California Landslides
Landslides in California occur mainly due to intense rainfall but occasionally are triggered by earthquakes. Landslides are common in Southern California, the San Francisco Bay Area and other parts of Northern California, and the Sierra Nevada. Although they most often are reported when they impact residential developments, landslides also damage roads, railroads, pipelines, electrical lines, and other infrastructure throughout the state, and occur in unoccupied parts of the state. California Geological Survey CGS is California's primary source of geologic and seismologic products and services for decision making by California's government agencies, its businesses and the public. Since the 1960s, when it was known as the California Division of Mines and Geology, CGS has produced many maps that depict landslide features and potential slope-failure areas. CGS products have included geologic maps and reports for land-use planning, landslide hazard identification maps, watershed maps ...

Landslides
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Automatic Deformation Monitoring System
Deformation monitoring (also referred to as deformation survey) is the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of stresses induced by applied loads. Deformation monitoring is a major component of logging measured values that may be used for further computation, deformation analysis, predictive maintenance and alarming. Deformation monitoring is primarily related to the field of applied surveying, but may also be related to civil engineering, mechanical engineering, construction, and geology. The measuring devices used for deformation monitoring depend on the application, the chosen method, and the preferred measurement interval. Measuring devices Measuring devices (or sensors) can be sorted in two main groups—geodetic and geotechnical sensors. Both measuring devices can be seamlessly combined in modern deformation monitoring. *Geodetic measuring devices measure georeferenced (relative to established locations ...

2018 South California Landslides
A series of mudflows occurred in Southern California in early January 2018, particularly affecting areas northwest of Montecito in Santa Barbara County. The incident was responsible for 23 deaths, although the body of one of the victims has never been found. Approximately 163 people were hospitalized with various injuries, including four in critical condition. The disaster occurred one month after a series of major wildfires. The conflagrations devastated steep slopes, which caused loss of vegetation and destabilization of the soil and greatly facilitated subsequent mudflows. The mudflows caused at least $177 million (2018 USD) in property damage, and cost at least $7 million in emergency responses and another $43 million (2018 USD) to clean up. Background The 2017 California wildfire season was at the time the most destructive in California's history, with approximately 9,133 wildfires that burned over and killed 46 people. At the beginning of December, the Santa Ana winds f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California State Route 1
State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At , it is the longest state route in California, and the second-longest in the US after Montana Highway 200. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge. The highway is designated as an All-American Road. In addition to providing a scenic route to numerous attractions along the coast, the route also serves as a major thoroughfare in the Greater Los Angeles Area, the San Francisco Bay Area, and several ...

Caves with ancient pictographs are located in the area around Conejo Grade including a site used for reli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Conchita, California
La Conchita (; Spanish for "The Little Shell") is a small unincorporated community in western Ventura County, California, on U.S. Route 101 just southeast of the Santa Barbara county line. The ZIP Code is 93001, and the community is inside area code 805. On January 10, 2005, a major landslide occurred in La Conchita. The 2005 landslide killed 10 people, and destroyed or damaged dozens of houses. The landslide recurred on part of a previous landslide in 1995. History "La Conchita", Spanish for little conch shell, was first used as the name of a spur on the Southern Pacific railroad line in the 1880s and it was a name generally used to describe a broader area than the present day village. During this time until 1923, the small beach settlement was named "Punta" and the street names still carried today (San Fernando, Ojai, Bakersfield, Carpinteria, etc.) commemorated the home town areas of the railroad workers who settled in the town while building the Southern Pacific line.

2005 La Conchita Landslide
The town of La Conchita, California, experienced major landslides in 1995 and 2005. The latter landslide killed 10 people, and destroyed or damaged dozens of houses. The 2005 landslide occurred on part of a previous landslide that occurred in 1995. The historic slides are part of the larger Rincon Mountain slide, which "started many thousands of years ago and will continue generating slides in the future." Setting La Conchita is a small community located on the southern California coastline between Ventura and Santa Barbara. It lies on a narrow strip of land about wide between the shoreline and abutting a high bluff. The top of the bluff was covered by avocado and citrus orchards. The bluff above La Conchita has a slope of approximately 35 degrees and consists of poorly cemented marine sediments. Geologic evidence indicates that landslides have been occurring at and near La Conchita for many thousands of years up to the present, on a geologically frequent basis. Historical a ...

1996 Yosemite Valley Landslide
The 1996 Yosemite Valley landslide occurred on July 10, 1996, near the Happy Isles trailhead in Yosemite Valley, Yosemite National Park, Mariposa County, California. 162,000 tons of rocks and other debris fell to the ground at over 160 miles per hour. Of the 12 campers /hikers involved in the incident, one was killed. The landslide competes with the 1997 Merced River flood and the 2013 Rim wildfire for the designation of the worst natural disaster in Yosemite to date. The earthquake caused by the rock slide was followed almost immediately by a sonic boom. Soon afterward a granite dust mushroom cloud formed over Happy Isles. The immense pressure created at the base of the rock slide blew down giant pine trees as if they were nothing. Afterwards the nearby campground tables and trees were covered with a thick coat of granite dust. Impacts The first impact occurred at 18:52:28.0 Pacific Daylight Time (02:52:28 UTC), and the second at 18:52:41.6 PDT (02:52:41 UTC). ...
