A minor magnitude 3.5 earthquake struck near SOUTH OF JAVA, INDONESIA on Friday, September 11, 2026 at 12:51:10 PM UTC. This shallow crustal event (13.0 km depth) released energy equivalent to approximately 3 tons of TNT. Here is the verified BMKG telemetry, live epicenter map, and ground shaking assessment.

A magnitude 3.5 event is classified as a minor earthquake. Often felt by people indoors, especially on upper floors. Hanging objects may swing slightly; structural damage is extremely rare.
Felt by almost no one except under extraordinarily favorable conditions.

Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:
Because seismic scales are logarithmic, each whole integer increase represents:
This archipelago is situated along the Sunda and Philippine megathrust subduction zones within the Pacific Ring of Fire. The Indo-Australian Plate converges northeastward beneath the Eurasian and Sunda plates, producing massive tectonic friction, deep oceanic trenches, and widespread volcanic arcs.
Originating at a depth of 13.0 km (Earth's Crust (0–70 km)), this rupture occurred occurred within the brittle upper crust. shallow earthquakes produce the highest peak ground acceleration and the sharpest surface shaking.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 3.5. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Indonesia are advised to check living spaces for unsecured items.
