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 ...
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 ...

Of the six main faults evaluated in previous studies the Southern San Andreas Fault remains the most likely to experience an M ≥ 6.7 earthquake in the next 30 years. The largest increase in such likelihood is on the Calaveras Fault (see main faults map for location), where the mean (most likely) value is now set at 25%. The old value, of 8% ...
The color-coded map – the USGS' first to include all 50 states – is meant to provide a visual to allow for geologists and engineers to prepare for the looming threats that exist to the nation ...
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]
