"Map of faults in southern California," By Natural Hazards Mission Area Photographer, Kate Scharer, USGS Sources/Usage, Public Domain Accessed 10-20-2024 You cannot overwrite this file. File usage
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 Libre Map Project was started by Jared Benedict and around 100 additional individuals contributing money to purchase (or "liberate") a full set of 1:24K scale USGS topographic maps in Digital raster graphic form. [1] The map files were then hosted by archive.org to ensure the map data will continue to be freely available to everyone ...
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 ...
USGS map showing faults that span the Pacific–North America plate boundary. The Hayward Fault Zone is a right-lateral strike-slip geologic fault zone capable of generating destructive earthquakes. The fault was first named in the Lawson Report of the 1906 San Francisco Earthquake in recognition of its involvement in the earthquake of 1868. [1]
Portland Hills Fault using data from USGS and OpenStreetMap. Made using QGIS. The Portland Hills fault zone is the largest shallow fault that cuts beneath Portland, Oregon. [1] It stretches from Oregon City to Scappoose, and has a zone of deformation that extends at least 1,300 feet (400 m). [2]
The Little River Fault (see the QFFDB, Fault 556) is representative of an extensive zone of faults along the north side of the Olympic Peninsula and in the Strait of Juan de Fuca (likely connected with the fault systems at the south end of Vancouver Island, see fault database map), but these lie west of the crustal blocks that underlie the ...
Other regional faults such as the Washita Valley fault which runs parallel to the Meers fault may also be capable of causing earthquakes. [58] Earthquake hazard map published in 2014. The USGS national hazard map states that the Meers fault has a recurrence interval of 4,500 years [47] but estimates range from 100,000 years to 1,300 years. [14]
