The Sierra Madre Fault Zone highlighted in red. Situated at the boundary to the San Gabriel Valley and San Fernando Valley, the Sierra Madre Fault Zone (also known as the Sierra Madre-Cucamonga Fault) runs along the southern edge of the San Gabriel Mountains for a total of 95 kilometers (59 mi), where the northwesternmost 19 km (12 mi) comprises the San Fernando Fault (the section responsible ...3.

R esearchers said they have found a new, underwater fault line in southern California that runs along the Salton Sea and parallel to the San Andreas Fault. A study ...Brown lines are known hazardous faults and fault zones. Magnitude = ? for new earthquakes until a magnitude is determined (takes 4-5 minutes). Maps are updated within 1-5 minutes of an earthquake or once an hour. (Smaller earthquakes in southern California are added after human processing, which may take several hours.)

Owing to wiggles in the fault line, portions of the thin red lines can be more than 100 ft from the fault. By presenting the San Andreas Fault map as interactive web-based imagery, anyone can pinpoint the fault anywhere along its trace. And by using a thin red line, the underlying landscape features are minimally obscured.The 230 km long San Jacinto fault zone (SJFZ) is the most seismically active component of the plate boundary system in Southern California over the last several decades (Hauksson et al. 2012), and is subparallel to the southern San Andreas fault to the NE and the Elsinore fault to the SW (Fig. 1a).Residents throughout California are on edge after two massive earthquakes— a magnitude 6.4 and 7.1, rocked Southern California less than two days apart and triggered a series of aftershocks.

The Great Southern California ShakeOut earthquake drill is based on a magnitude 7.8 scenario earthquake on the San Andreas fault in southern California. This portion of the San Andreas fault has been identified as the most likely source of a very large earthquake in California (Working Group on California Earthquake Probabilities).As part of the earthquake drill, computer simulations of the ...The Quake Tracker displays quakes from the past 30 days with magnitudes above 3.0 in Northern California, 4.0 in Southern California, 5.0 in the United States, and 7.0 in North America.

The new fault appears to run right through the 56-km-long Salton Sea in the ...Brown lines are known hazardous faults and fault zones. Magnitude = ? for new earthquakes until a magnitude is determined (takes 4-5 minutes). Maps are updated within 1-5 minutes of an earthquake or once an hour. (Smaller earthquakes in southern California are added after human processing, which may take several hours.)This overview map above shows the location of the MASTER flight lines for the Southern California Faults (SCF) project. It links to a larger version of the overview map. Most faults have both daytime and nighttime MASTER data pairs. Daytime flightlines are represented by solid lines, nighttime flightlines by dashed lines; lines are offset from ...

The northern San Andreas leveled San Francisco in 1906, but it’s been a lot longer since the southern part of the fault ruptured. On average, Southern California has seen big quakes every 110 to 140 years, based on records of past earthquakes and studies of earthquake faults. The last big quake near Los Angeles, a magnitude 7.9, struck Fort ...

Owing to wiggles in the fault line, portions of the thin red lines can be more than 100 ft from the fault. By presenting the San Andreas Fault map as interactive web-based imagery, anyone can pinpoint the fault anywhere along its trace. And by using a thin red line, the underlying landscape features are minimally obscured.

It turns out two separate faults in Southern California really aren't separate after all. A new study discovered the Newport-Inglewood and Rose Canyon faults, the majority of which are just off the coast of Southern California, are really just one continuous fault system. And it's capable of producing an up to 7.4 magnitude earthquake. The fault runs from Los Angeles to San Diego, and while ...The re-identified fault, which includes the Newport-Inglewood and Rose Canyon lines, runs between Los Angeles and San Diego could set off a 7.4 magnitude earthquake, according to a report issued ...LIST OF MAJOR ACTIVE SURFACE FAULTS IN SOUTHERN CALIFORNIA.

Ground shaking is the most powerful predictor of damage from an earthquake. The U.S. Geological Survey (USGS) National Seismic Hazard Map shows the strength of ground shaking that has a 1 in 50 chance of being exceeded in a particular place in the lower 48 states over a period of 50 years.
