1896 Meiji-Sanriku Earthquake
The was one of the most destructive seismic events in Japanese history. The 8.5 Moment magnitude scale, 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 and tsunami, 2011 Tōhoku earthquake exceeded that height by more than . From the tsunami records the estimated Tsunami#Magnitude scales, 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 form ...

Sanriku Coast
The is a coastal region on the Pacific Ocean, extending from southern Aomori Prefecture, through Iwate Prefecture and northern Miyagi Prefecture in northeastern Honshū, which is Japan's main island. The name comes from the historical region of Sanriku (lit. "three ''riku''"), referring to the former provinces of Rikuō, Rikuchū and Rikuzen. Tourist destination There are the Tanesashi Coast, the Rikuchu Kaigan National Park and the Minami-Sanriku Kinkazan Quasi-National Park in the Sanriku Coast region. Earthquakes and tsunami The bays of this ria coastline tend to amplify the destructiveness of tsunami waves. Significant events which devastated coastal communities include: * 869 Jogan Sanriku earthquake * 1611 Keicho Sanriku earthquake * 1896 Meiji Sanriku earthquake * 1933 Showa Sanriku earthquake * 1960 Valdivia earthquake * 2011 Tōhoku earthquake and tsunami Prior to 2011, the tsunami history of Sanriku might have been interpreted as a story of progressively ...

Subduction
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate 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 the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1933 Sanriku Earthquake
The occurred on the Sanriku coast of the Tōhoku region of Honshū, Japan on March 2 with a moment magnitude of 8.4. The associated tsunami caused widespread devastation. Earthquake The epicenter was located offshore, east of the city of Kamaishi, Iwate. The main shock occurred at 02:31 AM local time on March 3, 1933 (17:31 UTC March 2, 1933) and measured 8.4 on the moment magnitude scale. It was in approximately the same location as the 1896 Sanriku earthquake and it occurred far enough away from the town that shaking did little damage. Approximately three hours after the main shock there was a magnitude 6.8 aftershock, followed by 76 more aftershocks (with a magnitude of 5.0 or greater) over a period of six months. This was an intraplate event that occurred within the Pacific Plate, and the focal mechanism showed normal faulting. Damage Although little damage was produced from the shock, the tsunami, which was recorded to reach the height of at Ōfunato, Iwate, ca ...

Japan Times
''The Japan Times'' is Japan's largest and oldest English-language daily newspaper. It is published by , a subsidiary of News2u Holdings, Inc.. It is headquartered in the in Kioicho, Chiyoda, Tokyo. History ''The Japan Times'' was launched by Motosada Zumoto on 22 March 1897, with the goal of giving Japanese people an opportunity to read and discuss news and current events in English to help Japan to participate in the international community. The newspaper was independent of government control, but from 1931 onward, the paper's editors experienced mounting pressure from the Japanese government to submit to its policies. In 1933, the Japanese Ministry of Foreign Affairs appointed Hitoshi Ashida, former ministry official, as chief editor. During World War II, the newspaper served as an outlet for Imperial Japanese government communication and editorial opinion. It was successively renamed ''The Japan Times and Mail'' (1918–1940) following its merger with ''The Japa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Sino-Japanese War
The First Sino-Japanese War (25 July 1894 – 17 April 1895) was a conflict between China and Japan primarily over influence in Korea. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the port of Weihaiwei, the Qing government sued for peace in February 1895. The war demonstrated the failure of the Qing dynasty's attempts to modernize its military and fend off threats to its sovereignty, especially when compared with Japan's successful Meiji Restoration. For the first time, regional dominance in East Asia shifted from China to Japan; the prestige of the Qing dynasty, along with the classical tradition in China, suffered a major blow. The humiliating loss of Korea as a tributary state sparked an unprecedented public outcry. Within China, the defeat was a catalyst for a series of political upheavals led by Sun Yat-sen and Kang Youwei, culminating in the 1911 Xinhai Revolution. The war is commonly known in China as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shinto
Shinto () is a religion from Japan. Classified as an East Asian religion by scholars of religion, its practitioners often regard it as Japan's indigenous religion and as a nature religion. Scholars sometimes call its practitioners ''Shintoists'', although adherents rarely use that term themselves. There is no central authority in control of Shinto, with much diversity of belief and practice evident among practitioners. A polytheistic and animistic religion, Shinto revolves around supernatural entities called the . The are believed to inhabit all things, including forces of nature and prominent landscape locations. The are worshiped at household shrines, family shrines, and ''jinja'' public shrines. The latter are staffed by priests, known as , who oversee offerings of food and drink to the specific enshrined at that location. This is done to cultivate harmony between humans and and to solicit the latter's blessing. Other common rituals include the dances, rites of ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological SurveyThe "USGS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accretionary Wedge
An accretionary wedge or accretionary prism forms from sediments accreted onto the non- subducting tectonic plate at a convergent plate boundary. Most of the material in the accretionary wedge consists of marine sediments scraped off from the downgoing slab of oceanic crust, but in some cases the wedge includes the erosional products of volcanic island arcs formed on the overriding plate. An accretionary complex is a current (in modern use) or former accretionary wedge. Accretionary complexes are typically made up of a mix of turbidites of terrestrial material, basalts from the ocean floor, and pelagic and hemipelagic sediments. For example, most of the geological basement of Japan is made up of accretionary complexes. Materials within an accretionary wedge Accretionary wedges and accreted terranes are not equivalent to tectonic plates, but rather are associated with tectonic plates and accrete as a result of tectonic collision. Materials incorporated in accretionary wedges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
