Tectonic Summary

The June 7, 2024, M 7.8 earthquake south of the island of Mindanao, Philippines, resulted from thrust faulting. The earthquake’s depth and moment‑tensor estimate indicate the event occurred within the complex zone of active deformation associated with westward subduction of the Philippine plate beneath the Sunda plate. Northeastern Indonesia and southern Philippines are characterized by complex tectonics in which motions of numerous small plates accommodate the large-scale convergence between the Philippine Sea and Sunda plates. At the location of this earthquake, the Philippines plate is moving towards the Sunda at 7.3 cm/yr.

While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip distributed over a broad fault area. Thrust faulting events of the size of the June 7 earthquake are typically about 120 x 50 km in size (length x width).

The region around this earthquake is tectonically active and large earthquakes are common. Since 1900, 35 earthquakes with a magnitude of M 7+ have occurred within 300 km of this event. The largest was a magnitude 8.3 earthquake on August 15th, 1918 that occurred 118 km to the west. More recently, a magnitude 7.4 event occurred on October 10, 2025, 260 km to the northeast, resulting in more than ten fatalities.
