On June 8, 2026, a powerful magnitude 7.8 earthquake struck Mindanao, causing significant geological changes in Sultan Naga Dimaporo, Lanao del Norte. The earthquake led to the sea waters receding by approximately two meters from the shore, prompting local officials to cancel classes in the town's 16 coastal villages as a precaution. Jennifer Senerpida, the Municipal Disaster Risk Reduction Management Officer, reported that the waters returned to normal within 15 minutes after receding. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) issued a tsunami alert for several provinces, although Lanao del Norte was not included. In response to the earthquake, Iligan City Mayor Frederick W. Siao ordered a suspension of classes from June 8 to 9 to evaluate the structural integrity of school buildings. The earthquake's epicenter was identified about 32 kilometers southwest of Maasim, Sarangani.
