Several large earthquakes with magnitude higher than 8 on the Richter scale have already occurred along the margins between the Nazca and South American tectonic plates, under the ocean off Ecuador and Colombia. This region is vulnerable, all the more so because since the 1980s, Ecuador’s oil export terminal is sited within it. More information is needed on this zone of extremely high seismic risk. For this reason, two scientific campaigns, “Amadeus” and “Esmeraldas” were launched on 3 February and will run until 6 April 2005.
These campaigns, conducted by the mixed research unit (UMR) Geosciences-Azur (involving the IRD, CNRS, Universities Pierre et Marie Curie and Nice Sophia-Antipolis) working jointly with the University of Bordeaux, the Marine Technology Unit of the CSIC (Higher Council for Scientific Research) at Barcelona, and its international partners: Canadian (University of Victoria, PGC), Colombian (DIMAR, EAFIT and Caldas Universities, and INGEOMINAS) and Ecuadorian (INOCAR, EPN, Petroproduction) have the objective of studying the natural hazards associated with the large subduction earthquakes, submarine avalanches and tsunamis they trigger. The ocean-going campaigns are being conducted on the IFREMER research ship Atalante.
In 1906, a strong earthquake of 8.8 magnitude shook this part of the world. It was induced by the slipping of the Nazca plate under the North Andean margin. The two plates converge at an average rate of 5.5 cm/year. The slipping is expressed as a fracture zone about 500 km long. Reactivation occurred by earthquakes in 1942, 1958 and 1979, of magnitude 7.7 to 8.2, which provoked large tsunamis and submarine sediment slides.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
