1978 Santa Barbara Earthquake
The 1978 Santa Barbara earthquake (also known as the Goleta earthquake), occurred on August 13, 1978, 3:54 p.m. (Pacific Time Zone, PDT) with its epicenter beneath the Santa Barbara Channel. The magnitude of the earthquake was estimated at 5.1 according to the Southern California Seismic Network; however, it may have been as high as 5.6 . There were no deaths from the event; however, 65 people sustained mild to moderate injuries. Tectonic Setting Santa Barbara, California, Santa Barbara is part of California, which is known for its very high level of seismic activity, the second highest in all of the United States only behind Alaska. The Santa Barbara area is affected by numerous faults, inland within the mountainous ridges on the Santa Ynez Range down to the coastal plains and beneath the Santa Barbara Channel. The Santa Barbara Channel lies within the Transverse Ranges block where the transform fault, transform boundary between the North American Plate, North American and Paci ...

Pacific Time Zone
The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time ( UTC−08:00). During daylight saving time, a time offset of UTC−07:00 is used. In the United States and Canada, this time zone is generically called the Pacific Time Zone. Specifically, time in this zone is referred to as Pacific Standard Time (PST) when standard time is being observed (early November to mid-March), and Pacific Daylight Time (PDT) when daylight saving time (mid-March to early November) is being observed. In Mexico, the corresponding time zone is known as the ''Zona Noroeste'' (Northwest Zone) and observes the same daylight saving schedule as the U.S. and Canada. The largest city in the Pacific Time Zone is Los Angeles, whose metropolitan area is also the largest in the time zone. The zone is two hours ahead of the Hawaii–Ale ...

Fold (geology)
In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets (known as ''fold trains''). Synsedimentary folds are those formed during sedimentary deposition. Folds form under varied conditions of stress, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (''fault bend fold''), at the tip of a propagating fault (''fault propagation fold''), by differential compaction or due ...

List Of Earthquakes In California
The earliest known California earthquake was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also documented earthquakes. As Spanish missions were constructed beginning in the late 18th century, earthquakes records were kept. After the missions were secularized in 1834, records were sparse until the California Gold Rush in the 1840s. From 1850–2004, there was about one potentially damaging event per year on average, though many of these did not cause serious consequences or loss of life. Since the three damaging earthquakes that occurred in the American Midwest and the East Coast ( 1755 Cape Ann, 1811–12 New Madrid, 1886 Charleston) were well known, it became apparent to settlers that the earthquake hazard was different in California. While the 1812 San Juan Capistrano, 1857 Fort Tejon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Derailment
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard. A derailment of a train can be caused by a collision with another object, an operational error (such as excessive speed through a curve), the mechanical failure of tracks (such as broken rails), or the mechanical failure of the wheels, among other causes. In emergency situations, deliberate derailment with derails or catch points is sometimes used to prevent a more serious accident. History The first recorded train derailment in history is known as the Hightstown Rail Accident in New Jersey that occurred on November 8, 1833. The train was traveling between Hightstown and Spotswood New Jersey and derailed after an axle broke on one of the carriages as a result of a journal box catching fire. The derailment resulted i ...

Freight Train
Rail freight transport is the use of rail transport, railroads and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of Railroad car#Freight cars, freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics, logistics chain. Trains may haul bulk material handling, bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled per unit of energy consumed, rail transport Fuel efficiency in transportation#Trains, can be more efficient than other means of transportation. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Barbara Municipal Airport
Santa Barbara Municipal Airport is west of downtown Santa Barbara, California, United States. SBA covers 948 acres (384 ha) of land and has three runways. It is near the University of California, Santa Barbara, and the city of Goleta. The airport was annexed to the city of Santa Barbara by a long, wide corridor, mostly under the Pacific Ocean (a shoestring annexation). Most of the airport is above sea level and borders a wetland area, the Goleta Slough. In 2019, the airport was categorized as a ''small hub primary airport'' by the Federal Aviation Administration (FAA), with 510,141 enplanements. As of May 2021, the airport is served by Alaska Airlines, American Airlines, Southwest Airlines and United Airlines. History Early years Aviation in the area began in 1914 when Lincoln J. Beachey flew an airplane across Goleta Valley. Two years later the Loughead brothers, who later changed their name to Lockheed, established a seaplane factory on State Street ( Alco ...

San Marcos Pass
San Marcos Pass (Chumash: ''Mistaxiwax'') is a mountain pass in the Santa Ynez Mountains in southern California. It is traversed by State Route 154. The pass crosses the Santa Ynez through a southwestern portion of Los Padres National Forest, and connects Los Olivos (and the Santa Ynez Valley) with Santa Barbara, California along the Pacific coast. The road has been designated as a daylight-headlight highway by the California Highway Patrol and Caltrans because of frequent accidents, particularly around the exit for Lake Cachuma. Geography The pass is one of three passages across the steep Santa Ynez Mountains, and the nearest to Santa Barbara. The Painted Cave community and Laurel Springs Ranch near Chumash Painted Cave SHP is four miles east of San Marcos Pass via East Camino Cielo Road, which intersects with SR 154 right at the summit. San Marcos Pass is a shorter but hillier alternative to using Highway 101 through Gaviota Pass. "Battle" of Fremont's Pass No shots we ...

California State Route 154
State Route 154 (SR 154) (also known as the Chumash Highway or unofficially as San Marcos Pass Road after the signage) is a state highway in the U.S. state of California that runs from Los Olivos to Santa Barbara, crossing the San Marcos Pass in the Santa Ynez Mountains. Before U.S. Route 101 was built through the Gaviota Pass, SR 154 was the main throughway to Santa Barbara and the tri city area including use as a stagecoach route in early years. After being replaced by US 101 as the primary route between the Santa Ynez Valley and Santa Barbara, SR 154 now serves as a scenic bypass. Route description It is a 2 lane road with some passing lanes, with the highest altitude being 2000 ft. It rivals US 101 for traffic, but it goes through the Los Padres National Forest and the San Marcos Pass. It starts in Los Olivos as a spur from US 101, goes through the town, and then the end of SR 246 at Santa Ynez. It then reaches Lake Cachuma and passes through the Los Padres ...

Rockslide
A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses ''en masse'' and not in individual blocks. Note that a rockslide is similar to an avalanche because they are both slides of debris that can bury a piece of land. While a landslide occurs when loose dirt or sediment falls down a slope, a rockslide occurs only when solid rocks are transported down slope. The rocks tumble downhill, loosening other rocks on their way and smashing everything in their path. Fast-flowing rock slides or debris slides behave similarly to snow avalanches, and are often referred to as rock avalanches or debris avalanches. Definition The term landslide refers to a variety of mass wasting Mass wasting, also known as mass movement, is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike-slip
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can bl ...
