Seismic sources of InSight marsquakes and seismotectonic context of Elysium Planitia, Mars

A. W. B. Jacob, Matthieu Plasman, Clément Perrin, Nobuaki Fuji et autres

Since early 2019, the InSight mission has proven that Mars is seismically active, with more than 900 seismic events recorded. Among them, several events have characteristics close to terrestrial tectonic earthquakes. Most of these events are located on the major graben system …

Geometry and Segmentation of Cerberus Fossae, Mars: Implications for Marsquake Properties

Clément Perrin, A. W. B. Jacob, Antoine Lucas, Robert Myhill et autres

The NASA InSight mission to Mars successfully landed on 26 November 2018 in Elysium Planitia. It aims to characterize the seismic activity and aid in the understanding of the internal structure of Mars. We focus on the Cerberus Fossae region, a giant …

Geometry and segmentation of Cerberus Fossae, Mars: implications for marsquake properties.

Clément Perrin, A. W. B. Jacob, Antoine Lucas, Robert Myhill et autres

The dataset is made of three different files: - Perrin-et-al-Calculated-DEMs.zip : we use HiRISE stereo pair images (https://www.uahirise.org/) to compute high-resolution DEMs along the Cerberus Fossae system using the SOCET SET mapping software (©BAE Systems). The stereo images are selected at different …

Seasonal seismic activity on Mars

Martin Knapmeyer, S.C. Stähler, I. J. Daubar, F. Forget et autres

The rate of occurrence of High Frequency (HF) marsquakes, as recorded by InSight at Homestead Hollow, Elysium Planitia, increased after about LS=33∘, and ceased almost completely by LS=187∘, following an apparently seasonal variation with a peak rate near aphelion. We define seismic …

First Focal Mechanisms of Marsquakes

Nienke Brinkman, Simon C. Stähler, Domenico Giardini, Cédric Schmelzbach et autres

Abstract Since February 2019, NASA's InSight lander is recording seismic signals on the planet Mars, which, for the first time, allows to observe ongoing tectonic processes with geophysical methods. A number of Marsquakes have been located in the Cerberus Fossae graben system …
