A study that examines the newly named Salton Trough Fault appeared in the Bulletin of the Seismological Society of America this week.The researchers reveal that they detected a 3.5-magnitude earthquake in Gilroy, a city in Northern California, in March 2018. They also discovered a new fault system at the bottom of the ocean. The technology could eventually help them map fault lines in areas where scientists know very little about seismic activity on the ocean floor.Here, we use morphometric analyses and 10 Be catchment-averaged erosion rates, together with reverse slip rates from the Sierra Madre−Cucamonga fault zone, to reveal patterns in uplift, erosion, and fault activity in the range front of the San Gabriel Mountains in southern California, USA.

The USGS created a …Combined with the observation that short-term geodetic and longer-term geologic rates covary on major southern California fault systems, this suggests that either (1) a temporal cluster of seismic displacements on upper-crustal faults increases ductile deformation on their downward extensions, or (2) rapid ductile slip in the lower crust ...The Elsinore Fault is a major strand of the complex fault system in Southern California that also includes the San Andreas, San Jacinto, Inglewood-Newport-Rose Canyon, and numerous other faults (Figure 1). This website is intended for educational exploration of the landscape features associated with the Elsinore Fault. More recent …Orientations of active antithetic faults can provide useful constraints on in situ strength of the seismogenic crust. We use LINSCAN, a new unsupervised learning algorithm for identifying quasi-linear clusters of earthquakes, to map small-scale strike-slip faults in the Anza-Borrego shear zone, Southern California.

The Mother Lode gold-quartz veins and deposits also change in character from south to north, reflecting the lithologic and structural changes along the Melones fault zone. In the southern and central districts, the veins are in brittle faults which cut the serpentinite-hosted melange and its footwall or hanging wall. Faults of Southern California. Los Angeles Region.
