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 16 million people exposed to shaking

This earthquake may have been felt by around 16 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.

An estimated 1,652,000 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 12 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. In The Philippines , around 16 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 Laguilayan in Soccsksargen, The Philippines. Laguilayan is located 98 kilometer (61 mi) west-southwest of the epicenter. The intensity of shaking and damage in Laguilayan 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. Budta is located 128 km to the north-east and experienced an intensity of III (weak shaking, probably no damage). Malingao is located 127 km to the north-east and experienced an intensity of III (weak shaking, probably no damage). Davao is located 226 km to the east-northeast (intensity unknown, possibly low).

• Buayan, Southern Mindanao, Philippines: 1 person.

This is likely an aftershock

This earthquake was an aftershock. A larger mag. 5.4 earthquake struck 7 km (4 mi) north in advance of this 5.4 earthquake around 1 day earlier.

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, 59 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.
