Multiple large cities are in proximity of today's earthquake. Tokyo is located 65 km to the east and experienced an intensity of IV (light shaking, likely no damage). Yokohama is located 64 km to the east and experienced an intensity of IV (light shaking, likely no damage). Kawasaki is located 68 km to the east and experienced an intensity of IV (light shaking, likely no damage).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

2 Aftershocks detected

After this earthquake struck, 2 smaller aftershocks occurred. Just 6 hrs after this main shock, an earthquake measuring MAG-4.2 was detected 98 km (61 mi) east of this earthquake.

This main shock was prefaced by 1 smaller foreshock. Nearby this earthquake a foreshock struck 11 hrs earlier. It measured a magnitude of 4.5

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.
Classification	Magnitude	When	Where
Foreshock	M 4.5	11 hrs earlier Jun 26, 2026 11:48 (Tokyo Time)	94 km (59 mi) NE from Main Shock.
Main Shock This Earthquake	M 5.2	Jun 26, 2026 22:29 (Tokyo Time)	-
Aftershock	M 3.3	48 mins later Jun 26, 2026 23:17 (Tokyo Time)	12 km (7 mi) S from Main Shock.
Aftershock	M 4.2	6 hrs later Jun 27, 2026 03:59 (Tokyo Time)	98 km (61 mi) E from 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.

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 June 26th, 2026, when a 5.8 magnitude earthquake hit 139 km (86 mi) further east. An even stronger magnitude 7.5 earthquake struck on January 1st, 2024.

In total, 66 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 43 km (27 mi). Earthquakes this shallow could trigger a tsunami.
