Philippe Lognonné

Philippe Lognonné has been developing two areas of research in seismology over the last thirty years. The first, linked to the exploration of telluric planets, has enabled him to refine models of the Moon's internal structure and gain a better understanding of the meteorite impact processes on our satellite. He is taking part in NASA's InSight mission, which deployed a geophysical observatory equipped with a seismometer on the surface of Mars at the end of 2018. In 2026, he will take part in a new NASA mission that will land one of the spare SEIS models on the Moon. His other research is associated with the observation, from space, of tsunamis and waves generated by earthquakes. This latest research is accompanied by theoretical work to better model the coupling between tsunamis, seismic waves and the Earth's atmosphere and ionosphere.
