Philippines: Tsunami warning lifted following magnitude-7.1 earthquake in the Philippine Sea southeast of Mindanao early Aug. 12 /update 2

Event

Officials have lifted a tsunami warning issued following a strong earthquake that occurred southeast of Mindanao early Aug. 12. Tsunami waves constituting only minor fluctuations in sea levels were reportedly observed.

The magnitude-7.1 earthquake occurred in the Philippine Sea southeast of Mindanao at around 01:46 Aug. 12. The epicenter was about 142 km (88 miles) east-southeast of Davao City, the Philippines. The tremor occurred at a depth of about 65 km (40 miles), and strong-to-violent shaking was reported in areas near the epicenter, with moderate shaking occurring in areas of Mindanao further from the epicenter. There have been no initial reports of damage or casualties, though at least some degree of structural damage is highly likely in parts of Davao Oriental Province. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are likely over the coming days.

Officials may shut down transportation infrastructure in the tremor zone to check for damage. The earthquake may have triggered landslides in some areas. Utility outages are also possible, particularly near the earthquake's epicenter.

Advice

Vacate multistoried buildings or unreinforced structures in areas where strong shaking occurred; aftershocks could cause additional damage. Cellular networks may be overwhelmed; use text messaging if services are available. Due to the threat of landslides, seek updated information on road conditions before driving in hilly areas in the affected area. Confirm all transport reservations in the affected area.
