Actualités Crise sismique dans les Pyrénées (ouest de Lourdes) Depuis la fin décembre 2012, l’on observe une crise sismique modérée dans les Pyrénées, dans une zone située au sud-ouest de Lourdes. Parmi plusieurs dizaine de petits séismes de magnitude locale voisine de 3.0, quatre séismes de magnitude plus importante ont été ressentis par la population. L’équipe de sismologie de l’Observatoire Midi-Pyrénées ( OMP ) s’est donc rendue sur place dès le 1 er janvier afin d’installer trois stations sismologiques temporaires au plus près des répliques , ceci afin d’assurer un suivi le plus fin possible de leur répartition.

Sciences : Depuis 1700, 34 tsunamis sur les côtes françaises
INFOGRAPHIE - S'il n'y a pas eu de vagues meurtrières, la présence des centrales nucléaires sur le littoral pose question. Pas moins de 34 tsunamis se sont produits le long des côtes métropolitaines depuis le XVIII e siècle dont 22 en Méditerranée, 4 en Atlantique et 8 en Manche. On en dénombre 28 en France d'outre-mer. C'est le recensement le plus complet à ce jour. Il a été réalisé par Jérôme Lambert et Monique Terrier, du Bureau des recherches géologiques et minières (BRGM). «Le catalogue va continuer à s'étoffer au cours des prochaines années», assure Jérôme Lambert, géophysicien et historien pour la circonstance.

Tremblement de terre: scénario catastrophe sur la Côte d'Azur
Satellite Photos of Haiti Before and After the Earthquake | Wire
<img src="http://www.wired.com/images_blogs/wiredscience/2010/01/haiti_1a.jpg" alt="" /> The pictures and video from on-the-ground reports in Haiti following the magnitude 7 earthquake Tuesday are truly heartbreaking. But it is difficult to imagine the full extent of the damage to that country and its capital, Port-au-Prince, in particular. These new satellite images released Wednesday by Google and GeoEye show the devastation from above, giving a new view of the severity of this disaster. We’ve posted some of the images here.
At least 1783 deaths worldwide resulted from earthquake activity in 2009. The deadliest earthquake of the year was a magnitude 7.5 event that killed approximately 1117 people in southern Sumatra, Indonesia on Sept. 30, according to the U.S. Geological Survey (USGS) and confirmed by the United Nations Office for Coordination of Humanitarian Affairs (OCHA). However, the number of earthquake-related fatalities in 2009 was far less than the 2008 count of over 88,000. The high number of fatalities in 2008 was primarily due to the devastating magnitude 7.9 earthquake that occurred in Sichuan, China on May 12. Although unrelated, the Sept. 30 Indonesian earthquake occurred a day after the year’s strongest earthquake, a magnitude 8.1 on Sept. 29 in the Samoa Islands region.

National Earthquake Information Center - NEIC
Earthquake Hazards Program National Earthquake Information Center - NEIC The mission of the National Earthquake Information Center (NEIC) is to determine rapidly the location and size of all destructive earthquakes worldwide and to immediately disseminate this information to concerned national and international agencies, scientists, and the general public. The NEIC compiles and maintains an extensive, global seismic database on earthquake parameters and their effects that serves as a solid foundation for basic and applied earth science research.

Fact Sheet 2006-3016: Earthquake Hazards--A National Threat
Earthquakes are one of the most costly natural hazards faced by the Nation, posing a significant risk to 75 million Americans in 39 States. The risks that earthquakes pose to society, including death, injury, and economic loss, can be greatly reduced by (1) better planning, construction, and mitigation practices before earthquakes happen, and (2) providing critical and timely information to improve response after they occur. As part of the multi-agency National Earthquake Hazards Reduction Program, the U.S. Geological Survey (USGS) has the lead Federal responsibility to provide notification of earthquakes in order to enhance public safety and to reduce losses through effective forecasts based on the best possible scientific information. <p style="text-align:right;color:#A8A8A8"></p>
The PAGER system provides fatality and economic loss impact estimates following significant earthquakes worldwide. Links to PAGER results for earthquakes occurring within the last 7 days are contained below. The earthquakes are color-coded by the higher of two impact scales - fatalities and economic losses. These impact scales are broken up into four categories.

The 2008 Great Southern California ShakeOut was based on a potential magnitude 7.8 earthquake on the southern San Andreas Fault— approximately 5,000 times larger than the magnitude 5.4 earthquake that shook southern California on July 29, 2008.
