Seismology from space: geodetic observations and early warning of earthquakes

Start Date
End Date

    An RAS Specialist Discussion Meeting organised by Professor Peter Clarke (Newcastle)* and Professor Tim Wright (Leeds)
*Contact: peter.clarke_AT_newcastle.ac.uk In recent years the availability of high-rate (1 Hz sampling or faster) GPS/GNSS data, often telemetered in near-real-time, has enabled the observation of strong ground motions, teleseismic waves, and "permanent" co-seismic deformation in the immediate aftermath of an earthquake.  Likewise, multiple-mission InSAR data have facilitated the observation of surface deformation at lower temporal but much higher spatial resolution.  This meeting will bring the UK geodesy and seismology communities together to examine the prospects for these techniques to enhance our understanding of the earthquake rupture process and provide early warning of earthquake mechanism and magnitude for the mitigation of earthquake-related hazards such as tsunamis. 10:35 John Elliott (University of Oxford)Observations of recent earthquakes and the future of geodetic analysis of earthquakes under Sentinel11:25 Richard Allen (University of California)Earthquake Alert: Blending seismic and GPS data to reduce risk12:20 Discussion12:30 Lunch* and posters13:30 Susan Owen (NASA Jet Propulsion Laboratory, Pasadena, California)Integrating SAR, high-rate GPS, and seismology for natural hazard monitoring &
