Roughly 5.5 million people exposed to shaking
An estimated 5.5 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 728,000 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 4.8 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of The Philippines .

2 Aftershocks detected
Since this main shock, 2 smaller aftershocks were detected. Just 19 hrs after this main shock, an earthquake measuring MAG-3.7 was detected 99 km (61 mi) west-northwest of this earthquake.

Aftershock | M 3.7 |
19 hrs later Oct 2, 2024 11:51PM (Manila Time) | 99 km (61 mi) WNW from Main Shock. |
More earthquakes coming?
Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.
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 of this strength occur quite regularly in the region. This is the strongest earthquake to hit since April 4th, 2023, when a 6.2 magnitude earthquake hit 91 km (57 mi) further south-east. An even stronger magnitude 6.6 earthquake struck on August 18th, 2020.
In total, 5 earthquakes with a magnitude of 5.9 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 years.
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 5.9. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 10 km (6 mi). Earthquakes this shallow could trigger a tsunami. |
