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 56 million people exposed to shaking

An estimated 56 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.

An estimated 10,180,000 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. The majority of people (roughly 46 million) live in an area exposed to level III, where weak shaking and probably no damage is expected. All exposure to shaking was within the borders of Indonesia .

Nearby towns and cities

This earthquake may have been felt in Indonesia . Trenggalek in East Java, Indonesia is the nearest significant place from the epicenter. The earthquake occurred 95 kilometer (59 mi) south-southwest of Trenggalek. The intensity of shaking and damage in Trenggalek 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. Surabaya is located 240 km to the north-east and experienced an intensity of III (weak shaking, probably no damage). Semarang is located 218 km to the north-northwest and experienced an intensity of III (weak shaking, probably no damage). Yogyakarta is located 145 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.

3 Aftershocks detected

Since this main shock, 3 smaller aftershocks were detected. At a distance of 11 km (7 mi) south-southwest of this earthquake, an aftershock struck 4 mins later. It measured a magnitude of 4

In the days before this main shock, 11 smaller foreshocks were detected. Nearby this earthquake a foreshock struck 2 days earlier. It measured a magnitude of 3.2

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.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

This is the strongest earthquake in 3 years

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since June 30th, 2023, when a 5.9 magnitude earthquake hit 133 km (83 mi) further west. An even stronger magnitude 6 earthquake struck on April 10th, 2021.

In total, 3 earthquakes with a magnitude of 5.8 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

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.
