In the Netherlands, local authorities are looking to satellite observations as a promising option for dike monitoring and to protect against dike failures. In a recently completed Terrafirma study, the IJsselmeer dikes were checked using radar data from ESA's Envisat satellite for the period 2003–10.
Like scars that remain on the skin long after a wound has healed, earthquake fault lines can be traced on Earth's surface long after their initial rupture. Typically, this line of intersection between the area where the fault slips and the ground is more complicated at the surface than at depth. But a new study of the April 4, 2010, El Mayor–Cucapah earthquake in Mexico reveals a reversal of this trend. While the fault involved in the event appeared to be superficially straight, the fault zone is warped and complicated at depth.

BJ-IWGIS 2011 is the eighth forum of this successful series and will take place for the first time outside Beijing. Its main goal is to become a prestigious and high quality international conference that brings together researchers, scientists, engineers, and practitioners to share experiences and research results, and to exchange ideas about all aspects of geo-information science and technology.The workshop series have provided invaluable opportunities for scientists, GIS developers and users to share thei
Satellite images have been essential for helping relief efforts in Japan following the massive quake that struck on 11 March. Now scientists are using ESA’s space radars to improve our understanding of tectonic events.
