The USGS proposed two finite fault models: one depicting rupture on a northwest-trending fault with a shallow west-southwest dip, and the other on an east-northeast fault with a near-vertical dip. Both rupture models indicated a maximum slip of 3 m (9.8 ft). [8] Shaking was estimated to have lasted for around 30 seconds. [9]
The fault plane solution indicate a rupture source striking east–west with a north or south dip. [11] [12] On October 28, a M ww 5.0 event hit the area, [13] followed by a mb 4.8 aftershock the next day. [14] According to seismologists, these earthquakes had epicenters between the Siakhubulak Fault in the north and Herat Fault in the south.
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 ...
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 ...
1. Fault numbers and maps from USGS Quaternary Fault and Fold Database. 2. Lengths from UCERF-2, Table 4; may vary from QFFDB values. 3. Strikes (orientation) from QDFFB. 4. Slip rates from UCERF-2 Table 4; range reflects different sections. 5. Estimated probability of a M≥6.7 event in 30 years. From UCERF-2 Table 12.
The fault that ruptured beneath New Jersey on Friday morning was likely an ancient, sleeping seam in the Earth, awakened by geologic forces in a region where earthquakes are rare and seismic risks ...
ECDM map. The earthquake occurred as a result of oblique reverse and strike-slip faulting.The rupture had an area of 51 km (32 mi) × 28 km (17 mi), and occurred on either a moderately dipping oblique reverse and right-lateral fault striking east, or a steeply dipping oblique reverse and left-lateral fault striking west.

Multiple notable earthquakes have struck the United States this year, including a powerful quake in California and a historic event on the East Coast earlier in 2024. Strong earthquakes can lead ...
