Emergency Warning System
Emergency Warning System () is a warning system the Japan Meteorological Agency (JMA) launched on 30 August 2013. Emergency Warnings are issued to alert people to the significant likelihood of catastrophes in association with natural phenomena of extraordinary magnitude. Residents should take all measures possible to protect themselves in the event that an Emergency Warning is issued. Overview JMA issues various warnings to alert people to possible catastrophes caused by extraordinary natural phenomena such as heavy rain, earthquakes, tsunami and storm surges. In addition to such warnings, advisories and other bulletins, JMA started issuing Emergency Warnings to alert people to the significant likelihood of catastrophes if phenomena are expected to be of a scale that will far exceed the warning criteria. Emergency Warnings are intended for extraordinary phenomena such as the major tsunami caused by the 2011 Great East Japan Earthquake by which 18,000 people were killed or left ...

Natural Phenomena
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ise Bay
is a bay located at the mouth of the Kiso Three Rivers between Mie and Aichi Prefectures in Japan. Ise Bay has an average depth of and a maximum depth of . The mouth of the bay is and is connected to the smaller Mikawa Bay by two channels: the Nakayama Channel and the Morosaki Channel. Mikawa Bay is subsequently joined to the Pacific Ocean by the Irako Channel, which ranges from in depth. History and environment Ise Bay derives its name from the region surrounding Ise Grand Shrine and the city of Ise, where the shrine stands. The flat coastal plain that stretches from Kuwana in northern Mie Prefecture to Ise is called the Ise Plain and this plain lies on the western shore of Ise Bay. Prior to the Meiji Period, Ise Province consisted of most of modern Mie Prefecture. From ancient times, Ise Bay has provided the people of the surrounding regions with a rich abundance of natural resources as well as providing easy transport. As a result, unique communities developed around the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Vera
Typhoon Vera, also known as the , was an exceptionally intense tropical cyclone that struck Japan in September 1959, becoming the strongest and deadliest typhoon on record to make landfall on the country as a Category 5 equivalent storm. The storm's intensity resulted in catastrophic damage of unparalleled severity and extent, and was a major setback to the Japanese economy, which was still recovering from World War II. In the aftermath of Vera, Japan's disaster management and relief systems were significantly reformed, and the typhoon's effects would set a benchmark for future storms striking the country. Vera developed on September 20 between Guam and Chuuk State, and initially tracked westward before taking a more northerly course, reaching tropical storm strength the following day. By this point Vera had assumed a more westerly direction of movement and had begun to rapidly intensify, and reached its peak intensity on September 23 with maximum sustained winds ...

Tropical Storm Talas (2011)
Severe Tropical Storm Talas (formerly called Typhoon Talas), was an unusually large tropical cyclone that caused many deaths and severe damage to Japan. It was the 12th named storm and the 7th severe tropical storm of the 2011 Pacific typhoon season. Talas is known to have killed at least 82 people, and 16 more are still missing. The word ''Talas'' is a Filipino word meaning ''sharpness''. It followed five months after Japan was hit by a large tsunami. Throughout Japan, Talas brought heavy rainfall leaving roads flooded. Extremely heavy rainfall of 66.5 millimeters per hour was observed, with rainfall of 69.0 mm in Yamanakako, Yamanashi, and 49.5 mm in Ichinoseki, Iwate which exceeded overall records for the entire month of September. Some 3,200 people were evacuated in 16 prefectures after extremely heavy rain. Some 700 houses were completely inundated by floods in eastern and western Japan and about 9,500 households in nine prefectures across the nation suffered powe ...

Tsunami Warning (Japan)
Japan has a nationwide Tsunami Warning system (). The system usually issues warnings a few minutes after an Earthquake Early Warning (Japan), Earthquake Early Warning (EEW) is issued, should waves be expected, usually when a combination of high magnitude, seaward epicenter and vertical focal mechanism is observed. The tsunami warning was issued within 3 minutes with the most serious rating on its warning scale during the 2011 Tōhoku earthquake and tsunami; it was rated as a "major tsunami", being at least 3 m (9.8 ft) high. An improved system was unveiled on March 7, 2013, following the 2011 disaster to better assess imminent tsunamis. Overview When an earthquake occurs, the Japan Meteorological Agency (JMA) estimates the possibility of tsunami generation from seismic observation data. If disastrous waves are expected in coastal regions, JMA issues a Tsunami Warning/Advisory for each region expected to be affected based on estimated tsunami heights. JMA also issues info ...

Volcanic Warning
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic ...

Earthquake Early Warning (Japan)
In Japan, the is a warning issued when an earthquake is detected by multiple seismometers. These warnings are primarily issued by the Japan Meteorological Agency (JMA), with guidance on how to react to them. Intro The JMA has two EEW systems: one for the general public and another for the National Meteorological and Hydrological Services. When a P-wave is detected from two (or more) of the 4,235 seismometers installed throughout Japan, the JMA analyzes and predicts the approximate location of the earthquake's epicenter. This allows the JMA to notify people in affected prefectures by TV and radio if a strong earthquake is expected. An Earthquake Early Warning is issued to warn the general public when an earthquake of 5 or higher on the Japan seismic scale is expected. An EEW forecast (緊急地震速報(予報)) is issued to the National Meteorological and Hydrological Services when an earthquake of 3 or higher on the Japan seismic scale (or 3.5 or higher on the Richter magnit ...

Warning Systems
Warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it. Warnings cannot be effective unless people react to them. People are more likely to ignore a system that regularly produces false warnings (the cry-wolf effect), but reducing the number of false warnings generally also increases the risk of not giving a warning when it is needed. Some warnings are non-specific: for instance, the probability of an earthquake of a certain magnitude in a certain area over the next decade. Such warnings cannot be used to guide short-term precautions such as evacuation. Opportunities to take long-term precautions, such as better building codes and disaster preparedness, may be ignored.
