ʻAilāʻau Eruption
The ʻAilāʻau eruption is a prehistoric eruption of Kīlauea volcano on the island of Hawaiʻi in the Hawaiian Islands. Carbon 14 dated from approximately 1410 to 1470 with an eruptive volume of 5.2 ± 0.8 km3 and fed by lava tubes near Kīlauea Iki crater, it was among the last of a series of highly voluminous lava flows since about 1290 that blanketed vast swaths of what is now Hawaii County's Puna District. The Kazumura Cave lava tubes were also created by this eruption. The ʻAilāʻau eruption occurred before written records, but was witnessed by Ancient Hawaiians, and through their oral traditions it is thought to have inspired the Hawaiian myth of ʻAilāʻau, whose name in the Hawaiian language Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed.

Kīlauea
Kīlauea ( , ) is an active shield volcano in the Hawaiian Islands. Located along the southeastern shore of the Big Island of Hawaii, the volcano is between 210,000 and 280,000 years old and emerged above sea level about 100,000 years ago. Historically, it is the most active of the five volcanoes that together form Hawaii island. Kīlauea is also one of the most active volcanoes on Earth, and the most recent and currently ongoing eruption began on September 29, 2021, when several vents began to erupt lava within Halemaʻumaʻu, a pit crater in the volcano's summit caldera. Kīlauea is the second-youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa, Kīlauea was once thought to be a satellite of its much larger neighbor. Structurally, Kīlauea has a large, fairly recently formed caldera at its summit and two ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii County, Hawaii
Hawaii County ( haw, Kalana o Hawaiʻi) (officially known as the County of Hawaii) is a county in the U.S. state of Hawaii in the Hawaiian Islands. It is coextensive with the Island of Hawaii, often called the "Big Island" to distinguish it from the state as a whole. The 2020 Census population was 200,629. The county seat is Hilo. There are no incorporated cities in Hawaii County (see Hawaii Counties). The Hilo Micropolitan Statistical Area includes all of Hawaii County. Hawaii County has a mayor–council form of government. Hawaii County is the largest county in the state in terms of geography. The mayor of Hawaii County is Mitch Roth, who took office in 2020. Legislative authority is vested in a nine-member Hawaii County Council. Hawaii County is one of seven counties in the United States to share the same name as the state they are in (the other six are Arkansas County, Idaho County, Iowa County, New York County, Oklahoma County, and Utah County, Utah, Utah County). ...

15th-century Volcanic Events
The 15th century was the century which spans the Julian dates from 1 January 1401 ( MCDI) to 31 December 1500 ( MD). In Europe, the 15th century includes parts of the Late Middle Ages, the Early Renaissance, and the early modern period. Many technological, social and cultural developments of the 15th century can in retrospect be seen as heralding the "European miracle" of the following centuries. The architectural perspective, and the modern fields which are known today as banking and accounting were founded in Italy. The Hundred Years' War ended with a decisive French victory over the English in the Battle of Castillon. Financial troubles in England following the conflict resulted in the Wars of the Roses, a series of dynastic wars for the throne of England. The conflicts ended with the defeat of Richard III by Henry VII at the Battle of Bosworth Field, establishing the Tudor dynasty in the later part of the century.

Hawaiian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-langua ...

Hawaiian Mythology
Hawaiian religion refers to the indigenous religious beliefs and practices of native Hawaiians, also known as the kapu system. Hawaiian religion is based largely on the tapu religion common in Polynesia and likely originated among the Tahitians and other Pacific islanders who landed in Hawaii between 500 and 1300 AD. It is polytheistic and animistic, with a belief in many deities and spirits, including the belief that spirits are found in non-human beings and objects such as other animals, the waves, and the sky. It was only during the reign of Kamehameha I that a ruler from Hawaii island attempted to impose a singular "Hawaiian" religion on all the Hawaiian islands that was not Christianity. Today, Hawaiian religious practices are protected by the American Indian Religious Freedom Act. Traditional Hawaiian religion is unrelated to the modern New Age practice known as " Huna".Rothstein, Mikael, in Lewis, James R. and Daren Kemp. ''Handbook of New Age''. Brill Academic Publisher ...

Ancient Hawaii
Ancient Hawaii is the period of Hawaiian history preceding the unification in 1810 of the Kingdom of Hawaii by Kamehameha the Great. Traditionally, researchers estimated the first settlement of the Hawaiian islands as having occurred sporadically between 400 and 1100 CE by Polynesian long-distance navigators from the Samoan, Marquesas, and Tahiti islands within what is now French Polynesia. In 2010, a study was published based on radiocarbon dating of more reliable samples which suggests that the islands were settled much later, within a short timeframe, in about 1219 to 1266. The islands in Eastern Polynesia have been characterized by the continuities among their cultures, and the short migration period would be an explanation of this result. Diversified agroforestry and aquaculture provided sustenance for Native Hawaiian cuisine. Tropical materials were adopted for housing. Elaborate temples (called ''heiau'') were constructed from the lava rocks available. The rich natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kazumura Cave
Kazumura Cave is a lava tube and has been surveyed at 40.7 miles (65.5 km) long and 3,614 feet (1,102 m) deep making it the longest and deepest lava tube in the world. The cave is located on the island of Hawaiʻi on the eastern slope of Kīlauea. Kīlauea is the most recently active volcano on the Big Island. The ʻAilāʻau lava flow that contains Kazumura Cave originated from the Kīlauea Iki Crater about 500 years ago. History One of the earliest documentations of Kazumura Cave was in 1966 when one of its entrances was designated as a fallout shelter. By the early 1970s, the cave had entered into the awareness of the caving community when Francis Howarth discovered new troglobitic moth species, '' Schrankia howarthi''. Later in 1981, a British expedition ended up surveying 7.27 miles (11.7 km) of the cave and it was then recognized as one of the world's longest lava tubes. By 1993, a single year of extensive surveying established that it was the longest in the world. Or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
