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.
Science failed to explain the phenomena until 1978, when geologists discovered a massive fault line running from the middle of the continent to its eastern coast. More recent magnetic surveys show that the structure is a 500-million year-old strike-slip fault, which starts under the Eastern Tennessee seismic zone and runs to the eastern coast ...
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.
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 ...
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 Ramapo Fault zone is a system of faults ... Green lines indicate the trace of the Ramapo fault. ... pre-existing faults that were formed during ancient geological ...
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 ...
Major fault at the dividing line between the Allegheny Plateau and the true Appalachian Mountains (Williamsport, Pennsylvania).The mountains formed by the Alleghanian orogeny were once rugged and high [7] [8] during the Mesozoic and late Paleozoic but in our time are eroded into only a small remnant: the heavily eroded hills of the Piedmont.
