COMET wins Geol Soc 2015 awards
Two COMET scientists are to receive prestigious awards from the Geological Society of London.

The Society, which has been recognising significant achievements in the Earth sciences since 1831, will be presenting its Wollaston Medal (its highest award, for impacts on pure or applied geology) to COMET’s James Jackson, Professor of Active Tectonics at the University of Cambridge.
Professor Jackson’s work includes research into active tectonics in New Zealand, Iran, Turkey, Greece and Tibet, where he has made vital contributions to understanding the evolution and deformation of the continents, from individual faults to mountain belts.
Professor Geoff Wadge of the University of Reading will meanwhile receive the Murchison Medal, awarded to geologists who have contributed significantly to ‘hard’ rock studies. Professor Wadge is being recognised for his contributions to geology and remote sensing, including research into volcanology, Caribbean tectonics, and volcanic hazards and risk assessment. The awards will be presented by Geological Society President Professor David Manning at President’s Day on 3 June 2015.

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.
Earthquake monitoring gets boost from new satellite
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.

Austin Elliott joins COMET from UC Davis
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.
