    Descriptive info: PROJECT DESCRIPTION.. Earthquakes are a serious threat for many countries of Europe, particularly for those around the Mediterranean Sea.. Early warning systems, based on the real time, automated analysis of ground-motion measurements, can play an important role in reducing the negative impact of such catastrophic events on densely populated areas and in mitigating the damage to strategic structures and lifelines.. Europe is covered by numerous high quality seismic networks, managed by national and international agencies, including local networks specifically designed for seismic early warning around large cities such as Bucharest, Istanbul and Naples.. The SAFER project aims to fully exploit the possibilities offered by the real-time analysis of  ...   of minutes.. These actions range from the shutting down of critical systems of lifelines, industries, highways, railways, etc.. , the activation of control systems for the protection of crucial structures, the supplying of information to support decision making for the rapid response of emergency management services (e.. g.. ground shaking maps, continuously updated damage scenario estimates, aftershocks hazard etc.. ).. The project is structured into 6.. work-packages.. , that address all major components of an earthquake early warning system:.. Project Coordination and Management.. Real-Time Estimation of Source Parameters.. Real-Time Damage Assessment and Reduction Strategies.. Real- Time Shake Maps.. Real-Time Aftershock Hazard Assessment..

    Descriptive info: OBJECTIVES.. The primary aim of SAFER is to develop tools that can be used by disaster management authorities for effective earthquake early warning in Europe and, in particular, the densely populated cities.. The tools are expected to be user-friendly, have the maximum possible portability, and to be in accordance with state-of-the-art research.. In particular, SAFER will be concerned with the following:.. The development of improved algorithms for the rapid determination of earthquake source parameters (real-time event detection and location, real-time fault mapping, as well as new approaches for fast magnitude/moment determination based on strong motion data and modern seismic array technology).. Further elaboration of new concepts, including the virtual seismologist, for providing, in an evolutionary process, real-time alert maps and predicted shake maps within seconds and minutes, as well as measured shake maps within a few minutes.. Development of fast algorithms for damage scenario simulations and the improvement  ...   Napoli and Cairo).. To reach these objective, a strategic approach has been developed that addressed all major components of the earthquake early warning chain, as outlined in the various project work-packages.. It starts with real-time hazard assessment (WP2, WP4) immediately from the first detection of a strong earthquake, includes components of vulnerability assessment (WP3), real-time risk assessment (WP3) and real-time risk reduction.. (WP3) within a few seconds before the first damage may occur, and also deals with the new aspect of real-time aftershock hazard assessment (WP5).. Strengthening the interface of these scientific-technological components with the decision-making and response component (WP6) is especially emphasized.. The work-package numbers shown in the brackets above do not indicate the entire activity fields in each of the work-packages, but represent their major focus, respectively.. The Earthquake Early Warning Chain.. Considered Test Areas in the Project.. (large circles: prototype cities, small circles: additional test areas)..

Source Date December 5, 2006 More on Earthquakes, Natural Disasters, Tsunamis, Construction, Wildfires, Earth Science Powerful Earthquakes Can Be Detected Within Two Seconds Could a few seconds warning of an impending strong earthquake be of practical use in mitigating its effects? Scientists, engineers, and first responders say yes, and now such warnings may be possible.. Researchers in Italy have analyzed seismic signals from over 200 moderate to strong earthquakes, ranging from magnitude 4.. 0 to 7.. 4, and they conclude that the waves generated in the first few seconds of an earthquake (the primary, or P, waves) carry sufficient information to determine its magnitude and destructive potential.. Aldo Zollo and Maria Lancieri of the University of Naples and Stefan Nielsen of the National Institute of Geophysics and Vulcanology in Rome determined that the peak amplitudes of very early seismic signals recorded in the vicinity of an earthquake source correlate with the earthquake magnitude and may be used for real-time estimation of the size of the event.. Surprisingly, the researchers say, earthquake magnitude can be estimated using just two seconds' worth of signal from the first recorded P and S (secondary) waves, that is, while the earthquake is still in progress and far from over.. The study will be published later this month in Geophysical Research Letters.. Primary waves travel around six kilometers [four miles] per second, covering around 60 kilometers [40 miles] in 10 seconds.. Secondary, or S, waves, which are usually more destructive, travel more slowly, around 3.. 