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.

An estimated 270 people were exposed to level V. At this level, moderate shaking and very light damage can be expected. Intensity level III was experienced by the majority of people (around 14 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 17 million people, with impact levels up to V (moderate shaking, very light damage).

Nearby towns and cities

This earthquake may have been felt in The Philippines . Maganoy in Rehiyong Autonomo sa Muslim na Mindanao, The Philippines is the nearest significant place from the epicenter. The earthquake occurred 88 kilometer (55 mi) west-southwest of Maganoy. Maganoy experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Major cities near this earthquake: Budta is located 108 km to the north-east and experienced an intensity of IV (light shaking, likely no damage). Malingao is located 108 km to the north-east and experienced an intensity of IV (light shaking, likely no damage). Davao is located 219 km to the east-northeast (intensity unknown, possibly low).

A complete list of nearby places is included below. Estimated intensity data (MMI) sourced from a shake-map published by the US Geographic Survey is shown where available (cities without data probably experienced little impact).

This is likely an aftershock

This earthquake was an aftershock. A larger mag. 5.9 earthquake struck 19 km (12 mi) south-southeast in advance of this 5.6 earthquake around 2 hrs earlier.

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.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 32 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 4 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.
