The earthquake came from an area that produced a similar sequence of earthquakes in October 2019 and December 2019 [citation needed], within an active faulting zone known as the Cotabato fault system, which includes the NW-SE trending Makilala-Malungon, M'lang, North and South Columbio and Tangbulan faults, and the SW-NE trending Makilala and ...
Largest. Mw 8.3 1918 Celebes Sea earthquake. Deadliest. M w 8.0 1976 Moro Gulf earthquake 5,000–8,000 killed. The Philippines lies within the zone of complex interaction between several tectonic plates, involving multiple subduction zones and one large zone of strike-slip, all of which are associated with major earthquakes.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS, Tagalog: [ˈfivolks]; Tagalog: Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya[2]) is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily ...
These active plate boundaries lead to high seismic activity. Since 1970, 11 other earthquakes of magnitude 6.5 or larger have occurred within 250 km (155 mi) of the July 27, 2022, earthquake. The largest of these earthquakes was a magnitude 7.7 strike-slip earthquake on July 16, 1990, located approximately 215 km (134 mi) south of the July 27 ...
A magnitude 6.5 earthquake struck Papua New Guinea on March 11 at a depth of 28.9 km (18.0 mi). [41][42] A magnitude 6.1 earthquake struck the South Sandwich Islands on March 19 at a depth of 31.3 km (19.4 mi) [43] A magnitude 6.1 earthquake struck Fiji on March 24 at a depth of 10 km (6.2 mi).
However, PHIVOLCS said that it was a separate earthquake. [10] On August 2, 2024, two M ww 6.8 and 6.3 earthquakes occurred within the area of the 2023 sequence. [11] [12] The December 2 earthquake was described as the first major earthquake in the area since a doublet 7.1 and 7.5 earthquake that also produced a tsunami in 1992. [13]
1 dead. On August 12, 2021, at 01:46:12 PST, a strong M w 7.1 earthquake struck the island of Mindanao at a depth of 55.1 kilometers (34.2 mi). It had a maximum perceived Intensity V on the PHIVOLCS Earthquake Intensity Scale. [1] No damage or injuries were reported but a young man was killed by the earthquake.
United States Geological Survey shake map for the 2019 Luzon earthquake; a maximum Mercalli intensity scale value of 6.6 was observed in Gutad, Floridablanca, Pampanga. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) initially reported an earthquake of magnitude 5.7 striking at 17:11 PST with an epicenter two kilometers N 28° E of Castillejos, Zambales.
