Goals and Mission: Within the GFZ, Section 2.4 provides core seismological competence and infra-structure. A reliable assessment of the earthquake hazard requires a fundamental understanding of the underlying geodynamic processes. We examine these on a lithospheric scale by application and development of seismological methods for imaging the upper mantle and crust. We also locate and characterise seismicity on a local and regional scale as a marker of stress and deformation processes.
We run a program, GEOFON, with which we seek to facilitate cooperation in seismological research and earthquake and tsunami hazard mitigation by operating a global network of stations, by providing rapid transnational access to seismological data and source parameters of large earthquakes, by keeping these data accessible in the long term and by developing and distributing communication and processing software. Mitigation of the effects of major earthquakes by early warning from tsunamis and the provision of prompt information for governmental agencies, NGOs, the media and the general public requires rapid determination of earthquake parameters. We develop methods for the fast automatic location and determination of magnitude and other parameters (moment tensor, rupture propagation), and provide a bulletin for all major earthquakes.
As member of the SPIN consortium GFZ is organising the second training event in Carcans close to Bordeaux. A short course on seismic instrumentation will introduce classical seismological instruments as well as novel optical measurement principles like fibre optic gyros and distributed acoustic sensing. The subsequent workshop will focus on monitoring and understanding of time-dependent behavior of the Earth’s crustal materials.
