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 64 million people exposed to shaking

This earthquake may have been felt by around 64 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.

The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 13,250,000 people are expected to be exposed to this level. The majority of people (roughly 51 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 . Ponorogo in East Java, Indonesia is the nearest significant place from the epicenter. The earthquake occurred 20 kilometer (12 mi) south-southwest of Ponorogo. The intensity of shaking and damage in Ponorogo is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Major cities near this earthquake: Surabaya is located 174 km to the east-northeast and experienced an intensity of III (weak shaking, probably no damage). Semarang is located 156 km to the northwest and experienced an intensity of III (weak shaking, probably no damage). Surakarta is located 79 km to the northwest and experienced an intensity of IV (light shaking, likely 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.

4 Aftershocks detected

After this earthquake struck, 4 smaller aftershocks occurred. At a distance of 55 km (34 mi) south-southwest of this earthquake, an aftershock struck 4 hrs later. It measured a magnitude of 3

Before this earthquake struck, 3 smaller foreshocks occurred. Roughly 2 days before this earthquake, a foreshock measuring MAG-2.8 was detected nearby this earthquake.

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.

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 March 22nd, 2024, when a 6.4 magnitude earthquake hit 263 km (163 mi) further north-northeast. An even stronger magnitude 7 earthquake struck on April 14th, 2023.

In total, 9 earthquakes with a magnitude of 5.7 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 year.

Tsunami very unlikely

It is very unlikely that this eartquake will cause any tsunami's. The reported magnitude is lower than the MAG-6.5 strength required to cause any earthquakes. In addition, this earthquake was not very shallow and appears to have occurred under land. However always stay cautious and monitor advice from local authorities.
