1026 Manju Tsunami
The 1026 Manju tsunami affected the Sea of Japan coast of then Iwami Province on June 16. Considered one of the largest tsunamis in the Sea of Japan, it generated a tsunami with waves of at present-day Masuda, Shimane. Off the coast, an island reportedly sunk because of the waves. More than 1,000 people were killed and 3,000 homes were destroyed. The source of the tsunami has been debated between an earthquake or undersea landslide. Description In historical records, locals claimed that a large stone called ''Kuroiwa'' was carried by the tsunami to its present location in Tonda, Masuda, Tonda, along Japan National Route 9 about from Masuda Station. The tall stone was allegedly carried from the coast at an elevation of . A subsequent investigation revealed the stone, comprising basalt, originated from the inland mountains, as basalts do not occur at the coast, and was transported downhill by a landslide rather than the reported tsunami. The tsunami reportedly sunk the island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwami Province
was an old province of Japan in the area that is today the western part of Shimane Prefecture. It was sometimes called . Iwami bordered Aki, Bingo, Izumo, Nagato, and Suō provinces. In the Heian period (794–1192) the capital was at modern-day Hamada. In the Kamakura period (1192–1333) the Masuda clan belonged to the Minamoto clan ( Genji) and conquered Iwami Province. From the sixteenth century onwards, it played an important role in East Asia's economic history as a major silver source. History During the Muromachi and Sengoku periods, the battles were very furious in this area. At first, the Masuda clan was in alliance with the Ōuchi clan in neighboring Suō, but later the Masuda clan belonged to the Mōri clan in neighboring Aki. On 16 June 1026, a tsunami struck the Sea of Japan coast of present-day Masuda, Shimane, killing more than 1,000 people. Maps of Japan and Iwami Province were reformed in the 1870s when the prefecture system was introduced. At the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsunami Deposit
A tsunami deposit (the term tsunamiite is also sometimes used) is a sedimentary unit deposited as the result of a tsunami. Such deposits may be left onshore during the inundation phase or offshore during the 'backwash' phase. Such deposits are used to identify past tsunami events and thereby better constrain estimates of both earthquake and tsunami hazards. There remain considerable problems, however, in distinguishing between deposits caused by tsunamis and those caused by storms or other sedimentary processes. Tsunamiite The term "tsunamiite" or "tsunamite" was introduced in the 1980s to describe deposits interpreted to have been formed by traction processes associated with tsunamis and is particularly used for marine deposits formed during the "backwash" phase. The term's application has broadened to encompass all tsunami-related deposits, but its use has been challenged. The main criticism of the term is that it describes deposits that have formed by many different processes th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1020s In Japan
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11th-century Disasters
The 11th century is the period from 1001 (represented by the Roman numerals MI) through 1100 (MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium. In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy. In Song dynasty China and the classical Islamic world, this century marked the high point for both classical Chinese civilization, science and technology, and classical Islamic science, philosophy, technology and literature. Rival political factions at the Song dynasty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Shimane Prefecture
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...

Earthquakes In Japan
This is a list of earthquakes in Japan with either a magnitude greater than or equal to 7.0 or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter scale (''ML'') or the moment magnitude scale (''Mw''), or the surface-wave magnitude, surface wave magnitude scale (''Ms'') for very old earthquakes. The present list is not exhaustive, and furthermore reliable and precise magnitude data is scarce for earthquakes that occurred before the development of modern measuring instruments. History Although there is mention of an earthquake in Yamato Province, Yamato in what is now Nara Prefecture on August 23, 416, the first earthquake to be reliably documented took place in Nara prefecture on May 28, 599 during the reign of Empress Suiko, destroying buildings throughout Yamato province.Hammer, Joshua.

Tsunamis In Japan
A tsunami ( ; from , ) 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 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 the false impression of a ca ...

List Of Tsunamis
This article lists notable tsunamis, which are sorted by the date and location that they occurred. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, but are a worldwide natural phenomenon. They are possible wherever large bodies of water are found, including inland lakes, where they can be caused by landslides and glacier calving. Very small tsunamis, non-destructive and undetectable without specialized equipment, occur frequently as a result of minor earthquakes and other events. Around 1600 BC, the eruption of Thira devastated Aegean sites including Akrotiri (prehistoric city). Some Minoan sites in eastern Crete may have been damaged by ensuing tsunamis. The oldest recorded tsunami occurred in 479 BC. It destroyed a Persian army that was attacking the town of Potidaea in Greece.Smid, T.

Undersea Landslide
Submarine landslides are marine landslides that transport sediment across the continental shelf and into the deep ocean. A submarine landslide is initiated when the downwards driving stress (gravity and other factors) exceeds the resisting stress of the seafloor slope material, causing movements along one or more concave to planar rupture surfaces. Submarine landslides take place in a variety of different settings, including planes as low as 1°, and can cause significant damage to both life and property. Recent advances have been made in understanding the nature and processes of submarine landslides through the use of sidescan sonar and other seafloor mapping technology. Causes Submarine landslides have different causes which relate to both the geological attributes of the landslide material and transient environmental factors affecting the submarine environment. Common causes of landslides include: i) presence of weak geological layers, ii) overpressure due to rapid accumulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, 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 Atmosphere of Earth, 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.
