National Geophysical Data Center
The United States National Geophysical Data Center (NGDC) provided scientific stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. It was established in 1965 as part of the new Environmental Science Services Administration until that organization became the National Oceanic & Atmospheric Administration (NOAA) in 1970. In 2015, NGDC was merged with the National Climatic Data Center (NCDC) and the National Oceanographic Data Center (NODC) into the National Centers for Environmental Information (NCEI). Location and controlling bodies Since 1972 the NGDC was located in Boulder, Colorado as a part of the US Department of Commerce (USDOC), National Oceanic & Atmospheric Administration (NOAA), National Environmental Satellite, Data and Information Service (NESDIS). Data holdings NGDC's data holdings contained more than 300 digital and analog databases, with over 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
æ°è±¡åº
The Japan Meteorological Agency (JMA; ''æ°è±¡åº, KishÅ-chÅ'') is a division of the Ministry of Land, Infrastructure, Transport and Tourism dedicated to the scientific observation and research of natural phenomena. Headquartered in Minato, Tokyo the agency collects data on meteorology, hydrology, seismology, volcanology, and other related fields. The JMA is responsible for collecting and disseminating weather data and forecasts to the public, as well as providing specialized information for aviation and marine sectors. Additionally, the JMA issues warnings for volcanic eruptions and is integral to the nationwide Earthquake Early Warning (EEW) system. As one of the Regional Specialized Meteorological Centers designated by the World Meteorological Organization (WMO), the JMA also forecasts, names, and distributes warnings for tropical cyclones in the Northwestern Pacific region. This includes areas such as the Celebes Sea, the Sulu Sea, the South China Sea, the East Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Standard Time
, or , is the standard time zone in Japan, 9 hours ahead of UTC (UTC+09:00). Japan does not observe daylight saving time, though its introduction has been debated on several occasions. During World War II, the time zone was often referred to as Tokyo Standard Time. Japan Standard Time is equivalent to Time in South Korea, Korean Standard Time, Time in North Korea, Pyongyang Time (North Korea), Time in Indonesia, Eastern Indonesia Standard Time, Time in East Timor, East-Timorese Standard Time, Time in Palau, Palau Time, and Yakutsk Time (Russia). History Before the Meiji (era), Meiji era (1868â1912), each local region had its own time zone in which noon was when the sun was exactly at its culmination. As modern transportation methods, such as trains, were adopted, this practice became a source of confusion. For example, there is a difference of about 5 degrees longitude between Tokyo and Osaka and because of this, a train that departed from Tokyo would arrive at Osaka 20 minu ...

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak 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. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moment Magnitude
The moment magnitude scale (MMS; denoted explicitly with or Mwg, 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. 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 use the term "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 saturatethat 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 United States Geological SurveyTh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Earthquakes In 1968
This is a list of earthquakes in 1968. 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. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. There was a large resurgence in activity in 1968. 22 magnitude 7.0+ earthquakes struck various parts of the planet. The largest of these was a magnitude 8.2 event in Japan in May. Large aftershocks struck the area following the mainshock. New Zealand and Indonesia had some upheaval during the year. The high activity contributed to over 12,000 deaths across the world. The vast majority of this total was caused by a destructive event in Iran in August with nearly 10,500 deaths. Events in the Phil ...

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 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.
