A re-classification of Marsquakes based on P-wave coda

Alexander Stott, Ludovic Margerin, Marie Calvet, Raphael F. Garcia et autres

The seismic events recorded by the NASA InSight mission provide one of the best resources to probe the interior structure of Mars. At the same time, the identification of their source is crucial to understand the active geological processes taking place on …

Identification of new Marsquake clusters from P-wave coda analysis and implications for crustal structure and seismicity

Alexander Stott, Ludovic Margerin, Marie Calvet, R. Garcia et autres

Over the 1440-sol mission of the NASA InSight lander, more than 1900 seismic events (marsquakes) were recorded and catalogued by the Marsquake service [1]. These events have enabled the determination of both the bulk interior structure [e.g. 2,3,4] and hinted at more …

Complementary analyses further support a molten Basal Mantle Layer on Mars: A reply to Russell et al. (2026)

Henri Samuel, M. Drilleau, Vedran Lekić, Jessica C. E. Irving et autres

Seismic data offer a unique window into planetary interiors. Here, following a note from Russell et al. (2026), we provide further analysis to solidify our identification of a seismic phase detected by the InSight mission as one which interacts with a basal …

Lateral Variations in Lunar Crustal Thickness Inferred From Apollo Seismic and GRAIL Gravity Data

Xi Zhang, Taichi Kawamura, M. Drilleau, Philippe Lognonné et autres

Abstract The internal structure of the Moon is key to understanding its formation, evolution, and bulk composition. In particular, determining the structure of the crust–mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to …

Lunar Optical Very Broad Band: a high-performance seismometer for Moon deep interior study

S. de Raucourt, Frédéric Guattari, Gabrielle Chabaud, M. Drilleau et autres

More than 50 years after Apollo, the Moon deep interior structure is still not well known. Several seismic experiments are expected on the Moon surface in the coming year (Chang’e 7, Chandrayan, Artemis III, FSS and SPSS). All of those seismometers are …

Constraining the Thermochemical Structure of Mars Through Joint Inversion of Multidisciplinary Geophysical Data

M. Drilleau, Henri Samuel, O. Verhoeven, Attilio Rivoldini et autres

Abstract Understanding Mars' deep interior is essential to reconstruct its geological history, thermal evolution, and present‐day dynamics. To this end, the NASA InSight mission has provided unprecedented seismic observations. However, strong trade‐offs between temperature and composition in seismic interpretations continue to limit …

The Moon's Crust and Upper Mantle Discontinuities Revealed by Seismic Interferometry Methods Applied to Apollo Seismic Data

Arnau Torrent Duch, R. García, M. Drilleau

Abstract Seismic determination of the Moon's crustal thickness is crucial for understanding its formation, composition, and evolution. Additionally, crustal thicknesses below seismic stations serve as anchoring points for 3D crustal thickness maps derived from gravity and topography field variations. However, strong seismic …

European Collaboration for Lunar Investigation with Planetary Seismology and Electromagnetism (ECLIPSE): A European Initiative to Strengthen the International Lunar Seismic Network

M. Drilleau, Fabio Ferrari, Özgür Karatekin, Taïchi Kawamura et autres

Introduction:In response to the exploratory call for missions within ESA’s science program, we propose the ECLIPSE mission to deploy a European geophysical station with seismometers and electromagnetic sensors on the lunar surface. Although data from the Apollo seismic network and subsequent geodetic …

Detection of Marsquake Nests in InSight Data

R. García, Iona Clemente, M. Drilleau, Alexander Stott et autres

Abstract The seismometer of the InSight NASA discovery mission recorded more than 1,300 seismic events on Mars, grouped into different families according to their frequency content. Here, we present a method to detect quake nests based on time domain correlation of long‐duration …
