Aftershocks detected
After this earthquake struck, 1 smaller aftershock occurred. Just 4 hrs after this main shock, an earthquake measuring MAG-4.6 was detected 68 km (42 mi) north-east of this earthquake.
Overview of foreshocks and aftershocks
Classification | Magnitude | When | Where |
---|---|---|---|
Main Shock This Earthquake |
M 5.1 |
Apr 8, 2024 10:25 (Tokyo Time) | - |
Aftershock | M 4.6 |
4 hrs later Apr 8, 2024 13:57 (Tokyo Time) | 68 km (42 mi) NE 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.
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 of this strength are very common in the region. This is the strongest earthquake to hit since November 10th, 2023, when a 5.3 magnitude earthquake hit 72 km (45 mi) further southwest. An even stronger magnitude 7 earthquake struck on April 15th, 2016.
In total, 49 earthquakes with a magnitude of 5.1 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
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 | This earthquake appears to have struck on land near a coastal area (6 km from the sea). | Not this earthquake. This earthquake had a magnitude of 5.1. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 53 km (33 mi). Earthquakes this shallow could trigger a tsunami. |
