Earthquake Summary

This earthquake hit under water in the Sulawesi Sea, 33 kilometers (20 mi) off the coast of The Philippines, 109 kilometer southwest of Malingao in Soccsksargen. The center of this earthquake had a very shallow depth of 10 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 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 17 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 17 million have been exposed to shaking at an MMI level of II or higher.

The highest earthquake impact level for this earthquake is V, which corresponds with moderate shaking and very light damage. Roughly 1,440 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 13 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. Roughly 17 million people were exposed to shaking in The Philippines , with level V (moderate shaking, very light damage) as the highest recorded. In Indonesia, shaking was experienced too.

Nearby towns and cities

This earthquake may have been felt in The Philippines . The closest significant population center near the earthquake is Maganoy in Rehiyong Autonomo sa Muslim na Mindanao, The Philippines. Maganoy is located 87 kilometer (54 mi) west-southwest of the epicenter. Maganoy experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Multiple major population centers exist within 300km of the earthquake that struck today. Budta is located 110 km to the north-east and experienced an intensity of IV (light shaking, likely no damage). Malingao is located 109 km to the north-east and experienced an intensity of IV (light shaking, likely no damage). Davao is located 216 km to the east-northeast (intensity unknown, possibly low).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

Shaking reported by 6 people

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 6 people have reported shaking in 4 places, all within Philippines.We keep updating this article as more ground reports become available. You may report that you felt this earthquake here.

Places with most reports:

• Buayan, Southern Mindanao, Philippines: 2 people.
• San Jose (General Santos City, South Cotabato), Southern Mindanao, Philippines: 2 people.
• Polomolok, Southern Mindanao, Philippines: 1 person.
• Conel, Southern Mindanao, Philippines: 1 person.

This is likely an aftershock

This earthquake is likely an aftershock of the MAG-5.9 earthquake that struck 2 hrs earlier. That main earthquake hit 11 km (7 mi) south-east of the epicenter of this MAG-5.4 aftershock.

Overview of foreshocks and aftershocks

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.

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, 63 earthquakes with a magnitude of 5.4 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.
