Near the Cotabato Trench, two of the largest 20th century Philippine earthquakes: the 1918 Celebes Sea earthquake (8.3 Mw) and the 1976 Moro Gulf earthquake (8.0 Mw). Also included is the recent 2002 Mindanao earthquake (7.5 Mw). The Moro Gulf, part of the Celebes Sea, is labeled for context.The 1918 Celebes Sea earthquake occurred on August 15 at 12:18 UTC near the Moro Gulf coast of Mindanao.[2] It had a magnitude of 8.3 on the moment magnitude scale[3] and a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale.
This event in the southern Philippines triggered a large tsunami, with a maximum run-up of 7.2 m,[4] which affected the coasts of the Celebes Sea, causing widespread damage. The combined effects of the earthquake and the tsunami caused 52 casualties.
The earthquake has been associated with the Cotabato Trench, the surface expression of an active east-dipping subduction zone beneath Mindanao.[5]
