The Marikina Valley fault system, also known as the Valley fault system (VFS), is a dominantly right-lateral strike-slip fault system in Luzon, Philippines. [2] It extends from Doña Remedios Trinidad, Bulacan in the north, running through the provinces of Rizal, the Metro Manila cities of Quezon, Marikina, Pasig, Taguig and Muntinlupa, and the provinces of Cavite and Laguna, before ending in ...
Scientists eventually realized, though, that the cause was a then-unknown fault, the Cottage Grove Fault, a small tear in the Earth's rock in the Southern Illinois Basin near the city of Harrisburg, Illinois. The fault, which is aligned east–west, is connected to the north–south-trending Wabash Valley Fault System at its eastern end. [15]
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
On the west end of Salt Lake Valley is another fault zone called the West Valley fault zone that spans 9 miles (16 km) north-northwest. Recent trench studies have shown that the West Valley fault tends to rupture simultaneously with the Wasatch Fault, compounding issues such as liquefaction, landslides and flooding.
The earthquakes this week were located slightly north of the Ortigalita fault, in an area without any mapped fault lines at the surface. Which parts of Stanislaus County are most at risk for ...
Valley fault system is the common name for fault systems in valleys and basins including: Marikina Valley fault system; Independence Valley fault system;
Strike slip offsets of over 1 m (3 ft 3 in) were recorded on the West Gate and Louderback Mountain faults, while less than 1 meter of normal faulting slip was found along the Gold King fault. [17] In Bell Flat, 3.6 meters of normal slip was measured. [8] Fault scarps of 7 meters in height were seen for 102 meters in the valley. [18]
The reported epicenter of the 2014 South Napa earthquake was located beneath the Napa Valley Marina. The West Napa Fault is a 57 km (35 mi) long geologic fault in Napa County, in the North Bay region of the San Francisco Bay Area in northern California. It is believed to be the northern extension of the Calaveras Fault in the East Bay region.
