Sayama Pond
is an artificial reservoir located in the city of Ōsakasayama, Osaka Prefecture in the Kansai region of Japan. Constructed around the 6th century, it claims to be the oldest in Japan, based on chronological survey of potteries near the lake confirmed that the pond was completed in 7th century. The pond was designated a National Historic Site in 1946, and is listed as World Heritage Irrigation Structure by ''International Commission of Irrigation and Drainage''. Overview The origins of the Sayama Pond are not clear; it was completed some time between the fourth and seventh centuries, during the Kofun to Asuka period. It appears in both the "Kojiki" and " Nihon Shoki", which states that it was made during the reign of Emperor Sujin by damming the north-flowing Nishiyoke and Mitsuya rivers. It is believed to have been repaired by Gyōki in 731, and again in 762 after a collapse of the embankment. Further repairs were recorded in 1202 and in 1608. During the Edo Period, the pond w ...

Archaeological Excavation
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years. Excavation involves the recovery of several types of data from a site. This data includes artifacts (portable objects made or modified by humans), features (non-portable modifications to the site itself such as post molds, burials, and hearths), ecofacts (evidence of human activity through organic remains such as animal bones, pollen, or charcoal), and archaeological context (relationships among the other types of data).Kelly&Thomas (2011). ''Archaeology: down to earth'' (4th ed.). Belmont, Calif.: Wadsworth, Cengage Learning. Before excavating, the presence or absence of archaeological remains can often be suggested by, non-intrusive remote sensing, such as ground-penetrating radar. Basic informat ...

1605 Keichō Earthquake
The 1605 Keichō earthquake () occurred at about 20:00 local time on 3 February. It had an estimated magnitude of 7.9 on the surface wave magnitude scale and triggered a devastating tsunami that resulted in thousands of deaths in the Nankai and Tōkai regions of Japan. It is uncertain whether there were two separate earthquakes separated by a short time interval or a single event. It is referred to as a tsunami earthquake, in that the size of the tsunami greatly exceeds that expected from the magnitude of the earthquake. Background The southern coast of Honshu runs parallel to the Nankai Trough, which marks the subduction of the Philippine Sea Plate beneath the Eurasian Plate. Movement on this convergent plate boundary leads to many earthquakes, some of them of megathrust type. The Nankai megathrust has five distinct segments (A-E) that can rupture independently, the segments have ruptured either singly or together repeatedly over the last 1,300 years. Megathrust earthquakes on ...

684 Hakuhō Earthquake
The 684 Hakuho earthquake took place in Japan in 684, and is described in the history book '' Nihon Shoki'' from the 8th century. The earthquake took place on 29 November, 684, in 13th year of the reign of Emperor Tenmu (Tenmu period). It caused the under-sea inundation of approximately of rice fields. A number of great interplate earthquakes have occurred along the Suruga Trough and Nankai Trough, off the southwestern coasts of Japan. These earthquakes are associated with the subduction of the Philippine Sea Plate. These recurring earthquakes take place at intervals of one or two centuries. These earthquakes take place in pairs, with an example of Tōkai earthquakes taking place in eastern Japan, and an example of Nankai earthquakes taking place in western Japan. The Hakuho earthquake is the oldest recorded Nankai earthquake. The earthquake is associated with strong ground motion, and damaged a broad area. It affected the capital city of Asuka, and caused a tsunami. There was subs ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) 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 other 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 ...

Diatoms
A diatom (New Latin, Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's Biomass (ecology), biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Dep ...
