Þingvallavatn
Þingvallavatn (, ), anglicised as Thingvallavatn, is a rift valley lake in southwestern Iceland. With a surface of 84 km2 it is the largest natural lake in Iceland. Its greatest depth is 114 m. At the northern shore of the lake, at Þingvellir (after which the lake is named), the Alþingi, the national parliament, was founded in the year 930, and held its sessions there until 1799 and still as of today the name Alþingi Íslendinga is carried by the parliament of Iceland. The lake lies partially within Þingvellir National Park. The volcanic origin of the islands in the lake is clearly visible. The cracks and faults around it, of which the Almannagjá ravine is the largest, is where the Eurasian and North American tectonic plates meet. Silfra fissure is a popular scuba and snorkeling site. The only outflow from lake Þingvallavatn is the river Sog. One of the noted features of the lake is the presence of four morphs of the Arctic charr.Malmquist, H. J., Snorrason, S. S. ...

2022 Þingvallavatn Plane Crash
2022 Þingvallavatn plane crash is an aviation accident which occurred on 3 February 2022 when a Cessna 172, Cessna 172N (TF-ABB) crash-landed into the partly-frozen lake of Þingvallavatn and sank during a sightseeing flight from Reykjavík Airport. All 4 people onboard died. Among those was Icelandic pilot Haraldur Diego, skateboarder and YouTuber Josh Neuman along with Nicola Bellavia and Tim Alings. The disappearance of the plane led to the biggest search and rescue operation for a missing plane in Iceland in over 40 years. The accident and rescue operations The 1977 Cessna 172N registered TF-ABB took off from Reykjavík Airport at 10:38 on the morning of 3 February 2022. The flight plan indicated a two-hour sightseeing flight. Footage from security cameras from summerhouses near Þingvallavatn showed the plane about an hour later doing what appeared to be an attempted landing or Touch-and-go landing, touch-and-go on the southern part of Þingvallavatn lake which was at the t ...

Silfra
Silfra () is a rift formed in the Mid-Atlantic Ridge – the divergent tectonic boundary between the North American and Eurasian plates – and is located in the Þingvallavatn Lake in the Þingvellir National Park in Iceland. Formation Silfra lies in the Þingvellir valley and within the Þingvellir National Park. The valley, and Silfra itself, were formed by the divergent tectonic drift of the Eurasian and North American plates. The plates drift about farther apart every year, building up tension between the plates and the earth mass above. This tension is relieved through periodic major earthquakes at approximately ten-year intervals, which have caused cracks and fissures to form in Þingvellir valley; Silfra lies at the rim of the Þingvallavatn Lake and is one of the largest and deepest of these fissures. The Silfra fissure intercepts a major aquifer, which feeds multiple springs at its base. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rift Valley
A rift valley is a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion. More generally the valley is likely to be filled with sedimentary deposits derived from the rift flanks and the surrounding areas. In many cases rift lakes are formed. One of the best known examples of this process is the East African Rift. On Earth, rifts can occur at all elevations, from the sea floor to plateaus and mountain ranges in continental crust or in oceanic crust. They are often associated with a number of adjoining subsidiary or co-extensive valleys, which are typically considered part of the principal rift valley geologically. Earth's rift valleys The most extensive rift valley is located along the crest of the mid-ocean ridge system and is the result ...

Arctic Charr
The Arctic char or Arctic charr (''Salvelinus alpinus'') is a cold-water fish in the family Salmonidae, native to alpine lakes, as well as Arctic and subarctic coastal waters in the Holarctic. Distribution and habitat It spawns in freshwater and its populations can be lacustrine, riverine, or anadromous, where they return from the ocean to their fresh water birth rivers to spawn. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen, which extends up to on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Great Britain and Ireland, found mainly in deep, cold, glacial lakes, and is at risk there from acidification. In other parts of its range, such as the Nordic countries, it is much more common, and is fished extensively. In Siberia, it is known as ''golets'' () and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the lon ...
