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 July 15, 2011, PBS aired a 17-minute video documenting the controversy over the discovery of the Shoreline fault. [10] It details the differences of opinion between PG&E and a USGS geologist who disagrees with PG&E's assessment of the length of the Shoreline fault, and the potential for shaking should slippage occur at the Hosgri/Shoreline ...
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 ...
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.
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
Both faults are active, cause earthquakes every 600 to 900 years, and could cause ground slippage of up to 9.8 feet (3.0 m). [2] An earthquake in 1882 caused a regional tsunami . [ 1 ] A team of seismologists led by Tom Rockwell of San Diego State University found evidence suggesting both faults slipped simultaneously around 700 CE.
The 800-mile San Andreas Fault is one of the largest fault lines in the world. A meeting of the North American and Pacific tectonic plates, this transform fault (where two tectonic plates move ...
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 ...
