Deep M6.5 earthquake strikes northwest Java, Indonesia on September 11, 2026 (Updated)

A deep M6.5 earthquake was recorded at 21:23 UTC on September 11, 2026, approximately 126 km (78 miles) north-northeast of Teluknaga, Indonesia. The event occurred at a substantial depth of 372.0 km (231.1 miles), according to USGS data.

The coordinates place the hypocenter in the region northwest of Java, near major population centers but deep beneath the Earth’s surface. This depth reduces the potential for significant surface shaking, although the broader area, including Jakarta and coastal Java, is seismically active and densely populated.

The affected region is host to critical infrastructure such as international ports, airports, and key industrial facilities common to the Java region, given its proximity to major urban and economic areas.

There is no tsunami threat associated with this earthquake, based on its location and available data.

USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity was III, with 21 felt reports provided. The significance index is 657 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

Indonesia lies along the Pacific Ring of Fire, where the Indo-Australian Plate subducts beneath the Eurasian Plate, making it highly prone to deep and shallow earthquakes.
