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 ...
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults.
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 ...
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 ...
Most houses in the area were yaodongs—dwellings carved out of loess hillsides—and many victims were killed when these structures collapsed. The 1976 Tangshan earthquake , which killed between 240,000 and 655,000 people, was the deadliest of the 20th century.
The prediction is based on research done by dozens of scientists and engineers using seismic studies, historical geological data and new information to identify nearly 500 additional fault lines ...
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.
