A powerful 7.8 magnitude offshore earthquake struck the southern Philippines on Monday, resulting in at least 35 fatalities and over 200 injuries. The tremor, the strongest recorded in the country this year, caused significant damage to buildings and triggered a deadly landslide.

The earthquake's epicentre was located offshore near Mindanao, the Philippines' second most populous island. It struck at a depth of approximately 33 kilometers (20 miles), about 32 kilometers (20 miles) southwest of Maasim town in Sarangani province. The seismic event has prompted international offers of support from allies including the United States, France, Japan, and New Zealand.

General Santos City was among the hardest-hit areas, with several low-rise buildings collapsing or sustaining severe damage. Tsunami damage was reported in at least one southern coastal village, with smaller waves observed in Indonesia, Palau, and as far as southern Japan. A landslide in Glan, Sarangani, claimed the lives of 13 villagers, according to provincial disaster-mitigation official Rene Punzalan.

President Ferdinand Marcos Jr. ordered the cancellation of classes and directed disaster-response agencies to provide immediate assistance to the affected provinces. "The national government is moving and we will not leave Mindanao behind," Marcos Jr. stated, emphasizing a commitment to support the region.

Most of the deaths were attributed to collapsing structures and falling debris, including in a damaged mosque in the southern provinces of South Cotabato and Davao Occidental, and on Balut Island, as reported by disaster-mitigation official Ednar Dayanghirang. Six stilt houses in a coastal village in Zamboanga del Sur province were also damaged by the quake and subsequent higher waves.

The Philippines is situated on the Pacific "Ring of Fire," a region known for its frequent seismic activity and volcanic eruptions, making earthquakes a common occurrence. The Philippine Institute of Volcanology and Seismology confirmed the magnitude and depth of the quake.

By mid-afternoon, the Pacific Tsunami Warning Center indicated that the threat of a widespread tsunami had largely passed, and Philippine officials lifted their tsunami warning. Rescue and relief efforts are ongoing in the affected areas as authorities assess the full extent of the damage.

Questions remain about the long-term impact on infrastructure and the ongoing recovery process for the affected communities. The immediate focus remains on search and rescue operations and providing aid to those displaced or injured by the powerful seismic event.
