Minimal impact predicted

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

Six people injured, one building destroyed in Probolinggo; at least 279 homes and 36 buildings damaged in Sumenep; several buildings damaged in the Jember-Pamekasan-Situbondo area; .

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 100% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 32 million people exposed to shaking

An estimated 32 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.

Strong shaking and probably light damage may have been experienced by an estimated 218,700 people. At VI, it is the highest MMI level this earthquake has caused. Intensity level IV was experienced by the majority of people (around 26 million). In their region, light shaking and likely no damage can be expected. All exposure to shaking was within the borders of Indonesia .

Nearby towns and cities

This earthquake may have been felt in Indonesia . The closest significant population center near the earthquake is Kalianget in East Java, Indonesia. Kalianget is located 32 kilometer (20 mi) east-southeast of the epicenter. The intensity of shaking and damage in Kalianget is estimated to be around level VI on the Modified Mercalli Intensity scale (strong shaking, probably light damage).

Multiple major population centers exist within 300km of the earthquake that struck today. Surabaya is located 158 km to the west and experienced an intensity of IV (light shaking, likely no damage). Situbondo is located 59 km to the south-southwest and experienced an intensity of V (moderate shaking, very light damage). Denpasar is located 197 km to the south-east and experienced an intensity of IV (light shaking, likely no damage).

The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

56 Aftershocks detected

After this earthquake struck, 56 smaller aftershocks occurred. A 4.4 magnitude earthquake hit 26 mins later 9 km (6 mi) southwest of this earthquake.

This main shock was prefaced by 2 smaller foreshocks. Roughly 2 hrs before this earthquake, a foreshock measuring MAG-2.8 was detected nearby this earthquake.

Overview of foreshocks and aftershocks

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

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

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 250 km (155 mi) further northwest. An even stronger magnitude 7.1 earthquake struck on August 28th, 2023.

In total, 11 earthquakes with a magnitude of 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 year.

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.
