Paleotsunami
A paleotsunami is a tsunami that occurs prior to written history where there are no documented observations. Paleotsunamis are evidenced by modern technology and scientific research. One of the largest was a megatsunami resulting from the Chicxulub crater, asteroid that wiped out the dinosaurs. Studying paleotsunamis is an emerging science to identify and interpret paleotsunami deposits. There are several recorded paleotsunami records, though some are known only by historical mentions, such as tsunamis resulting from the 1700 Cascadia earthquake which is known only from oral traditions among the Native Americans of the Pacific Northwest and simultaneous 1700 Cascadia earthquake#Japanese records, Japanese accounts of the same event. Historical occurrences Chile On the coast of Chile, boulders have been found that "suggest directionality from sea to land," and they "could not be transported by rolling." On the northern Chilean coast, probable evidence of a tsunami exist as one ...

Storegga Slide
The three Storegga Slides () are amongst the largest known submarine landslides. They occurred at the edge of Norway's continental shelf in the Norwegian Sea, approximately 6225–6170 BCE. The collapse involved an estimated length of coastal shelf, with a total volume of of debris, which caused a paleotsunami in the North Atlantic Ocean. Description Storegga ( Norwegian: ''Great Edge'') is located at the edge of Norway's continental shelf in the Norwegian Sea, north-west of the Møre coast. In around 6200 BCE, structural failures of the shelf caused three underwater landslides, which triggered very large tsunamis in the North Atlantic Ocean. The collapses involved an estimated length of coastal shelf, with a total volume of of debris. Based on carbon dating of plant material recovered from sediment deposited by the tsunamis, the latest incident occurred around 6225–6170 BCE. In Scotland, traces of the subsequent tsunami have been recorded, with deposited sediment bei ...

Tsunami
A tsunami ( ; from , ) 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 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 might give the false impression of ...

Paracel Chain
The Paracel Islands, also known as the Xisha Islands () and the Hoàng Sa Archipelago (), are a disputed archipelago in the South China Sea and currently controlled by the People's Republic of China. The word ''paracel'' is of Portuguese origin, meaning placer (a submerged bank or reef), and appears on 16th-century Portuguese maps. The archipelago includes about 130 small coral islands and reefs, most grouped into the northeastern Amphitrite Group or the western Crescent Group. They are distributed over a maritime area of around , with a land area of approximately . The archipelago is located about 220 miles (350 km) southeast of Hainan Island, equidistant from the coastlines of the People's Republic of China (PRC) and Vietnam, and approximately one-third of the way between central Vietnam and the northern Philippines. A feature of the Paracel Islands is Dragon Hole, the second deepest blue hole (underwater sinkhole) in the world. Sea turtles and seabirds are native to the ...

Dor, Israel
Dor () is a moshav in northern Israel. Located near Zikhron Ya'akov, it falls under the jurisdiction of Hof HaCarmel Regional Council. In it had a population of . Named after the ancient Phoenician city of Dor, the moshav was established in June 1948 on land of the recently depopulated Palestinian village of al-Tantura in the wake of the Tantura massacre. History Tel Dor The earliest remains at the Tel Dor site date back to the Canaanite period ending about 1200 BCE. Later, the Shkil tribe of sea raiders inhabited Tel Dor, as described in the letters of the Egyptian traveler Wen-Amon. The Phoenicians settled at Dor approximately 1100 BCE, and subsequently it became King Solomon's main port on the Mediterranean. Modern Dor was named after the ancient Phoenician city of Dor, which was inhabited by the tribe of Manasseh in the Israelite period. The city is mentioned in the Bible, in the Book of Joshua 17:11 and 1 Chronicles 7:29). The ancient city of Dor was situated on the ex ...

East Molokai Volcano
The East Molokai Volcano, sometimes also known as Wailau for the Wailau valley on its north side, is an extinct shield volcano comprising the eastern two-thirds of the island of Molokai in the U.S. state of Hawaii. Description The East Molokai has a width of and a length of . It is overlapped by the West Molokai, Lanai and Haleakalā shield volcanoes. Its shield formation began two million years ago and ended 1.5 million years ago whereas its postshield eruptions occurred 1.5 to 1.3 million years ago. The pahoehoe shield volcano of the Kalaupapa Peninsula postdates the main shield volcano of East Molokai and is considered to represent the last volcanic phase of East Molokai. East Molokai was one of the seven principal volcanoes, along with West Molokai, Lānai, West Maui, East Maui, Penguin Bank and Kahoolawe, that formerly constituted the island of Maui Nui. The highest point is the peak called Kamakou on the southern rim, at . The Pēpēōpae bog i ...

Molokai, Hawaii
Molokai or Molokai ( or ; Molokaʻi dialect: Morotaʻi ) is the fifth most populated of the eight major islands that make up the Hawaiian Islands archipelago in the middle of the Pacific Ocean. It is 38 by 10 miles (61 by 16 km) at its greatest length and width with a usable land area of , making it the fifth-largest in size of the main Hawaiian Islands and the 27th largest island in the United States. It lies southeast of Oʻahu across the wide Kaʻiwi Channel and north of Lānaʻi, separated from it by the Kalohi Channel. The island's agrarian economy has been driven primarily by cattle ranching, pineapple production, sugarcane production and small-scale farming. Tourism comprises a small fraction of the island's economy, and much of the infrastructure related to tourism was closed and barricaded in the early 2000s when the primary landowner, Molokai Ranch, ceased operations due to substantial revenue losses. In Kalawao County, on the Kalaupapa Peninsula on the north ...

Indigenous Peoples Of The Pacific Northwest Coast
The Indigenous peoples of the Americas, Indigenous peoples of the Pacific Northwest Coast are composed of many nations and tribal affiliations, each with distinctive cultural and political identities. They share certain beliefs, traditions and practices, such as the centrality of salmon as a resource and spiritual symbol, and many cultivation and subsistence practices. The term ''Northwest Coast'' or ''North West Coast'' is used in anthropology to refer to the groups of Indigenous people residing along the coast of what is now called British Columbia, Washington (state), Washington State, parts of Alaska, Oregon, and Northern California. The term ''Pacific Northwest'' is largely used in the American context. At one point, the region had the highest population density of a region inhabited by Indigenous peoples in Canada.Aboriginal Identity (8), Sex (3) and Age Groups (12) for the Population of Canada, Provinces, Territories, Census Metropolitan Areas and Census Agglomerations, 2006 ...

American Northwest
The Northwestern United States, also known as the American Northwest or simply the Northwest, is an informal geographic region of the United States. The region consistently includes the states of Oregon, Washington, Idaho, Montana and Wyoming. Some sources include Southeast Alaska in the Northwest. The related but distinct term Pacific Northwest generally excludes areas from the Rockies eastward, whereas the term "Inland Northwest" excludes areas west of the Cascades. The Northwestern United States is a subportion of the Western United States (which is, itself, even more ambiguous). In contrast, states included in the neighboring regions (Southwestern United States and Great Plains) and Utah are not simultaneously considered part of both regions. Like the southwestern United States, the Northwest definition has moved westward over time. The current area includes the old Oregon Territory (created in 1848–Oregon, Washington, Idaho, and areas in Montana west of the Continenta ...
