Mount Breakenridge
Mount Breakenridge, , is a mountain in the Lillooet Ranges of southwestern British Columbia, Canada, located on the east side of upper Harrison Lake in the angle of mountains formed by that lake and the Big Silver River. Name The name was conferred by Lieutenant Palmer RE for Archibald T. Breakenridge RE, a member of his party, during a reconnaissance survey by the Royal Engineers from the north end of Harrison Lake to Four Mile House in the Douglas Road along the Lillooet River in 1859. In Ucwalmícwts, the language of the Lower Lillooet people, the mountain's name is ''mólkwcen'' (no translation given), which is also the name of a fishing camp located near the mouth of Stokke Creek, a creek feeding Harrison Lake from its origins on the flank of Breakenridge. Potential landslide and tsunami hazard Mount Breakenridge is the subject of intensive study by government geologists due to the location of a fracture or shear zone on the mountainside above Harrison Lake.

NASA World Wind
NASA WorldWind is an open-source (released under the NOSA license and the Apache 2.0 license) virtual globe. According to the website (https://worldwind.arc.nasa.gov/), "WorldWind is an open source virtual globe API. WorldWind allows developers to quickly and easily create interactive visualizations of 3D globe, map and geographical information. Organizations around the world use WorldWind to monitor weather patterns, visualize cities and terrain, track vehicle movement, analyze geospatial data and educate humanity about the Earth." It was first developed by NASA in 2003 for use on personal computers and then further developed in concert with the open source community since 2004. As of 2017, a web-based version of WorldWind is available online. An Android version is also available. The original version relied on .NET Framework, which ran only on Microsoft Windows. The more recent Java version, WorldWind Java, is cross platform, a software development kit (SDK) a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it mig ...

Hot Springs Cove
Hot Springs Cove, formerly Refuge Cove, is an unincorporated settlement on Sydney Inlet on the west side of the Openit Peninsula in the western Clayoquot Sound region of the West Coast of Vancouver Island. Hot Springs Cove derives its name from its proximity to Ramsay Hot Springs, and is protected by Maquinna Marine Provincial Park. The post office at Hot Springs Cove was closed in 1974 but had operated since 1947, when it was first named Sydney Inlet until being renamed in 1948. Despite the closure of the post office, there remains a year-round population in the vicinity.

Tofino
Tofino ( ) is a town of approximately 2,516 residents on the west coast of Vancouver Island in the Canadian province of British Columbia. The District of Tofino is located at the western terminus of Highway 4 on the tip of the Esowista Peninsula at the southern edge of Clayoquot Sound. It is situated in the traditional territory of the Tla-o-qui-aht First Nations. A popular year-round tourism destination, Tofino's summer population swells to many times its winter size. It attracts surfers, hikers, nature lovers, bird watchers, campers, whale watchers, fishers, or anyone just looking to be close to nature. Despite its small population, the town attracts a number of chefs and culinary professionals, which has resulted in a burgeoning choice of restaurants and specialty shops. In the winter, it is not as bustling, although many people visit Tofino and the West Coast to watch storms on the water. Close to Tofino is Long Beach, a scenic and popular year-round destination, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1960 Valdivia Earthquake
The 1960 Valdivia earthquake and tsunami ( es, link=no, Terremoto de Valdivia) or the Great Chilean earthquake (''Gran terremoto de Chile'') on 22 May 1960 was the most powerful earthquake ever recorded. Various studies have placed it at 9.4–9.6 on the moment magnitude scale. It occurred in the afternoon (19:11 GMT, 15:11 local time), and lasted for approximately 10 minutes. The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands. The epicenter of this megathrust earthquake was near Lumaco, approximately south of Santiago, with Valdivia being the most affected city. The tremor caused localised tsunamis that severely battered the Chilean coast, with waves up to . The main tsunami traveled across the Pacific Ocean and devastated Hilo, Hawaii, where waves as high as were recorded over from the epicenter. The death toll and monetary losses arising from this widespread disaster are n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1700 Cascadia Earthquake
The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate from mid-Vancouver Island, south along the Pacific Northwest coast as far as northern California. The length of the fault rupture was about , with an average slip of . The earthquake caused a tsunami which struck the west coast of North America and the coast of Japan. Japanese tsunami records, along with reconstructions of the wave moving across the ocean, put the earthquake at about 9pm on the evening of 26 January 1700. Evidence The earthquake took place at about 21:00 Pacific Time on January 26, 1700 ( NS). Although there are no written records for the region from the time, the timing of the earthquake has been inferred from Japanese records of a tsunami that does not correlate with any other Pacific Rim quake. The Japanese records exist primarily in the modern-day Iwate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Succession
Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil. Many factors can affect secondary succession, such as trophic interaction, initial composition, and competition-colonization trade-offs. The factors that control the increase in abundance of a species during succession may be determined mainly by seed production and dispersal, micro climate; landscape structure (habitat patch size and distance to outside seed sources); bulk density, pH, and soil texture (sand and clay). Secondary succession is the ecological succession that occurs after the initial succession has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harrison River
The Harrison River is a short but large tributary of the Fraser River, entering it near the community of Chehalis, British Columbia, Canada. The Harrison drains Harrison Lake and is the ''de facto'' continuation of the Lillooet River, which feeds the lake. The Harrison is navigable, although in the days of the Fraser Canyon Gold Rush of it was necessary to dredge the sandbars at the confluence with the Fraser, which were known as "the Riffles", and also as "the Falls of the Harrison". Dredging of these shallows was needed to make the river navigable to Harrison Lake, at the north end of which the townsite of Port Douglas was established as the port for the Douglas Road to Lillooet in the upper Fraser Canyon, in order to bypass hostile territory in the lower Canyon (see Fraser Canyon War). There are also small rapids and difficult water in the first stretch of the river downstream from Harrison Lake, which is a forested canyon. Below the confluence of the Chehalis River, a ...
