Minimal impact predicted

The US Geographic Survey (USGS) describes the impact of this earthquake as follows:

One person died of a heart attack at Bandung. Three persons injured and 24 houses damaged in Bandung; 10 homes damaged in Bogor; 2 people injured, 2 structures collapsed and 117 others damaged in Ciamis; 3 homes and 1 building damaged in Cianjur; 3 buildings damaged in Cimahi; 6 persons injured, 16 buildings destroyed and 496 damaged in Garut; 1 home destroyed and 17 damaged in Sukabumi; 1 person injured, 13 homes destroyed, 28 homes and 8 buildings damaged at Tasikmalaya.

Based on scientific estimates by the 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 69 million people exposed to shaking

An estimated 69 million have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.

Moderate shaking and very light damage may have been experienced by an estimated 3,213,000 people. At V, it is the highest MMI level this earthquake has caused. The majority of people (roughly 66 million) live in an area exposed to level IV, where light shaking and likely no damage is expected. All exposure to shaking was within the borders of Indonesia .

3 Aftershocks detected

After this earthquake struck, 3 smaller aftershocks occurred. At a distance of 68 km (42 mi) east-southeast of this earthquake, an aftershock struck 1 day later. It measured a magnitude of 3.7

In the days before this main shock, 3 smaller foreshocks were detected. A 4.2 magnitude earthquake hit 3 days earlier nearby.

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 are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since January 14th, 2022, when a 6.6 magnitude earthquake hit 255 km (159 mi) further west-northwest. An even stronger magnitude 6.9 earthquake struck on August 2nd, 2019.

In total, 3 earthquakes with a magnitude of 6.1 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 3 years.

Low tsunami risk

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

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.

Tsunami Risk Factors

Factor Under Sea? MAG-6.5 or stronger? Shallow depth?
Explanation Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake This earthquake appears to have struck under the sea. Not this earthquake.
This earthquake had a magnitude of 6.1. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 63 km (39 mi). Earthquakes this shallow could trigger a tsunami.
