The Bohol fault system is a reverse fault system in Bohol province, Philippines. This fault system contains three segments: the newly found North Bohol Fault following the 2013 Bohol earthquake, [2] the South Offshore Fault, [3] and the East Bohol Fault. The North Bohol Fault is located in Inabanga and near Clarin.
The 2013 Bohol earthquake occurred on October 15 at 8:12:31 PST in Bohol, an island province located in Central Visayas, Philippines. [9] The magnitude of the earthquake was recorded at M w 7.2, its epicenter in the vicinity of 6 kilometres (3.7 mi) S 24° W of Sagbayan, and its depth of focus at 12 kilometres (7.5 mi).
On Luzon, the fault zone splays out into a number of different faults, including the Digdig Fault. One of the largest historical earthquake on the fault zone was the 1990 Luzon M s 7.8 event that left nearly 2,000 people dead or missing. The same part of the fault zone is thought to have ruptured in the 1645 Luzon earthquake. [7]
Offshore Cebu-Bohol faults (?) – occasional occurrence of low to moderate magnitude, shallow-seated earthquakes between Cebu and Bohol, some capable of causing significant damage to infrastructure, is the subject of current discussions on the possible existence of active faults in the region. Such earthquake generators are most likely ...
The Bohol Sea is home to segments of the Philippine fault system, a system of fault line extending from the Northwestern province of Ilocos Sur, transversing through Quezon province, Masbate Island and the Eastern Visayas region, and ending at the end of Davao Gulf. The fault that had ruptured suggested a northeast–southwest trending nodal plane.
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
A newly found fault line with a rare slanted angle shows why an earthquake rattled New York City in April harder than its epicenter in New Jersey — and may be a bigger seismic activity threat ...
