A damaging earthquake affecting New York City in 1884 was incorrectly argued to be caused by the Ramapo fault, likely because it is the most prominent mapped fault in the greater New York City area. At the present, the relationship between faults and earthquakes in the New York City area is understood to be more complex than any simple ...
In top figure, closed red circles show 1924–2006 epicenters. Open black circles show larger earthquakes of 1737, 1783 and 1884. Green lines are the Ramapo fault. Seismicity of the New York City area is relatively low. [1] New York is less seismically active than California because it is far from any plate boundaries.
These are the six geologic faults in California with sufficient data to use a stress-renewal model for estimating the probability of an M ≥ 6.7 earthquake within the next 30 years. The Hayward fault zone and Rodgers Creek fault are treated as a single fault; the San Andreas fault is treated as two sections.
The foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse Range. Faults in the upper left are part of the Eastern California Shear Zone, connecting northward with the Walker Lane region. Faults extend deeper than shown. Cumulative energy released by all earthquakes in Southern California from 1932 through July ...
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
There is a 70% probability that one of these faults will generate a 6.7 M w or greater earthquake before 2030, including the Hayward Fault Zone, which has gone beyond its average return period of 130 years (156 years ago as of December 2024).
Last earthquake ca. 1717 (~M8) [2] Altyn Tagh Fault: 2000: Tibetan Plateau/Tarim Basin: Sinistral strike-slip: Active [3] Amfilochia Fault: 60: Western Greece: Sinistral strike-slip: Active: Amorgos Fault >100: Greece, South Aegean Sea: Normal: Active: 1956 Amorgos (M7.4) [4] Arkitsa–Agios Konstantinos fault zone: 25: Central Greece: Normal ...
The fault zone responsible for Thursday's 7.0 magnitude earthquake off the coast of California is not known to produce large tsunamis, but due to the size of the event, NOAA’s Tsunami Warning ...
