Shallow M5.5 earthquake hits offshore Java, Indonesia

A shallow earthquake registered M5.5 was recorded at 09:27 UTC on September 14, 2026, approximately 187 km (116 miles) south-southwest of Pelabuhanratu, offshore Java, Indonesia. The hypocenter was located at a depth of 10.0 km (6.2 miles), according to data supplied by the USGS.

Based on its coordinates (105.9°E, 8.5°S), the event took place in the Indian Ocean, off the southern coast of western Java. This region is characterized by significant offshore seismicity, with several population centers along the coast, including Pelabuhanratu and Sukabumi.

Nearby critical infrastructure may include maritime shipping lanes, fishing ports, and coastal transportation networks serving Java’s southern coastline. Major energy facilities and air transport are generally further inland but could serve the broader region.

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

The significance index is 465 (on a scale that runs through 1 000), based on magnitude, available felt reports, and estimated impact.

Indonesia sits atop the seismically active Ring of Fire, where the Indo-Australian Plate is subducting beneath the Eurasian Plate, making the region prone to frequent earthquake activity, especially offshore southern Java.
