Topography is one of the most important geophysical observations that can be made at the Earth’s surface. Recent advances in topographic measurements have significantly improved the spatial resolutions available to earth scientists. Combining new high-resolution topography with high-resolution imagery allows Earth’s surface to be explored in a virtual environment, and comparison of pre- and post-event datasets allows the retrieval of 3D earthquake deformation fields.
The meeting aims to expose to a wider audience the new data sets and methods of analysis for measuring continental topography and surface displacements, and provide a forum for discussion of new tectonic applications of high-resolution topography and imagery.
Europe’s Sentinel-1A spacecraft and its extraordinary images of slip from the South Napa earthquake herald a new era of space-based surveillance of faults.
On 24 August 2014, the San Francisco Bay area shook in an Mw = 6.0 earthquake, the region’s largest in 25 years. The tremors injured roughly 200 people, killed 1 person, and damaged buildings near the quake’s epicenter in the southern reaches of California’s Napa Valley. It also set off a scientific scramble to measure the fault’s movement and marked the dawn of a new age of earthquake satellite monitoring thanks to a recently launched spacecraft: the European Space Agency’s Sentinel-1A satellite.
COMET scientists explain why in an article published in EOS, the Earth and space science journal of the American Geophysical Union.
A warm welcome to Austin Elliott who has just arrived in Oxford to take up a postdoctoral position in remote sensing and field investigations of active faulting and past earthquakes with Dr Richard Walker & Prof Barry Parsons. Austin is well known for his AGU blog Trembling Earth in which he covers the latest earthquakes. He was previously a PhD student at UC Davis in <a href="http://geology.ucdavis ou acheter viagra sans ordonnance.edu/research/research_groups/strutec.php”>Earth & Planetary Sciences.
