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 ...
When the location of these offsets were plotted on a map, he noted that they made a near perfect line on top of the fault he previously discovered. He concluded that the fault must have been the origin of the earthquake. This line ran through San Andreas Lake, a sag pond. The lake was created from an extensional step over in the fault, which ...
Tectonic map of the Alps, the Engadine Line is marked with "L.E." The Engadine Line is an over 50 kilometres (30 mi) long [1] northeast-trending fault in southeastern Switzerland. [2] It was originally discovered in 1896 and named "Engadiner Spalte". [3]
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
The fault was named Charlie fracture zone after the USCG Ocean Weather Station Charlie at , athwart the In July 1968 USNS Josiah Willard Gibbs (T-AGOR-1) conducted a more extended survey. [ 7 ] It was proposed that the fracture zone be renamed Gibbs fracture zone, as fracture zones are generally named for research vessels.
The 800-mile San Andreas Fault is one of the largest fault lines in the world. ... ancient Lake Cahuilla affected the fault line, and discovered two primary impacts. First, ...
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 ...
In 1940, Harold Wellman found that the Southern Alps were associated with a fault line approximately 650 km (400 miles) [a] long. [34] The fault was officially named the Alpine Fault in 1942 as an extension of a previously mapped structure. [5] At the same time, Harold Wellman proposed the 480 kilometres (300 mi) lateral displacement on the ...
