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 11 million people exposed to shaking

This earthquake may have been felt by around 11 million people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 3,236,000 people are expected to be exposed to this level. The majority of people (roughly 7.4 million) live in an area exposed to level III, where weak shaking and probably no damage is expected.

People in 2 countries have been exposed to shaking. In The Philippines , around 11 million people, with impact levels up to IV (light shaking, likely no damage). People were exposed to shaking in Indonesia as well.

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 33 kilometer (21 mi) south of the epicenter. The intensity of shaking and damage in Glan is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Multiple large cities are in proximity of today's earthquake. General Santos is located 65 km to the north and experienced an intensity of IV (light shaking, likely no damage). Davao is located 176 km to the north and experienced an intensity of III (weak shaking, probably no damage). Budta is located 206 km to the northwest and experienced an intensity of III (weak shaking, probably no damage).

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.

This is likely an aftershock

This earthquake is likely an aftershock of the MAG-7.8 earthquake that struck 12 hrs earlier. That main earthquake hit 24 km (15 mi) west of the epicenter of this MAG-5.5 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, 101 earthquakes with a magnitude of 5.5 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 month.

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.
