Earthquake Summary
This earthquake hit under water in the Sulawesi Sea, 106 kilometers (66 mi) off the coast of The Philippines, 188 kilometer southwest of Malingao in Soccsksargen. The center of this earthquake had a very deep depth of 628 km. Deep earthquakes usually have less impact than shallower earthquakes of similar strenght.

Potential tsunami risk
There is a potential tsunami risk in the aftermath of this earthquake, immediately evacuate to higher grounds away from coastal areas and monitor advice from local authorities. The US Geographic Survey organization has indicated a potential risk for tsunami's following this earthquake.
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. | This earthquake had a magnitude of 7.1. Earthquakes of this strength could trigger a tsunami. | Not this earthquake. This earthquake occurred at a depth of 628 km (390 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami. |
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 9 million people exposed to shaking
The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 9 million have been exposed to shaking at an MMI level of II or higher.
An estimated 2,151,000 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. Intensity level III was experienced by the majority of people (around 6.6 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of The Philippines .

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.
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 not so common in the region, but it's not the first time. This is the strongest earthquake to hit since January 10th, 2017, when a 7.3 magnitude earthquake hit 189 km (117 mi) further south-southwest. That was also the heaviest earthquake to hit the region in the past 10 years.
In total, 1 earthquake with a magnitude of 7.1 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 10 years.
