European Alert System
The European Alert System (sometimes referred to as the European Alarm System or European Warning System) is an earthquake warning system for member states of the Council of Europe's EUR-OPA Major Hazards Agreement. Seismic alerts are provided by the European-Mediterranean Seismological Centre (EMSC), an international, non-governmental, and non-profit association based at the Laboratoire de Détection et de Géophysique (LDG) of the French Atomic Energy Commission (Commissariat à l'Energie Atomique - CEA) in Bruyères-le-Châtel (Essonne, France). Until 1993, the EMSC was based in Strasbourg. Competence and notification The EMSC's main area of competence is the following: *west: to the mid-Atlantic ridge, north of 30°N *north : to the Arctic ocean *east: to the Urals and the regions bordering the Caspian Sea and the Black Sea *south : to the regions bordering the Mediterranean Sea. The competent region also includes, as far as possible, territories of member states of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquake Warning System
An earthquake warning system or earthquake early warning system is a system of accelerometers, seismometers, communication, computers, and alarms that is devised for notifying adjoining regions of a substantial earthquake while it is in progress. This is not the same as earthquake prediction, which is currently incapable of producing decisive event warnings. Time lag and wave projection An earthquake is caused by the release of stored elastic strain energy during rapid sliding along a fault. The sliding starts at some location and progresses away from the hypocenter in each direction along the fault surface. The speed of the progression of this fault tear is slower than, and distinct from the speed of the resultant pressure and shear waves, with the pressure wave traveling faster than the shear wave. The pressure waves generate an abrupt shock. The shear waves generate periodic motion (at about 1 Hz) that is the most destructive to structures, particularly buildings that ...

EU-Alert
EU-Alert is the generic term for the European Public Warning Service based upon Cell Broadcast technology. EU-Alert is compatible with Wireless Emergency Alerts (WEA) formerly known as the Commercial Mobile Alert System (CMAS) standard as used in the United States. Since 2012, and by default, mobile phone OSes like Android, iOS, and Windows support EU-Alert/WEA/CMAS via Cell Broadcast for public warning messages. EU-Alert standard The EU-Alert standard (TS 102 900 V1.3.1) as defined by ETSI is the European Public Warning Service using the Cell Broadcast Service as a means of delivering public warning messages to the general public. Specific countries using the EU-Alert service are identified by replacing the letters EU with the Country Identification letters in ISO 3166-1 : * NL-Alert: The national variant of EU-Alert for the Netherlands. * GR-Alert: The national variant of EU-Alert for Greece. * LT-Alert: The national variant of EU-Alert for Lithuania. RO-Alert The national ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Management
Emergency management or disaster management is the managerial function charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies, which can be understood as minor events with limited impacts and are managed through the day to day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also common.

Earthquake Prediction
Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, and particularly "the determination of parameters for the ''next'' strong earthquake to occur in a region". Earthquake prediction is sometimes distinguished from ''earthquake forecasting'', which can be defined as the probabilistic assessment of ''general'' earthquake hazard, including the frequency and magnitude of damaging earthquakes in a given area over years or decades. Not all scientists distinguish "prediction" and "forecast", but the distinction is useful. Prediction can be further distinguished from earthquake warning systems, which upon detection of an earthquake, provide a real-time warning of seconds to neighboring regions that might be affected. In the 1970s, scientists were optimistic that a practical method for predicting earthquakes would soon be found, but by the 1990s continuing failur ...

Kamchatka Peninsula
The Kamchatka Peninsula (russian: полуостров Камчатка, Poluostrov Kamchatka, ) is a peninsula in the Russian Far East, with an area of about . The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and the Karaginsky Island, constitute the Kamchatka Krai of the Russian Federation. The vast majority of the 322,079 inhabitants are ethnic Russians, although about 13,000 are Koryaks (2014). More than half of the population lives in Petropavlovsk-Kamchatsky (179,526 in 2010) and nearby Yelizovo (38,980). The Kamchatka peninsula contains the volcanoes of Kamchatka, a UNESCO World Heritage Site. Geography Politically, the peninsula forms part of Kamchatka Krai. The southern tip is called Cape Lopatka. (Lopatka is Russian for spade.) The circular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Office For The Coordination Of Humanitarian Affairs
The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) is a United Nations (UN) body established in December 1991 by the General Assembly to strengthen the international response to complex emergencies and natural disasters. It is the successor to the Office of the United Nations Disaster Relief Coordinator (UNDRO). The Department of Humanitarian Affairs (DHA) was established shortly thereafter by the Secretary-General, but in 1998 was merged into OCHA, which became the UN's main focal point on major disasters. OCHA's mandate was subsequently broadened to include coordinating humanitarian response, policy development and humanitarian advocacy. Its activities include organizing and monitoring humanitarian funding, advocacy, policy-making, and information exchange to facilitate rapid-response teams for emergency relief. OCHA is led by the Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator (USG/ERC), appointed for a five-year ...

European Commission
The European Commission (EC) is the executive of the European Union (EU). It operates as a cabinet government, with 27 members of the Commission (informally known as "Commissioners") headed by a President. It includes an administrative body of about 32,000 European civil servants. The Commission is divided into departments known as Directorates-General (DGs) that can be likened to departments or ministries each headed by a Director-General who is responsible to a Commissioner. There is one member per member state, but members are bound by their oath of office to represent the general interest of the EU as a whole rather than their home state. The Commission President (currently Ursula von der Leyen) is proposed by the European Council (the 27 heads of state/governments) and elected by the European Parliament. The Council of the European Union then nominates the other members of the Commission in agreement with the nominated President, and the 27 members as a team are ...
