General Santos International Airport in the Philippines has temporarily suspended operations due to a significant earthquake measuring 7.8 on the Richter scale that struck off Maasim, Sarangani on Monday morning. The earthquake, which occurred at 7:37 a.m., was initially reported as a 7.0 magnitude but was later upgraded by the Philippine Institute of Volcanology and Seismology (Phivolcs).

CAAP is currently assessing air navigation facilities and operational capabilities to ensure safety. Passengers are encouraged to check with their airlines for flight updates. In response to the earthquake, President Ferdinand Marcos Jr. has ordered immediate action from relevant government agencies, and classes in affected areas across Mindanao have been suspended until further notice.