5 kilometers [2.. 2 miles] per second, covering only around 17 kilometers [11 miles] in 10 seconds.. Therefore, a city located around 60 kilometers [40 miles] from an epicenter would have around 15 seconds of lead time to prepare for an earthquake's impact, the time difference between the arrival of the first P wave at a recording station near the epicenter and the arrival of the S wave at the city itself.. In the study, the researchers looked into the entire active seismic belt of the Mediterranean region, which includes varying geological and tectonic systems and faults.. They compared signals from both P and S waves from more than 200 earthquakes and found that stress release and/or slip duration on the fault in the very early stage of seismic fracture relates both to the observed peak amplitude of the early P wave and to the elastic energy available for propagation of the fracture.. Although relatively few magnitude 7 earthquakes have hit the study area in recent years, there have been many instances of quakes in the magnitude 6 range.. (A magnitude 7 earthquake is over 30 times more energetic than one of magnitude 6.. ) Zollo notes that even magnitude 6 quakes can produce great damage, especially in urbanized areas and places where old structures were not built to current standards; this defines much of the Mediterranean basin and applies also in other areas.. The researchers say that installations as close as 50 kilometers [30 miles] from the epicenter could receive an earthquake warning 10 seconds prior to the arrival of the main body wave of an earthquake.. Places further from the epicenter would have additional time, though still measured in seconds.. To take advantage of this brief warning period, automated systems would have to be created that respond instantly to notification alert signals, and they would have to be carefully calibrated to avoid missed or false alarms.. Engineers note that in tall buildings, the higher floors sway much more than those near ground level, so that even a moderate earthquake could cause severe damage to a highrise, Zollo says.. Therefore, even at 70-80 kilometers [40-50 miles] distance from its epicenter, a magnitude 6 quake could affect hospital operating rooms and other critical installations.. Closer to the epicenter, a magnitude 6 or higher earthquake can damage critical infrastructure, such as telephone lines, gas pipelines, highways, and railroads, as well as airport runways and navigation systems.. These disruptions would have a domino effect in more distant areas, which could be mitigated by an early warning alert system, based on the earliest primary wave data to arrive at recording stations close to the epicenter.. The researchers note that earthquake early warning systems can also help mitigate the effects of such earthquake-induced disasters as fires, explosions, landslides, and tsunamis, which can in many cases be more devastating than the earthquake itself.. Systems could be installed at relatively low cost in developing countries, where moderate sized earthquakes can cause damage comparable to that caused by much larger earthquakes in developed countries, they say.. The study was funded in part by the consortium Analisi e Monitoraggio del Rischi Ambientali (AMRA) scarl through the European Union-Seismic Early Warning for Europe (EU-SAFER) project.. Conocen grado destructivo de sismo.. El Dictamen.. Madrid / EFE.. El poder destructivo de un terremoto puede conocerse sólo dos segundos después de que se haya registrado, según una investigación europea que ha estudiado 200 terremotos de entre 4 y 7,4 grados de magnitud en la escala Ritcher.. El trabajo, que publicará el próximo número de la revista 'Geophysical Research Letters', concluye que las ondas generadas en los primeros segundos de un terremoto (ondas primarias o P) contienen suficiente información como para determinar su magnitud y su potencial destructivo.. Los investigadores Aldo Zollo y María Lancieri, de la Universidad de Nápoles (Italia), y Stefan Nielsen, del Instituto Nacional de Geofísica y Vulcanología de Roma, han determinado los picos de amplitud de las primeras señales sísmicas recogidas en el entorno del epicentro de un terremoto y su correlación con la magnitud que acaba alcanzando.. Tras estudiar 200 terremotos sucedidos en los últimos años en todo el Mediterráneo, una zona de gran variedad geológica y tectónica, concluyen que la magnitud de un terremoto podría estimarse utilizando sólo las señales recogidas durante los primeros segundos del seísmo.. Las ondas primarias (P) viajan a una velocidad de 6 kilómetros por segundo, y, por lo tanto, son capaces de llegar a 60 kilómetros del epicentro en 10 segundos..

