Wadati Benioff Zone
was an early seismologist at the Central Meteorological Observatory of Japan (now known as the Japan Meteorological Agency), researching deep (subduction zone) earthquakes. His name is attached to the Wadati–Benioff zone. It was Wadati's 1928 paper on shallow and deep earthquakes, comparing maximum below surface displacement against distance from the epicentre, which led Charles Richter to develop his earthquake magnitude scale in 1935.

Nagoya
is the largest city in the Chūbu region of Japan. It is the list of cities in Japan, fourth-most populous city in Japan, with a population of 2.3million in 2020, and the principal city of the Chūkyō metropolitan area, which is the List of metropolitan areas in Japan, third-most populous metropolitan area in Japan with a population of 10.11million. Located on the Pacific Ocean, Pacific coast in central Honshu, it is the capital and most populous city of Aichi Prefecture, with the Port of Nagoya being Japan's largest seaport. In 1610, the warlord Tokugawa Ieyasu, a retainer of Oda Nobunaga, moved the capital of Owari Province from Kiyosu to Nagoya. This period saw the renovation of Nagoya Castle. The arrival of the 20th century brought a convergence of economic factors that fueled rapid growth in Nagoya during the Meiji Restoration, and it became a major industrial hub for Japan. The traditional manufactures of timepieces, bicycles, and sewing machines were followed by the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Richter
Charles Francis Richter (; April 26, 1900September 30, 1985) was an American seismologist and physicist. He is the namesake and one of the creators of the Richter scale, which, until the development of the moment magnitude scale in 1979, was widely used to quantify the size of earthquakes. Inspired by Kiyoo Wadati's 1928 paper on shallow and deep earthquakes, Richter first used the scale in 1935 after developing it in collaboration with Beno Gutenberg; both worked at the California Institute of Technology. Childhood and education Richter was born in Overpeck, Ohio. Richter had German heritage: his great-grandfather was a Forty-Eighter, coming from Baden-Baden (today in Baden-Württemberg, Germany) in 1848 in the wake of the German revolutions of 1848–1849. Richter's parents Frederick William and Lillian Anna (Kinsinger) Richter, were divorced when he was very young. He grew up with his maternal grandfather, who moved the family (including his mother) to Los Angeles in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laureates Of The Imperial Prize
In English, the word laureate has come to signify eminence or association with literary awards or military glory. It is also used for recipients of the Nobel Prize, the Gandhi Peace Award, the Student Peace Prize, and for former music directors of orchestras who retain some level of involvement. History In ancient Greece, the laurel (''Laurus nobilis'') was sacred to Apollo, and as such, sprigs of it were fashioned into a crown or wreath of honor for poets and heroes. This symbolism has been widespread ever since. "Laureate letters" in old times meant the dispatches announcing a victory; and the epithet was given, even officially (e.g. to John Skelton) by universities, to distinguished poets. The name of "bacca-laureate" for a bachelor's degree shows a confusion with a supposed etymology from Latin bacca lauri (the laurel berry), which, though incorrect, involves the same idea. From the more general use of the term " poet laureate" arose its restriction in England to the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richter Magnitude Scale
The Richter scale (), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or .. Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses common logarithms simply to make the measurements man ...

Epicentre
The epicenter (), epicentre, or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Determination The primary purpose of a seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or magnitude must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of the earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture (focal mechanism). The first refinement that allowed a more precise determination of the location was the use of a time scale. Instead of merely noting, or recording, the absolute motions of a p ...
