July 2008 Iwate Earthquake
The was an earthquake that occurred in Iwate Prefecture, Japan on July 23, 2008. The earthquake's moment magnitude was 6.8 and it occurred at a depth of 115 km. Since this earthquake was an intermediate-focus earthquake, the shaking of the earthquake was observed over a wide range. It had a maximum JMA intensity of ''Shindo'' 6− (Aomori and Iwate). Earthquake The earthquake ruptured a fault within the subducting Pacific Plate beneath northern Iwate at a calculated depth of . Earthquakes within the subducting slabs are intraslab events; other intraslab earthquakes including those occurring in 1987, 1993, 2001 and 2003 have been damaging. Although occurring deeper in Earth's interior, these events can produce large ground motions. In the case of this earthquake, the recorded peak ground acceleration exceeded 1,000 cm/sec2, corresponding to IX (''Violent'') on the Mercalli intensity scale. A seismic inversion study suggest the earthquake ruptured two fault segment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes Of The Heisei 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 ...

July 2008 Events In Japan
July is the seventh month of the year in the Julian and Gregorian calendars and is the fourth of seven months to have a length of 31 days. It was named by the Roman Senate in honour of Roman general Julius Caesar in 44 B.C., it being the month of his birth. Before then it was called Quintilis, being the fifth month of the calendar that started with March. It is on average the warmest month in most of the Northern Hemisphere, where it is the second month of summer, and the coldest month in much of the Southern Hemisphere, where it is the second month of winter. The second half of the year commences in July. In the Southern Hemisphere, July is the seasonal equivalent of January in the Northern hemisphere. "Dog days" are considered to begin in early July in the Northern Hemisphere, when the hot sultry weather of summer usually starts. Spring lambs born in late winter or early spring are usually sold before 1 July. July symbols *July's birthstone is the ruby, which symbol ...

USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency.

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.

内閣府
The (CAO) is an agency of the Cabinet of Japan. It is responsible for handling the day-to-day affairs of the Cabinet. The Cabinet Office is formally headed by the Prime Minister of Japan, Prime Minister. Ministers History The Cabinet Office was established on 6 January 2001, following the 2001 Central Government Reform, reorganization of the central government. It was created to assist in the planning and overall coordination of government policies led by the Cabinet (including the Cabinet Secretariat). The Cabinet Office is different from other ministries and agencies, as it is installed in the Cabinet and includes several Ministers of State called Minister of State for Special Missions. Early on, some argued it was inappropriate to use the name Cabinet Office because "it is an organization that divides and manages administrative affairs and not the cabinet itself". The National Administrative Organization Law does not apply, and all necessary items are stipulated in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seismic Inversion
In geophysics (primarily in oil-and-gas exploration/development), seismic inversion is the process of transforming seismic reflection data into a quantitative rock-property description of a reservoir. Seismic inversion may be pre- or post-stack, deterministic, random or geostatistical; it typically includes other reservoir measurements such as well logs and cores. Introduction Geophysicists routinely perform seismic surveys to gather information about the geology of an oil or gas field. These surveys record sound waves which have traveled through the layers of rock and fluid in the earth. The amplitude and frequency of these waves can be estimated so that any side-lobe and tuning effects introduced by the wavelet may be removed. Seismic data may be inspected and interpreted on its own without inversion, but this does not provide the most detailed view of the subsurface and can be misleading under certain conditions. Because of its efficiency and quality, most oil and gas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
