1952 Hokkaido Earthquake
The 1952 Tokachi earthquake (), occurred at on 4 March in the sea near Tokachi District, Hokkaidō, Japan. It had a magnitude of 8.1 on the moment magnitude scale. Damage There was earthquake and tsunami damage in an area ranging from Hokkaido to the northern part of the Tohoku region. As a result, 28 people were killed, five were missing, and 287 were wounded. In addition, 815 houses were completely destroyed, 1324 half-damaged, and 6395 partially damaged. Ninety-one houses were swept away, 328 suffered flooding, 20 were lost to fire, and 1621 became uninhabitable. Furthermore, 451 ships were damaged. In Hamanaka, in the Akkeshi District, Hokkaidō, a tsunami destroyed numerous homes. It is thought that drift ice was pushed up by the tsunami and exacerbated the damage. Eight years later, this area was devastated by the tsunami caused by the 1960 Chile earthquake, killing 11 people. Akkeshi Bay saw the highest tsunami surge, of , with Hachinohe in Aomori also seeing a wave. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tsunami Warning System
A tsunami warning system (TWS) is used to detect tsunamis in advance and issue the warnings to prevent loss of life and damage to property. It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas. There are two distinct types of tsunami warning systems: international and regional. When operating, seismic alerts are used to instigate the watches and warnings; then, data from observed sea level height (either shore-based tide gauges or DART buoys) are used to verify the existence of a tsunami. Other systems have been proposed to augment the warning procedures; for example, it has been suggested that the duration and frequency content of t-wave energy (which is earthquake energy trapped in the ocean SOFAR channel) is indicative of an earthquake's tsunami potential. History and forecasting The first rudimentary system to alert communities of an im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Hokkaido
is Japan, Japan's Japanese archipelago, second largest island and comprises the largest and northernmost Prefectures of Japan, prefecture, making up its own List of regions of Japan, region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only Cities designated by government ordinance of Japan, ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are Kuril Islands dispute, claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''.Louis Frédéric, Nussbaum, Louis-Frédéric. (2005).

1952 Earthquakes
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

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 zone ...

Earthquakes Of The Showa Period
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes ca ...

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.

List Of Earthquakes In 1952
This is a list of earthquakes in 1952. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Two events dominated 1952 in seismic terms. Firstly in March a magnitude 8.1 earthquake struck Japan resulting in a robust aftershock sequence. Then in November, a magnitude 9.0 earthquake rocked the Kamchatka area of Russia. This event was the largest and deadliest of the year. The Kamchatka quake was not only the largest of 1952, but also one of the largest of all time. Overall By death toll * Note: At least 10 casualties By magnitude * Note: At least 7.0 magnitude Notable events January February March April May June July August September October ...

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, caused ex ...
