The Friant-Kern Canal and the Delta-Mendota Canal are two of four projects that are being considered for repaired from subsidence damages. For example, Senate Bill 559 sought to provide over $400 million in funds to repair the Friant-Kern Canal. However, Governor Newsom vetoed the bill in search of broader state-wide solutions to subsidence ...
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, and earthquake-triggered landslide-zone ...
In 2004, a study conducted by the Geological Society of America analyzed the potential for land subsidence along the Cascadia subduction zone. It postulated that several towns and cities on the west coast of Vancouver Island, such as Tofino and Ucluelet, are at risk for a sudden, earthquake initiated, 1–2 m subsidence. [23]
Ground water was pumped heavily, leading to the Santa Clara valley being the first region recognized to be affected by land subsidence in the 1940s. [2] Between 1912 and 1966, artesian pressure levels dropped more than 200 feet (61 m). The decreasing pressure heads resulted in land subsidence of up to 15 feet (4.6 m). [3]
