Land Subsidence
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement. Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock. Ground subsidence is of global concern to geologists, geotechnical engineers, surveyors, engineers, urban planners, landowners, and the public in general.National Research Council, 1991.

Kofun Period
The is an era in the history of Japan from about 300 to 538 AD (the date of the introduction of Buddhism), following the Yayoi period. The Kofun and the subsequent Asuka periods are sometimes collectively called the Yamato period. This period is the earliest era of recorded history in Japan, but studies depend heavily on archaeology since the chronology of historical sources tends to be distorted. The word '' kofun'' is Japanese for the type of burial mound dating from this era. It was a period of cultural import. Continuing from the Yayoi period, the Kofun period is characterized by influence from China and the Korean Peninsula; archaeologists consider it a shared culture across the southern Korean Peninsula, Kyūshū and Honshū. On the other hand, the most prosperous keyhole-shaped burial mounds in Japan during this period were approximately 5,000 in Japan from the middle of the 3rd century in the Yayoi period to the 7th century in the Asuka period, and many of them had huge t ...

Kofun
are megalithic tombs or tumuli in Northeast Asia. ''Kofun'' were mainly constructed in the Japanese archipelago between the middle of the 3rd century to the early 7th century CE.岡田裕之「前方後円墳」『日本古代史大辞典』大和書房、2006年。 The term is the origin of the name of the Kofun period, which indicates the middle 3rd century to early–middle 6th century. Many ''kofun'' have distinctive keyhole-shaped mounds (). The Mozu- Furuichi kofungun or tumulus clusters were inscribed on the UNESCO World Heritage List in 2019, while Ishibutai Kofun is one of a number in Asuka-Fujiwara residing on the Tentative List. Overview The ''kofun tumuli'' have assumed various shapes throughout history. The most common type of ''kofun'' is known as a , which is shaped like a keyhole, having one square end and one circular end, when viewed from above.

Yayoi Period
The started at the beginning of the Neolithic in Japan, continued through the Bronze Age, and towards its end crossed into the Iron Age. Since the 1980s, scholars have argued that a period previously classified as a transition from the Jōmon period should be reclassified as Early Yayoi. The date of the beginning of this transition is controversial, with estimates ranging from the 10th to the 3rd centuries BC. The period is named after the Yayoi, Tokyo, neighbourhood of Tokyo where Archaeology, archaeologists first uncovered artifacts and features from that era in the late 19th century. Distinguishing characteristics of the Yayoi period include the appearance of new Yayoi pottery styles and the start of an intensive rice agriculture in paddy fields. A hierarchical social class structure dates from this period and has its origin in China. Techniques in metallurgy based on the use of bronze and iron were also introduced from China via Korea to Japan in this period. The Yayoi foll ...

Jōmon Period
The is the time in Japanese history, traditionally dated between 6,000–300 BCE, during which Japan was inhabited by a diverse hunter-gatherer and early agriculturalist population united through a common Jōmon culture, which reached a considerable degree of sedentism and cultural complexity. The name "cord-marked" was first applied by the American zoologist and orientalist Edward S. Morse, who discovered sherds of pottery in 1877 and subsequently translated it into Japanese as ''Jōmon''.Mason, 14 The pottery style characteristic of the first phases of Jōmon culture was decorated by impressing cords into the surface of wet clay and is generally accepted to be among the oldest in the world. The Jōmon period was rich in tools and jewelry made from bone, stone, shell and antler; pottery figurines and vessels; and lacquerware.Imamura, K.

Midden
A midden (also kitchen midden or shell heap) is an old dump for domestic waste which may consist of animal bone, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
