A member of the Macroseismic Response Group in the village of Le Teil during the 5.2 Mlv earthquake mission near Montélimar on November 11, 2019

2019-11-21

Description : On November 11, 2019 at 10:52 a 5.2 MLv earthquake occurred near Montélimar. Between Monday 18 and Friday 22 November, a team from the Macroseismic Response Group (BCSF), divided into pairs or groups of three, inspected more than 20 municipalities, met with elected officials and sometimes with the fire brigade. In most cases, they observe cracks, but in the most affected areas of the Teil, some old buildings are largely collapsed. This photo shows a member of the Macroseismic Response Group in the village of Le Teil during the 5.2 Mlv earthquake mission near Montélimar on November 11, 2019. The macroseismic response group intervenes at earthquake sites to assess the intensity of the earthquake, based on the effects of the earthquake on structures, buildings and individual houses. These field observations complement the testimonies provided by citizens on the france-seisme site. They are one of the elements that contribute to the establishment of the state of natural disaster by the authorities. The macroseismic survey also complements the other analyses carried out by scientists within the community of the French seismological and geodetic network Résif, in particular within the framework of its Transversal Seismicity Action. Résif is a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Inner Earth. Résif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Résif is integrated into European (EPOS - European Plate Observing System) and global systems of instruments for imaging the Earth's interior as a whole and studying many natural phenomena.
