1927 Lompoc Earthquake
The Lompoc earthquake of 1927 occurred at 5:49 a.m. Pacific Standard Time (PST), on November 4 with an epicenter off the coast of Lompoc, Santa Barbara County in Southern California. It is one of the largest earthquakes to have occurred off the coast of California, measuring a surface-wave magnitude of 7.3. The earthquake may have originated along the Hosgri Fault, an entirely offshore structure. Shaking from the earthquake and an unusually large tsunami caused some damage to communities near the earthquake. Due to its location and the area being sparsely populated at the time, there were no human fatalities reported. It is the only California-generated tsunami recorded in Hawaii. Geology The San Simeon- Hosgri Fault is an approximately 140 km long, complex thrust or reverse fault that runs offshore, with an 18 km section that is on land. The fault has an almost north-south strike and east dip. It is a system of interlaced and parallel faults that form this str ...

2011 Tōhoku Earthquake And Tsunami
The occurred at 14:46 JST (05:46 UTC) on 11 March. The magnitude 9.0–9.1 (M) undersea megathrust earthquake had an epicenter in the Pacific Ocean, east of the Oshika Peninsula of the Tōhoku region, and lasted approximately six minutes, causing a tsunami. It is sometimes known in Japan as the , among other names. The disaster is often referred to in both Japanese and English as simply 3.11 (read in Japanese). It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900.

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest prot ...

Rossi–Forel Scale
The Rossi–Forel scale was one of the first seismic scales to represent earthquake intensities. Developed by Michele Stefano Conte de Rossi of Italy and François-Alphonse Forel of Switzerland during the late 19th century, it was used commonly for about two decades until the introduction of the Mercalli intensity scale in 1902. The Rossi–Forel scale and/or its modifications is still used in some countries, such as the Philippines until 1996 when it was replaced by the PHIVOLCS Earthquake Intensity Scale. Scale The 1873 version of the Rossi–Forel scale had 10 intensity levels: See also *Richter magnitude scale The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 ... * Seismic intensity scales * Seismic magnitude scales Bibliography * Seismic intensity scales {{Sei ...

Surf, California
Surf is an unincorporated area of Santa Barbara County, California, located along the Pacific coast within a publicly accessible area of Vandenberg Space Force Base west of the city of Lompoc. The site originally was established as a railroad town, with its growth peaking after Vandenberg was established in 1941. Since 2000 the site has just consisted of Surf Beach and the unstaffed Lompoc–Surf Amtrak Station. California State Route 246 used to run to Surf, but in 1984 the highway was truncated at Lompoc and the road from Lompoc to Surf is designated West Ocean Avenue. Sections of Surf Beach are closed between March 1 and September 30 every year during the nesting season of the western snowy plover. The affected areas may be opened earlier than September 30 if all the newly hatched birds reach their fledgling stage beforehand. The closures are in place to protect the bird under the Endangered Species Act. If a set number of trespass violations have been reached during any n ...

Chimney
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the '' flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term '' smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of ...

Flue
A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors. Historically the term flue meant the chimney itself. In the United States, they are also known as vents for boilers and as breeching for water heaters and modern furnaces. They usually operate by buoyancy, also known as the stack effect, or the combustion products may be 'induced' via a blower. As combustion products contain carbon monoxide and other dangerous compounds, proper 'draft', and admission of replacement air is imperative. Building codes, and other standards, regulate their materials, design, and installation. Heat retention Flues are adjustable and are designed to release noxious gases to the atmosphere. They often have the disadvantageous effect of releasing useful household heat to the atmosphere when not properly set—the very opposite of why the fire was lit in the first place. Fireplaces are one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Bárbara District
Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring children gifts during the late evening and overnight hours on Christmas Eve of toys and candy or coal or nothing, depending on whether they are "naughty or nice". In the legend, he accomplishes this with the aid of Christmas elves, who make the toys in his workshop, often said to be at the North Pole, and flying reindeer who pull his sleigh through the air. The modern figure of Santa is based on folklore traditions surrounding Saint Nicholas, the English figure of Father Christmas and the Dutch figure of ''Sinterklaas''. Santa is generally depicted as a portly, jolly, white-bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, red hat with white fur, and black leather belt and boots, carrying a bag full of gifts for chil ...

Landslide
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] |
