A potential tsunami threatens the Philippines and Malaysia after a 7.8-magnitude earthquake in the Celebes Sea on Monday morning Philippine Time, according to the U.S. Tsunami Warning System. A tsunami advisory has also been issued for Guam.

The advisory was issued for coastal areas in Ibaraki, Chiba, Tokyo, Kanagawa, Shizuoka, Aichi, Mie, Wakayama, Kochi, Miyazaki, Kagoshima and Okinawa prefectures.

An 8.2 magnitude earthquake struck near Mindanao in the Philippines, triggering tsunami warnings across the western Pacific region, including Indonesia and Taiwan.

A recent international scientific study has pinpointed Balerma in El Ejido as the Spanish site likely to bear the brunt of tsunami energy from a rupture along the Averroes fault in the Alboran Sea.
