SEISMIC WAVE PROPAGATION AND IMAGING IN COMPLEX MEDIA: A EUROPEAN NETWORK
(SPICE)

Project description

The SPICE Consortium aims at integrating institutions with specialisations in physical, mathematical, geological, and computational aspects of seismic wave propagation. The goal is to develop, verify and apply computational tools for wave propagation and imaging problems on all scales. With the novel computational algorithms we expect breakthroughs in:
- the determination of global Earth structure;
- the quantitative estimation of shaking hazard;
- the characterization and monitoring of reservoirs;
- understanding the structure and processes inside volcanoes;
- simulating the physical processes of earthquake rupture;
- and characterizing the small-scale properties of rocks.
The network undertakes to provide secondments for Early Stage and Experienced Researchers whose appointment will be financed by the contract.
Recruitment of young researchers (mostly of pre-doc level) is underway - ESR vacancies in Prague!
