Hanauma Bay
Hanauma (; ) is a marine embayment formed within a tuff ring and located along the southeast coast of the Island of Oahu in the Hawaii Kai neighborhood of East Honolulu, in the Hawaiian Islands. Hanauma is one of the most popular tourist destinations on the Island and has suffered somewhat from overtourism. At one time, this popular tourist destination accommodated over three million visitors per year. In 1956, dynamite was used to clear portions of the reef to make room for telephone cables linking Hawaii to the west coast of the US. Name The prefix ''hana'' means bay in the Hawaiian language (the usual addition of bay in its name is thus redundant). There are two etymological interpretations of the second part of its name. One interpretation derives it from the Hawaiian word for curve, referring to either the shape of the feature or to the shape of the indigenous canoes that were launched there. Another stems from the indigenous hand-wrestling game known as "Uma". Marine lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uma (game)
A folk wrestling style is any traditional style of wrestling, which may or may not be codified as a modern sport. Most cultures have developed regional forms of grappling. Europe Britain Traditionally wrestling has two main centres in Great Britain: the West Country, where the Devon and Cornwall styles were developed, and in the Northern counties; the home of the Cumberland and Westmorland styles and Catch wrestling. North Country styles * Lancashire wrestling is a historic wrestling style from Lancashire in England known for its "Catch-as-catch-can", or ''no wrestling holds barred'', style. ** Catch wrestling, or Catch-as-catch-can, originated from Lancashire wrestling but was further developed during the travelling circus phenomenon of the 19th and early 20th century. * Backhold Wrestling, whose origin is unknown, was practised in North England and Scotland in the 7th and 8th century but competitions are held in present-day at the Highland and Border Games as well as in Fr ...

French Frigate Shoals
The French Frigate Shoals ( Hawaiian: Kānemilohai) is the largest atoll in the Northwestern Hawaiian Islands. Its name commemorates French explorer Jean-François de La Pérouse, who nearly lost two frigates when attempting to navigate the shoals. It consists of a crescent-shaped reef, twelve sandbars, and the La Perouse Pinnacle, the only remnant of its volcanic origins. The total land area of the islets is . Total coral reef area of the shoals is over . Tern Island, with an area of , has a landing strip and permanent habitations for a small number of people. It is maintained as a field station in the Hawaiian Islands National Wildlife Refuge by the United States Fish and Wildlife Service. The French Frigate Shoals are about northwest of Honolulu. In the 20th century, the shoals were used by the Imperial Japanese Navy as part of an operation to attack Hawaii; afterwards, a small United States Navy base was established there to prevent it from being used again.

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Honolulu Volcanic Series
The Honolulu Volcanics are a group of volcanoes which form a volcanic field on the island of Oʻahu, Hawaiʻi, more specifically in that island's southeastern sector and in the city of Honolulu from Pearl Harbor to the Mokapu Peninsula. It is part of the rejuvenated stage of Hawaiian volcanic activity, which occurred after the main stage of volcanic activity that on Oʻahu built the Koʻolau volcano. These volcanoes formed through dominantly explosive eruptions and gave rise to cinder cones, lava flows, tuff cones and volcanic islands. Among these are well known landmarks such as Diamond Head and Punchbowl Crater. Volcanic activity began less than one million years ago and occurred at between 40 and 30 separate volcanic vents, some of which are submarine. Sea level varied during the activity of the volcanic field, and some volcanic eruptions have been dated through correlation with individual sea level fluctuations. The field erupted various kinds of lavas of mostly basalti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tectonic Plate
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or ''transform''. Earthquakes, volcanic activity, mountain-building, and oceanic tren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...
