Aftershocks detected
This main shock was followed by 1 smaller aftershock. At a distance of 25 km (15 mi) west of this earthquake, an aftershock struck 17 hrs later. It measured a magnitude of 4
Overview of foreshocks and aftershocks
Classification | Magnitude | When | Where |
---|---|---|---|
Main Shock This Earthquake |
M 5.1 |
Sep 7, 2024 13:16 (Taipei Time) | - |
Aftershock | M 4.0 |
17 hrs later Sep 8, 2024 05:53 (Taipei Time) | 25 km (15 mi) W 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.
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 August 15th, 2024, when a 6.1 magnitude earthquake hit 19 km (12 mi) further south-southeast. An even stronger magnitude 7.4 earthquake struck on April 2nd, 2024.
In total, 142 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 26 days.
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.
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 5.1. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 22 km (14 mi). Earthquakes this shallow could trigger a tsunami. |
