Philippines: Magnitude-5.3 earthquake occurs in Philippine Sea, east of Luzon, at around 07:16 Sept. 4

A magnitude-5.3 earthquake occurred in the Philippine Sea to the east of Luzon at around 07:16 Sept. 4. The epicenter was about 31 km (20 miles) east-northeast of Casuguran, Philippines. The tremor occurred at a depth of about 28 km (17 miles), and light shaking was probably felt in northern parts of the Philippines. There have been no initial reports of damage or casualties as a result of the earthquake; significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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 where shaking occurred.
