European-Mediterranean Seismological Centre
The European-Mediterranean Seismological Centre (EMSC; french: Centre Sismologique Euro-Méditerranéen, ) is an international, non-governmental and not-for-profit organisation. The European-Mediterranean region is prone to destructive earthquakes. When an earthquake occurs, a scientific organisation is needed to determine, as quickly as possible, the characteristics of the seismic event. The European-Mediterranean Seismological Centre (EMSC) receives seismological data from more than 65 national seismological agencies, mostly in the Euro-Mediterranean region. The most relevant earthquake parameters, such as the earthquake location and the earthquake magnitude, and the shaking felt by the population are available within one hour from the earthquake onset. History The European-Mediterranean Seismological Centre (EMSC) is a not-for-profit organisation with 84 member institutes from 55 different countries. The centre was established in 1975 under the request of the European Seism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquake And Seismic Risk Mitigation
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 ...

Focal Mechanism
The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault-related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can be derived from observing the pattern of "first motions", that is, whether the first arriving P waves break up or down. This method was used before waveforms were recorded and analysed digitally and this method is still used for earthquakes too small for easy moment tensor solution. Focal mechanisms are now mainly derived using semi-automatic analysis of the recorded waveforms. Moment tensor solutions The moment tensor solution is typically displayed graphically using a so-called ''beachball'' diagram. The pattern o ...

Framework Programmes For Research And Technological Development
The Framework Programmes for Research and Technological Development, also called Framework Programmes or abbreviated FP1 to FP9, are funding programmes created by the European Union/European Commission to support and foster research in the European Research Area (ERA). Starting in 2014, the funding programmes were named Horizon. The funding programmes began in 1984 and continue to the present day. The most recent programme, Horizon Europe, has a budget of 95.5 billion Euros to be distributed over 7 years. The specific objectives and actions vary between funding periods. In FP6 and FP7, focus was on technological research. In Horizon 2020, the focus was on innovation, delivering economic growth faster, and delivering solutions to end users that are often governmental agencies. Background Conducting European research policies and implementing European research programmes is an obligation under the Amsterdam Treaty, which includes a chapter on research and technological development ...

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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Council Of Europe
The Council of Europe (CoE; french: Conseil de l'Europe, ) is an international organisation founded in the wake of World War II to uphold human rights, democracy and the rule of law in Europe. Founded in 1949, it has 46 member states, with a population of approximately 675 million; it operates with an annual budget of approximately 500 million euros. The organisation is distinct from the European Union (EU), although it is sometimes confused with it, partly because the EU has adopted the original European flag, created for the Council of Europe in 1955, as well as the European anthem. No country has ever joined the EU without first belonging to the Council of Europe. The Council of Europe is an official United Nations Observer. Being an international organization, the Council of Europe cannot make laws, but it does have the ability to push for the enforcement of select international agreements reached by member states on various topics. The best-known body of the Council of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institut De Physique Du Globe De Strasbourg
An institute is an organisational body created for a certain purpose. They are often research organisations (research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute" (see Institute of Technology). In some countries, such as South Korea and India, private schools are sometimes referred to as institutes, and in Spain, secondary schools are referred to as institutes. Historically, in some countries institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from a Latin word ''institutum'' meaning "facility" or "habit"; from ''instituere'' meaning "build", "create", "raise" or "educate". ...

Earthquake Magnitude
Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's seismic waves as recorded on a seismogram. Magnitude scales vary on what aspect of the seismic waves are measured and how they are measured. Different magnitude scales are necessary because of differences in earthquakes, the information available, and the purposes for which the magnitudes are used. Earthquake magnitude and ground-shaking intensity The Earth's crust is stressed by tectonic forces. When this stress becomes great enough to rupture the crust, or to overcome the friction that prevents one block of crust from slipping past another, energy is released, some of it in the form of various kinds of seismic waves that cause ground-shaking, o ...

Earthquake Location
The primary purpose of a seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or Moment magnitude scale must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of the earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture (focal mechanism). The first refinement that allowed a more precise determination of the location, was the use of a time scale. Instead of merely noting, or recording, the absolute motions of a pendulum, the displacements were plotted on a moving graph, driven by a clock mechanism. This was the first seismogram, which allowed precise timing of the first ground motion, and an accurate plot of sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
