1854 Tōkai Earthquake
The 1854 Tōkai earthquake was the first of the Ansei great earthquakes (1854–1855). It occurred at about 09:00 local time on 23 December 1854. It had a magnitude of 8.4 and caused a damaging tsunami. More than 10,000 buildings were destroyed and there were at least 2,000 casualties. It was the first of the three Ansei great earthquakes; the 1854 Ansei-Nankai earthquake of similar size hit southern Honshu the following day. Background The southern coast of Honshu runs parallel to the Nankai Trough, which marks the subduction of the Philippine Sea Plate beneath the Eurasian Plate. Movement on this convergent plate boundary leads to many earthquakes, some of them of megathrust type. The Nankai megathrust has five distinct segments (A-E) that can rupture independently, the segments have ruptured either singly or together repeatedly over the last 1300 years. Megathrust earthquakes on this structure tend to occur in pairs, with a relatively short time gap between them. In additio ...

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 Francis Richter and presented in his 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 logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Megathrust Earthquakes In Japan
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (''Mw'') that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. The thrust faults responsible for megathrust earthquakes often lie at the bottom of oceanic trenches; in such cases, the earthquakes can abruptly displace the sea floor over a large area. As a result, megathrust earthquakes often generate tsunamis that are considerably more destructive than the earthquakes themselves. Teletsunamis can cross ocean basins to devastate areas far from the original earthquake. Terminology and mechanism The term ''megathrust'' refers to an extremely large thrust fault, typically formed at the plate interface along a subduction zo ...

List Of Historical Tsunamis
This article lists notable tsunamis, which are sorted by the date and location that the tsunami 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, a tsunami caused by the eruption of Thira devastated the Minoan civilization on Crete and related cultures in the Cyclades, as well as in areas on the Greek mainland facing the eruption, such as the Argolid. The oldest recorded tsunami occurred in 479 BC. It destroyed a Persian army that was attacking the town of Potidaea in Greece.Smid, T. C.: "' ...

List Of Historical Earthquakes
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the beginning of the 20th century. As the events listed here occurred before routine instrumental recordings, they rely mainly on the analysis of written sources. There is often significant uncertainty in location and magnitude and sometimes date for each earthquake. The number of fatalities is also often highly uncertain, particularly for the older events. Pre-11th century 11th–18th centuries 19th century Source for all events with 'USGS' labelled as the source United States Geological Survey (USGS''Note: Magnitudes are generally estimations from intensity data.

List Of 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 magnitude scale (''ML'') or the moment magnitude scale (''Mw''), or the 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 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.

Suruga Bay
Suruga Bay (駿河湾, ''Suruga-wan'') is a bay on the Pacific coast of Honshū in Shizuoka Prefecture, Japan. It is situated north of a straight line from Omaezaki Point to Irōzaki Point at the tip of the Izu Peninsula and surrounded by Honshū to the southwest and west and the Izu Peninsula to the east. Geology Suruga Bay is a place of contrasts. Japan's loftiest peak, Mount Fuji at , rises from the depth of the Suruga Trough running up the middle of the bay, which makes it Japan's deepest. Numerous rivers—especially the major Fuji, the Ōi, and Abe rivers—empty into its western portion, giving that area of the bay a seabed rich in submarine canyons and other geographical features, whereas at the bay's easternmost end, only the Kano River empties into a pocket called Uchiura-wan at Numazu, Shizuoka, where the Izu Peninsula connects to Honshu, giving the water greater transparency and leaving the seabed largely flat except for a number of small rocky islands, some j ...

Treaty Of Shimoda
The Treaty of Shimoda (下田条約, ''Shimoda Jouyaku'') (formally Treaty of Commerce and Navigation between Japan and Russia 日露和親条約, ''Nichi-Ro Washin Jouyaku'') of February 7, 1855, was the first treaty between the Russian Empire, and the Empire of Japan, then under the administration of the Tokugawa shogunate. Following shortly after the Convention of Kanagawa signed between Japan and the United States, it effectively meant the end of Japan's 220-year-old policy of national seclusion (''sakoku''), by opening the ports of Nagasaki, Shimoda and Hakodate to Russian vessels and established the position of Russian consuls in Japan and defined the borders between Japan and Russia. The isolation of Japan Since the beginning of the seventeenth century, the Tokugawa shogunate pursued a policy of isolating the country from outside influences. Foreign trade was maintained only with the Dutch and the Chinese and was conducted exclusively at Nagasaki under a strict governmen ...

Yevfimy Putyatin
Yevfimiy Vasilyevich Putyatin (russian: Евфи́мий Васи́льевич Путя́тин; November 8, 1803 – October 16, 1883), also known as was an admiral in the Imperial Russian Navy. His diplomatic mission to Japan resulted in the signing of the Treaty of Shimoda in 1855, for which he was made a count. His mission to China in 1858 resulted in the Russian Treaty of Tianjin. Early life Putyatin was descended from a noble family in Novgorod. He entered the Naval Cadet Corps, graduating in 1822, and soon afterwards was appointed to the crew of Mikhail Petrovich Lazarev which circumnavigated the globe in a three-year voyage from 1822 to 1825. He subsequently participated in the Battle of Navarino during the Greek War of Independence on October 20, 1827 and was awarded the Order of St. Vladimir, 4th degree. From 1828 to 1832, the participated in numerous missions in the Mediterranean and in the Baltic, and was awarded the Order of St George, 4th class. ...

Diana (Russian Ship)
''Diana'' was a frigate of the Imperial Russian Navy. She was built in 1853, and was the flagship of the Russian explorer Yevfimy Putyatin when he visited Japan in 1854 to negotiate what would become the Treaty of Shimoda. Putyatin's fleet was damaged in a tsunami, following the powerful Ansei-Tōkai earthquake of 23 December 1854. ''Diana'' was spun round 42 times on its moorings and was so badly damaged that it sank in a later storm in the bay of Miyajima-mura (宮島村) (modern Fuji-shi, 富士市), while sailing from Shimoda to Heda for repairs. Three hundred Japanese carpenters worked with the Russian sailors to build a Western-style ship in two months, with the help of plans salvaged from ''Diana''. They eventually built a two-masted schooner A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant ...

Shimoda, Shizuoka
270px, Shimoda City Hall is a city and port located in Shizuoka Prefecture, Japan. , the city had an estimated population of 21,402 in 10,787 households, and a population density of 200 persons per km2. The total area of the city is . In the 1850s, Japan was in political crisis over its increasing inability to maintain its national seclusion policy and the issue of what relations, if any, it should have with foreign powers. For a few years, Shimoda was central to this debate. Geography Shimoda is located at the southern tip of the Izu Peninsula about 100 kilometres southwest of Tokyo. Shimoda's location, with the Amagi Mountains to the north, and the warm Kuroshio Current to the south give the city a humid, sub-tropical climate. Surrounding Municipalities *Shizuoka Prefecture ** Minamiizu ** Kawazu ** Matsuzaki Demographics Per Japanese census data, the population of Shimoda has been in slow decline over the past 40 years.
