Indonesia: Magnitude-5.3 offshore earthquake occurs south of Java Island April 22

A magnitude-5.3 earthquake occurred in the Indian Ocean south of Java Island at around 18:11 April 22. The epicenter was about 102 km (63 miles) south-southwest of Trenggalek, East Java Province. The tremor occurred at a depth of about 35 km (22 miles), and light shaking was probably felt throughout parts of central and western East Java Province, central and eastern Central Java Province, and the Special Region of Yogyakarta. There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
