Garth Tsunami
The Garth tsunami is a likely prehistoric tsunami off the Shetland Islands that may have occurred 5,500 years ago (3,500 BCE). Its origin is unknown; impact events, earthquakes, and submarine landslides similar to the Storegga Slide 8,100 years ago (6,100 BCE) have been proposed as factors contributing to the event. Evidence suggests a run-up of more than in the Shetland Islands. It probably had great impact on coastal communities in the region; mass burials dating approximately to that time in the Shetland and Orkney Islands have been interpreted to host its fatalities. Name, chronology and size The tsunami is named after Garth Loch. It likely took place approximately 5,500 years ago and also is known as the "5,500 BP event". It generated a run-up of more than in the Shetland Islands. This tsunami is one of three thought to have hit Scotland during the Holocene although the occurrence of this of a later one are considered uncertain. Deposits Deposits from the tsunami hav ...

Prehistoric
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orkney Islands
Orkney (; sco, Orkney; on, Orkneyjar; nrn, Orknøjar), also known as the Orkney Islands, is an archipelago in the Northern Isles of Scotland, situated off the north coast of the island of Great Britain. Orkney is 10 miles (16 km) north of the coast of Caithness and has about 70 islands, of which 20 are inhabited. The largest island, the Mainland, has an area of , making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. Orkney’s largest settlement, and also its administrative centre, is Kirkwall. Orkney is one of the 32 council areas of Scotland, as well as a constituency of the Scottish Parliament, a lieutenancy area, and an historic county. The local council is Orkney Islands Council, one of only three councils in Scotland with a majority of elected members who are independents. The islands have been inhabited for at least years, originally occupied by Mesolithic and Neolithic tribes and then by the Picts. Orkney was col ...

Overwash
Overwash is the flow of water and sediment over a coastal dune or beach crest during storm events (or other situations with high water). 'Overwash' may refer only to the landward flux of water due to overtopping of a dune system while 'washover' may refer to the sediment deposited by overwash. A common process on barrier islands, Overwash redistributes sediment and facilitates the migration of barrier islands in response to sea level rise. Overwash can occur as a result of runup (the maximum height of the swash), or inundation. Deposition from overwash (washover) can be deposited onto the beach berm, the dune, or as far as the back barrier bay, marsh, estuary, or lagoon. Sediment deposits created during overwash exhibit consistent scaling — for example, the distance inland that an overwash deposit extends is proportional to the area that the overwash deposit covers. The distance inland that an overwash deposit extends is also correlated with the volume of sand deposited. The amou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamre, Osterøy
Hamre is a village in the municipality of Osterøy in Vestland county, Norway. The village of Hamre is located near the extreme western point on the island of Osterøy, across the Osterfjorden from the village of Knarvik. Hamre sits about north of the village of Valestrandfossen. The village has a population (2019) of 210 and a population density of . Hamre village was the administrative centre of the former municipality of Hamre, which existed from 1838 until 1964.

Stone Age
The Stone Age was a broad prehistoric period during which stone was widely used to make tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years, and ended between 4,000 BC and 2,000 BC, with the advent of metalworking. Though some simple metalworking of malleable metals, particularly the use of gold and copper for purposes of ornamentation, was known in the Stone Age, it is the melting and smelting of copper that marks the end of the Stone Age. In Western Asia, this occurred by about 3,000 BC, when bronze became widespread. The term Bronze Age is used to describe the period that followed the Stone Age, as well as to describe cultures that had developed techniques and technologies for working copper alloys (bronze: originally copper and arsenic, later copper and tin) into tools, supplanting stone in many uses. Stone Age artifacts that have been discovered include tools used by modern humans, by their predecessor species in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Grave
A mass grave is a grave containing multiple human corpses, which may or may not be identified prior to burial. The United Nations has defined a criminal mass grave as a burial site containing three or more victims of execution, although an exact definition is not unanimously agreed upon. Mass graves are usually created after many people die or are killed, and there is a desire to bury the corpses quickly for sanitation concerns. Although mass graves can be used during major conflicts such as war and crime, in modern times they may be used after a famine, epidemic, or natural disaster. In disasters, mass graves are used for infection and disease control. In such cases, there is often a breakdown of the social infrastructure that would enable proper identification and disposal of individual bodies. History Mass or communal burial was a common practice before the development of a dependable crematory chamber by Ludovico Brunetti in 1873. In ancient Rome waste and dead bodies of the ...

2004 Indian Ocean Earthquake And Tsunami
An earthquake and a tsunami, known as the Boxing Day Tsunami and, by the scientific community, the Sumatra–Andaman earthquake, occurred at 07:58:53 local time (UTC+7) on 26 December 2004, with an epicentre off the west coast of northern Sumatra, Indonesia. It was an undersea megathrust earthquake that registered a magnitude of 9.1–9.3 , reaching a Mercalli intensity up to IX in certain areas. The earthquake was caused by a rupture along the fault between the Burma Plate and the Indian Plate. A series of massive tsunami waves grew up to high once heading inland, after being created by the underwater seismic activity offshore. Communities along the surrounding coasts of the Indian Ocean were devastated, and the tsunamis killed an estimated 227,898 people in 14 countries, making it one of the deadliest natural disasters in recorded history. The direct results caused major disruptions to living conditions and commerce in coastal provinces of surrounded countries, including Ac ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Chambered Cairn
A chambered cairn is a burial monument, usually constructed during the Neolithic, consisting of a sizeable (usually stone) chamber around and over which a cairn of stones was constructed. Some chambered cairns are also passage-graves. They are found throughout Britain and Ireland, with the largest number in Scotland. Typically, the chamber is larger than a cist, and will contain a larger number of interments, which are either excarnated bones or inhumations (cremations). Most were situated near a settlement, and served as that community's "graveyard". Scotland Background During the early Neolithic (4000–3300 BC) architectural forms are highly regionalised with timber and earth monuments predominating in the east and stone-chambered cairns in the west. During the later Neolithic (3300–2500 BC) massive circular enclosures and the use of grooved ware and Unstan ware pottery emerge. Scotland has a particularly large number of chambered cairns; they are found in various differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faroe–Shetland Channel
The Faroe–Shetland Channel is stretch of the North Atlantic lying between the two island groups of Shetland and the Faroe Islands. The channel is a rift basin that separates the Scottish and the Faroese continental shelves, and has a maximum depth of 1900 m, compared to the surrounding seabed which mostly lies at 200 m. It was first noted by Charles Wyville Thomson during the mid-nineteenth century. Strategically, the channel forms part of the GIUK gap. Nature and conservation Since 2014 two parts of the channel lying with Scottish Offshore Waters have been designated as Nature Conservation Marine Protected Areas: *The Faroe-Shetland Sponge Belt MPA covers in an region of sea where the mixing of relatively warmer North Atlantic water with sub-zero deep water from the Norwegian Sea leads to a diverse range of sea life in the area, including fields of slow-growing deep-sea sponges that are a key feature of the MPA designation.

Meteorite Impact
An impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Major impact events have significantly shaped Earth's history, and have been implicated in the formation of the Earth–Moon system. Impact events also appear to have played a significant role in the evolutionary history ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
