Dear All,
The next Royal Astronomical Society "G" Discussion Meeting is of
interest to the solid-Earth community:
"Earthquake Mechanics and Supershear Rupture Speeds"
Organised by Shamita Das, University of Oxford.
Friday 13th May 0930-1315, RAS Lecture Theatre, Burlington House, Piccadilly
Summary: Even though the possibility that earthquakes can rupture
at speeds exceeding the shear wave speed of the medium was
theoretically shown in the 1970's; convincing observations have
only occurred in the last decade. Laboratory experiments have
shown how the associated “Mach fronts” can result in high ground
motion (analogous to the sonic boom generated by supersonic airplanes),
this has opened up a new insights for earthquake hazard assessment.
These advances will be discussed at this meeting.
Invited speakers include Raul Madariaga (ENS, Paris),
Ares Rosakis (Caltech), Michel Bouchon (Grenoble),
Ralph Archuleta (UC Santa Barbara), Andrea Bizzari (INGV, Rome),
Peter Mozco (Bratislava) and David Robinson (RAS Winton Capital Awardee 2010, Oxford).
Followed by the RAS Annual General Meeting, 1400 (RAS members only), then
RAS Ordinary Meeting, 1600-1800 including the Harold Jeffreys
Lecture by Dr Lyndsay Fletcher, "The Sun at high energies" (open to all).
both in the Geological Society lecture theatre, Burlington House, Piccadilly, London.
