Eléonore Stutzmann, from the Institut de Physique du Globe de Paris (IPGP), has been visiitng researcher at ICTJA-CSIC from 13th to 17th February. Stutzmann visit has been promoted by ICTJA-CSIC researcher Martin Schimmel.

This stage is another step of Stutzmann and Schimmel research which focused in using seismic noise to extract more information on Earth structure and dynamic processes. They are performing a long term collaboration on signal extraction from seismic noise and the detection and characterization of its sources.

During Stutzmann’s visit, it has been posible to finish a new paper on extracting signals at hum frequencies. Moreover, Stutzmann and Schimmel have been able to prepare the next stages of their research. “We have defined a new strategy for data analysis in order to apply our signal processing methods both on Earth and on other planets such as Mars, where a broadband seismometer will be installedn  in 2018 in the framework of the Insight mission“, says Éleonore Stutzmann who adds that “this entire procedure includes the development of codes, the set up of theoretical test data and an exhaustive testing of our methods”.

Stutzmann and Schimmel have perfomed a long-lasting collaboration for more than 10 years. “We have  the same scientific interests but different expertise and view points”, explains Martin Schimmel .”This makes our collaboration very efficient and allows us to solve the different problems at hand”.

Last summer, Eleonore Stutzmann stayed at the Institute for a week working hand-by-hand with Schimmel. Since then, they have finifished 3 publications and started new collaborations and research on related problems. In the last months, Schimmel was also a visiting researcher at IPGP for two times.

Schimmel and Stutzmann research is being performed in the framework of MISTERIOS and MIMOSA projects respectively. Eleonore Stutzmann is currently  the director of the IPGP Seismology group and former director of GEOSCOPE observatory.