Los investigadores Aldo Zollo y María Lancieri, de la Universidad de Nápoles (Italia), y Stefan Nielsen, del Instituto Nacional de Geofísica y Vulcanología de Roma, han determinado los picos de amplitud de las primeras señales sísmicas recogidas en el entorno del epicentro de un terremoto y su correlación con la magnitud que acaba alcanzando.. Tras estudiar 200 terremotos sucedidos en los últimos años en todo el Mediterráneo, una zona de gran variedad geológica y tectónica, concluyen que la magnitud de un terremoto podría estimarse utilizando sólo las señales recogidas durante los primeros segundos del seísmo.. Las ondas primarias (P) viajan a una velocidad de 6 kilómetros por segundo, y, por lo tanto, son capaces de llegar a 60 kilómetros del epicentro en 10 segundos.. Las secundarias, o S, que suelen ser las más destructivas, viajan más despacio, alrededor de 3.. 5 kilómetros por segundo, cubriendo alrededor de 17 kilómetros en 10 segundos.. Por tanto, una ciudad situada a unos 60 kilómetros del epicentro tendría alrededor de 15 segundos para prepararse para el impacto del seísmo, un tiempo resultado de la diferencia entre la llegada de la primera onda P a la estación sismológica más próxima al epicentro y la llegada de una onda S a una ciudad.. Aunque en los últimos años no se han registrado apenas seísmos de magnitud 7 en el Mediterráneo, los temblores de magnitud 6 pueden producir mucho daño, especialmente en áreas urbanizadas y los lugares en donde abundan viejas estructuras arquitectónicas, algo muy típico de la cuenca mediterránea.. Los investigadores observan que los sistemas de detección temprana del terremoto pueden también ayudar a atenuar los efectos de los desastres que provoca un terremoto, tales como los fuegos, las explosiones, los derrumbamientos, y los tsunamis, que pueden en muchos casos ser más devastadores que el terremoto en sí mismo..

An Early Warning System for Earthquakes.. Scientists Try to Give People Crucial Seconds to Take Cover.. By Ned Potter.. ABC News.. Dec.. 4, 2006 - What if an earthquake were coming, and you had just a little bit of warning? It might be only 15 seconds, maybe 30 - but it might be enough time to take cover under a table, or find the safety offered by a door frame.. Italian scientists say they have figured out a way to measure the shock waves from a quake just two seconds after they begin, and, from that, calculate the earthquake's strength, location, and potential for damage in populated regions.. American researchers have been at work on this as well, hoping to set up an early warning system in California and other earthquake-prone areas.. Faster Than a Speeding P-Wave If researchers succeed, they might be able to place seismometers up and down fault lines, and measure the P-waves the primary shock waves from an earthquake several critical seconds before they reach the places where people live.. P-waves may be useful for warnings; they are not nearly as strong as secondary vibrations known as S-waves that do most of the damage.. It typically takes about 10 seconds for P-waves to spread 40 miles.. S-waves travel about half as fast.. But a warning signal, transmitted electronically from a seismometer near the epicenter, would spread at the speed of light.. That could mean extra time for gas companies to close automatic valves on their supply pipes, electric companies to isolate the vulnerable sections of their grid and people to run for cover.. Earthquakes are, by nature, chaotic.. Many geologists have been skeptical that the first P-waves can tell very much about the strong vibrations to follow.. But the new research suggests they're reliable for setting off warnings.. We can determine the magnitude within a couple of seconds of initiation of rupture and predict the ground motion from seconds to tens of seconds before it's felt, said Richard Allen, an assistant professor of earth and planetary science at the University of California, Berkeley, when he and colleagues published a paper on early warnings last year in the journal Nature.. ElarmS Allen is part of a team that has been at work on a project called ElarmS short for Earthquake Alarms Systems.. They calculate that in the worst earthquakes, a well-designed system could give San Francisco, for instance, an extra 20 seconds to put systems in safe mode.. That is, if the warnings are accurate.. Nobody wants a very expensive system that constantly gives false alarms.. ElarmS has been held up by political arguments over its cost effectiveness.. That's where the Italian researchers come in.. Writing in an upcoming issue of the journal Geophysical Research Letters, they report that in just the first two seconds after a major earthquake, they can get enough data for an accurate picture of where it will spread, and how violent it will be.. They say they tested their calculations on more than 200 earthquakes in the Mediterranean Basin, and found that the early P-waves were very reliable as indications of the stronger S-waves to follow.. The earthquake size can be, therefore, estimated, they write, while the rupture itself is still propagating and rupture dimension is far from complete.. Could all this make a difference when a major earthquake strikes? Science has been frustrated in its attempts to predict when one will happen, so, as many geologists argue, every nanosecond's warning will help..
