The death toll from a strong 7.8 magnitude earthquake off the island of Mindanao in the southern Philippines this Monday (8) has risen to at least 32. Dozens of people have been injured, disaster area authorities said, as Manila intensifies search and rescue operations. The earthquake, which triggered tsunami warnings in several countries, hit Sarangani province early in the morning, about 20 km from the coast. The tremors were felt strongly in Mindanao and 420 km away in the city of Manado on the Indonesian island of Sulawesi. Related news: Magnitude 6.9 earthquake hits northern Chile. Earthquake in Chile is felt in neighborhoods of the city of São Paulo. The Philippines has mobilized military and disaster response teams, and authorities are verifying preliminary reports of 32 people killed and 134 injured in Mindanao, most due to falling debris and landslides, according to Civil Defense representatives. Tsunami warnings were canceled after more than six hours in the southern Philippines, northern Indonesia and the Malaysian state of Sabah on the island of Borneo, where residents in coastal areas were told to evacuate immediately to higher ground. The disaster occurred eight months after the Philippines suffered its deadliest tremor in 12 years, when a 6.9 magnitude shallow earthquake struck the central island of Cebu, killing 79 people. Two strong earthquakes struck Mindanao two weeks later, the strongest being magnitude 7.4. President Ferdinand Marcos Jr. ordered an immediate response to the disaster in Mindanao, an island the size of South Korea. Agencies were told to prepare relief supplies and evacuation centers and be ready for possible rescue operations. "The national government is moving and we will not leave Mindanao behind," Marcos said in a statement. The Philippines and Indonesia experience hundreds of earthquakes every year and are situated in tectonically complex parts of the "Pacific Ring of Fire," a seismically active belt that stretches from South America to the Russian Far East. *Reproduction of this content is prohibited.
