The earthquake struck near Davao Oriental early on Thursday morning, August 12. PHIVOLCS earlier listed the earthquake as magnitude 7.3 at a depth of 69 kilometers, then revised its advisory to a magnitude 7.2 earthquake, which occurred at a depth of 50 kilometers.
This includes both faulting along the plate interfaces and within the subducting slabs. For the Philippine Trench, examples of those on the plate interface are the 1988 M w 7.3 and the 2023 M7.6 events. The 1975 M w 7.6 earthquake was caused by intra-slab normal faulting, while the 2012 M7.6 was a result of thrust faulting within the descending ...
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.
On July 6, 2017, a 6.5 magnitude earthquake hit Leyte, causing at least 4 deaths and 100 injuries. The quake also caused power interruptions in the whole of Eastern Visayas and nearby Bohol . The Philippine archipelago is located in the Pacific Ring of Fire , where earthquakes and volcanic activity are common.
The 2019 Eastern Samar Earthquake struck the islands of Visayas in the Philippines on April 23, 2019, at 1:37:51 p.m. (). [3] It had a moment magnitude of 6.5 [3] (M ww 6.4 by USGS) [4] and a local magnitude of 6.2 [5] with a max intensity of VI based on the PHIVOLCS earthquake intensity scale (PEIS). [3]
The 2017 Surigao earthquake occurred on February 10, 2017, at 10:03 PM , with a surface-wave magnitude of 6.7 off the coast of Surigao del Norte in the Philippines. According to the PHIVOLCS earthquake intensity scale the earthquake was an Intensity VII (Destructive) earthquake at maximum.
The 2019 Cotabato earthquakes were an earthquake swarm which struck the province of Cotabato on the island of Mindanao in the Philippines in October 2019. [6] Three of these earthquakes were above 6.0 on the moment magnitude scale with a Mercalli intensity of VIII. More than 40 people have been reported dead or missing and nearly 800 were ...
The PHIVOLCS earthquake intensity scale (PEIS; Filipino: Panukat ng Pagyanig ng Lindol) [1] is a seismic scale used and developed by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to measure the intensity of earthquakes. It was developed as upon a specific response to the 1990 Luzon earthquake. PHIVOLCS cites seismic scale ...
