It originated near the Cotabato Trench, a zone of deformation situated between the Philippine Sea plate and the Sunda plate, and occurred very near to the Philippines' strongest earthquake for the 20th century, the 1918 Celebes Sea earthquake. The entire country is characterized by a high level of volcanic and seismic activity. The earthquake was responsible for 15 deaths and roughly 100 injuries. Up to 800 buildings were damaged as a result, many from flooding generated by landslides near Mount Parker and falling debris. Like the 1918 event, a tsunami soon followed.

Tectonic activity in the country includes both earthquakes and volcanic eruptions. Because of subduction of the Eurasian plate to the west, volcanic activity occurs along the Manila Trench and the Sulu Trench, often of powerful caliber. 13 percent of recorded eruptions in the Philippines have been deadly, as the country is responsible for the world's most deaths in volcanic eruptions.http://volcano.oregonstate.edu/vwdocs/volc_images/southeast_asia/philippines/tectonics.html Tectonics and Volcanoes of the Philippines Oregon State University Volcano World 2010 May 31, 2010 July 18, 2010 https://web.archive.org/web/20100718160024/http://volcano.oregonstate.edu/vwdocs/volc_images/southeast_asia/philippines/tectonics.html dead Seismicity as well has been powerful: in the last 50 years, more than half of the country's major earthquakes have reached magnitude 7.0 or greater. The earliest known major shock was in 1976, killing some 8,000 people. The 2002 event was the fourth of seven major events since 1976.https://earthquake.usgs.gov/earthquakes/world/historical_country.php#philippines United States Geological Survey Historic World Earthquakes November 23, 2009 May 31, 2010 dead https://web.archive.org/web/20100728221758/http://earthquake.usgs.gov/earthquakes/world/historical_country.php July 28, 2010 Earthquake With a moment magnitude (w) of 7.5, the earthquake was the sixth strongest of the year.https://neic.usgs.gov/neis/eq_depot/2002/2002_stats.html Magnitude 7 and Greater Earthquakes in 2002 United States Geological Survey December 1, 2003 May 31, 2010 https://web.archive.org/web/20120218052601/http://neic.usgs.gov/neis/eq_depot/2002/2002_stats.html February 18, 2012 dead It occurred in a zone of geologic deformation along the Sunda and Philippine Sea Plates, as the result of shallow oblique-reverse faulting within the Sunda Plate. Focal mechanism solutions indicate that the earthquake rupture occurred on either a moderately dipping, southeast-striking fault, or on a thrust fault dipping shallowly towards the northeast. Of these two possible fault orientations, finite-fault modeling of globally recorded seismic data is more consistent with slip on the northwest-striking thrust fault. It had a rupture area of 200 km mi x 85 km mi, extending from Datu Blah T. Sinsuat in Maguindanao del Norte to Glan in Sarangani, with a maximum slip of 1.871 m ft near the hypocenter. The observed source time function gives a 30 second duration for the earthquake, with the greatest phase of seismic moment release occurring about 10 seconds after initiation. The earthquake had a maximum intensity of IX (Violent) on the Modified Mercalli intensity scale. On the PHIVOLCS earthquake intensity scale, intensity IX (Devastating) was registered at Palimbang, while VIII (Very destructive) was assigned to Maitum and Kiamba, and VII (Destructive) at Alabel, General Santos City and Lake Sebu. According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), 359 aftershocks were recorded by March 15, of which 11 were felt.

The most powerful aftershock measured w 6.0, and occurred at 18:27 UTC on March 8. Most of these aftershocks occurred southeast of the mainshock's epicenter. Damage and casualties Killing 15 people and injuring roughly 100 more, the earthquake affected about 800 homes throughout the southern and central parts of Mindanao. At least 33 of the damaged homes completely collapsed, while seven bridges, 36 school buildings, one hospital, two health centres, and 17 public buildings were also damaged.Philippines - Earthquake OCHA Situation Report No. 2 https://reliefweb.int/report/philippines/philippines-earthquake-ocha-situation-report-no-2-0 8 March 2002 26 April 2025 ReliefWeb OCHA Two people in Lake Sebu were killed when their house collapsed, while two others were killed by collapsing buildings in Maitum, and four people, including one each from Tacurong City and Davao City, died of cardiac arrests. One man was also fatally electrocuted by a power line damaged by the earthquake. As it is a superstition among Muslims to fire guns during earthquakes to drive away evil spirits, one death and one injury were both accidentally caused by earthquake-related gunfire in Cotabato City.Quake kills 11, wrecks buildings in Philippines https://reliefweb.int/report/philippines/quake-kills-11-wrecks-buildings-philippines 6 March 2002 26 April 2025 Reuters The earthquake spawned landslides in South Cotabato which flowed through the crater lake on Mount Parker, causing widespread flooding which swept away homes, affected at least nine sub-districts of the province and killed three people.http://www.inq7.net/nat/2002/mar/07/nat_3-2.htm https://web.archive.org/web/20020417105350/http://www.inq7.net/nat/2002/mar/07/nat_3-2.htm dead April 17, 2002 12 dead in Mindanao earthquake March 16, 2002 November 12, 2022 Philippine Daily Inquirer The landslide and subsequent flooding also created local tsunamis reaching a maximum height of 3 m ft 0 us at Kiamba, Maitum and Palimbang.https://earthquake.usgs.gov/earthquakes/eqarchives/poster/2002/20020305.php Poster of the Mindanao, Philippines Earthquake of 05 March 2002 – Magnitude 7.5 United States Geological Survey October 19, 2009 May 29, 2010 https://web.archive.org/web/20100213021243/http://earthquake.usgs.gov/earthquakes/eqarchives/poster/2002/20020305.php February 13, 2010 dead The earthquake was powerful enough to knock over concrete walls and fences.Strong earthquake rocks southern Philippines, killing four people, injuring 15 and cutting power Associated Press March 6, 2002 One major road was heavily damaged by the shaking.https://news.google.com/newspapers?id=kpcRAAAAIBAJ&sjid=jewDAAAAIBAJ&pg=4874,197748 https://archive.today/20120713101917/http://news.google.com/newspapers?id=kpcRAAAAIBAJ&sjid=jewDAAAAIBAJ&pg=4874,197748 dead July 13, 2012 Members safe after earthquake March 16, 2002 May 31, 2010 The Deseret News In Tupi, two churches were damaged.
