869 Jōgan Earthquake
The and its associated tsunami struck the area around Sendai in the northern part of Honshu on 9 July 869 (the 26th day of the 5th month in the 11th year of Jōgan; or 13 July 869). The earthquake had an estimated magnitude of at least 8.6 on the moment magnitude scale, but may have been as high as 9.0, similar to the 2011 Tōhoku earthquake and tsunami. The tsunami caused widespread flooding of the Sendai plain. In 2001, researchers identified sand deposits in a trench more than from the coast as coming from this tsunami. Name In Japan this earthquake is commonly called . Jōgan is the Japanese era name for the period from 859 to 877 AD. But during the era other large earthquakes also occurred in Japan, so the name of the geographic epicenter and the anno domini year number when the quake occurred are sometimes added. Sanriku in this context is a name roughly corresponding to the Pacific front northeastern coastal area of Honshu island. The Japanese history text, '' Nihon Sa ...

Emishi
The were a group of people who lived in parts of northern Honshū in present-day Japan, especially in the Tōhoku region. The first mention of the Emishi in literature that can be corroborated with outside sources dates to the 5th century AD, in which they are referred to as (毛人—"hairy people") in Chinese records. Some Emishi tribes resisted the rule of various Japanese emperors during the Asuka, Nara, and early Heian periods (7th–10th centuries AD). The origin of the Emishi is disputed and continues to be a topic of discussion; however, some theories propose a connection to either the Epi-Jōmon tribes of Japan which became the ancestors of the Ainu people of Hokkaido, or pre-Yamato Japanese migrants. It has been posited that the Emishi may have either spoken a unique Japonic language similar to the Izumo dialect, or a distinct language related to Ainu, or both. Moreover, even though there is a significant geographical gap between Northeast Japan and the South� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tōhoku Region
The , Northeast region, , or consists of the northeastern portion of Honshu, the largest island of Japan. This traditional region consists of six prefectures (): Akita, Aomori, Fukushima, Iwate, Miyagi, and Yamagata. Tōhoku retains a reputation as a remote, scenic region with a harsh climate. In the 20th century, tourism became a major industry in the Tōhoku region. History Ancient and classical period In mythological times, the area was known as Azuma (, ) and corresponded to the area of Honshu occupied by the native Emishi and Ainu. The area was historically the Dewa and the Michinoku regions, a term first recorded in (654). There is some variation in modern usage of the term "Michinoku". Tōhoku's initial historical settlement occurred between the seventh and ninth centuries, well after Japanese civilization and culture had become firmly established in central and southwestern Japan.

Indigenous Peoples
There is no generally accepted definition of Indigenous peoples, although in the 21st century the focus has been on self-identification, cultural difference from other groups in a state, a special relationship with their traditional territory, and an experience of subjugation and discrimination under a dominant cultural model. Estimates of the population of Indigenous peoples range from 250 million to 600 million. There are some 5,000 distinct Indigenous peoples spread across every inhabited climate zone and inhabited continent of the world. Most Indigenous peoples are in a minority in the state or traditional territory they inhabit and have experienced domination by other groups, especially non-Indigenous peoples. Although many Indigenous peoples have experienced colonization by settlers from European nations, Indigenous identity is not determined by Western colonization. The rights of Indigenous peoples are outlined in national legislation, treaties and international law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1896 Sanriku Earthquake
The was one of the most destructive seismic events in Japanese history. The 8.5 magnitude earthquake occurred at 19:32 (local time) on June 15, 1896, approximately off the coast of Iwate Prefecture, Honshu. It resulted in two tsunami waves which destroyed about 9,000 homes and caused at least 22,000 deaths. The waves reached a then-record height of ; this would remain the highest on record until waves from the 2011 Tōhoku earthquake exceeded that height by more than . From the tsunami records the estimated tsunami's magnitude is (Mt = 8.2), much greater than expected for the seismic magnitude estimated from the observed seismic intensity (=7.2). This earthquake is now regarded as being part of a distinct class of seismic events, the tsunami earthquake. Geology The epicenter lies just to the west of the Japan Trench, the surface expression of the west-dipping subduction zone. The trench forms part of the convergent boundary between the Pacific and Eurasian plates. Magnitu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subduction
Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at the convergent boundaries between tectonic plates. Where one tectonic plate converges with a second plate, the heavier plate dives beneath the other and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with rates of convergence as high as 11 cm/year. Subduction is possible because the cold and rigid oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle. Once initiated, stable subduction is driven mostly by the negative buoyancy of the dense subducting lithosphere. The down-going slab sinks into the mantle largely under its own ...
