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

Light shaking and likely no damage may have been experienced by an estimated 55,100 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 3.8 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. Roughly 3.7 million people were exposed to shaking in The Philippines , with level IV (light shaking, likely no damage) as the highest recorded. In Indonesia , around 250 thousand people.

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 110 kilometer (68 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).

Multiple large cities are in proximity of today's earthquake. Davao is located 246 km to the north (intensity unknown, possibly low). General Santos is located 142 km to the north and experienced an intensity of III (weak shaking, probably no damage). Budta is located 283 km to the northwest (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.

This is likely an aftershock

This earthquake was an aftershock. A larger mag. 5.6 earthquake struck 17 km (10 mi) west in advance of this 5.4 earthquake around 3 days earlier.

Overview of foreshocks and aftershocks

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.

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, 124 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 29 days.

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.
