Bridges – Bridging Geodesy and Seismology

We started in 2016 to work on improving global crustal earthquake source analyses through a better integration of space-geodetic radar data products, in particular by using space-borne interferometric SAR, with classical teleseismic waveform data. Using earthquake near-field data as from InSAR and earthquake far-field data as teleseismic waveforms, we will be able to better resolve the rupture characteristics of shallow crustal earthquakes.

3D Earth – A Dynamic Living Planet

3D Earth will establish a global 3D model of the crust and upper mantle based on the analysis of satellite gravity and (electro-)magnetic missions in combination with seismological models and analyse the feedback between processes in Earth’s deep mantle and the lithosphere.

 

The prime objective is to integrate, for the first time, seismological models and satellite observation towards a consistent image of the crust and upper mantle in 3D. Satellite gravity and (electro-) magnetic data help to transfer velocity images towards composition and temperature that reflect the tectonic state and evolution of the Earth and offer a novel understanding of the processes that shape our planet.

Swarm

Swarm is a new satellite mission conducted by the European Space Agency. Three satellites measure the magnetic field of the Earth with an resolution of about 300 km km over the whole globe.

GOCE

The GOCE satellite measured the full gravity tensor with an accuracy of about 80 km. These fields are used to model the Moho, which is the major density contrast in the upper lithosphere. The exploration of the full tensor by modelling and inversion improves the detection of density contrasts in the crust and thus the resolution of subsurface models.

In particular, we are currently exploiting GOCE's gradient data to investigate the lithospheric structure of Antarctica. The international research project Opens external link in new windowGOCE+Antarctica combines these potential field data with recent seismological studies in an integrated and self-consistent 3D model of the Antarctic continent down to 400 km depth. The thermal and the isostatic state are of particular interest for the interaction between the solid earth and the cryosphere (Glacial Isostatic Adjustment). Furthermore, the results of this project are supposed to improve our knowledge of the geodynamic history of Antarctica.

Imosaga – Integrated Modeling of Satellite and Airborne Gravity data of Active Plate Margins

This is a follow up grant application of the NOGAPSGRAV project (Novel Geophysical And Petrological applications of new-generation Satellite-derived Gravity data with a focus on hazardous and frontier regions) within SPP 1257 and addresses the progress and continuationof the project based on the first GOCE & HALO data. It aims to interpret the 3D density and dynamic structure of active convergent plate boundaries of the South and Central American subduction zones as well as the Crete regions using satellite (GOCE), airborne (HALO) and terrestrial gravity data. The density, dynamic and flexural rigidity models based on GOCE gravity, gravity gradients and invariants will add new dimension to the interpretation of lithospheric structure, localization of strain accumulation along plate interface and delineation of regions of high seismic moment release.
