Earthquake Summary

This earthquake hit under water in the Sulawesi Sea, 71 kilometers (44 mi) off the coast of The Philippines, 134 kilometer south of General Santos in Soccsksargen. The center of this earthquake had a quite shallow depth of 35 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

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 4.3 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 4.3 million have been exposed to shaking at an MMI level of II or higher.

An estimated 37,990 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 4 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. Roughly 4.1 million people were exposed to shaking in The Philippines , with level IV (light shaking, likely no damage) as the highest recorded. Roughly 250 thousand people were exposed to shaking in Indonesia .

Nearby towns and cities

This earthquake may have been felt in The Philippines . The closest significant population center near the earthquake is Glan in Soccsksargen, The Philippines. Glan is located 101 kilometer (63 mi) south of the epicenter. The intensity of shaking and damage in Glan is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

Major cities near this earthquake: General Santos is located 134 km to the north and experienced an intensity of III (weak shaking, probably no damage). Davao is located 242 km to the north (intensity unknown, possibly low). Budta is located 272 km to the north (intensity unknown, possibly low).

The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

This is likely an aftershock

Approximately 10 hrs before this earthquake hit, a larger 7.8 magnitude earthquake struck 80 km (50 mi) north of this one. For that reason, we classify the Mag. 5.6 earthquake as an aftershock.

Overview of foreshocks and aftershocks

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.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 65 earthquakes with a magnitude of 5.6 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.

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.
