Estimates of seismic activity in the Cerberus Fossae region of Mars
[1] The 2016 NASA InSight lander is the first planetary mission designed to study the deep interior of Mars. InSight’s Seismic Experiment for Interior Structure (SEIS) package will quantify global and regional seismic activity and determine parameters like core properties, mantle composition, and Martian lithospheric thickness. An improved understanding of the location, magnitude, and frequency...
متن کاملAcheron Fossae, Mars: Evidence of Fluvial Activity and Mass Flow
Introduction: Acheron Fossae is an arcuate, topographically high piece of ancient terrain north of Olympus Mons along the boundary with the northern plains. The terrain consists of an older, Noachian-aged piece of crust that was uplifted and extensively faulted. Subsequently, a variety of modification processes have occurred including fluvial erosion, possible ponding of water, mass movement of...

متن کاملGeneration of recent massive water floods at Cerberus Fossae, Mars by dike emplacement, cryospheric cracking, and confined aquifer groundwater release
[1] Previous studies noted the close association of geologically very recent lava flows and fluvial channels emanating from Cerberus Fossae. To assess these relationships, we outline a model of magmatic dike emplacement that involves 1) surface fractures and localized volcanic eruptions, 2) attendant cryospheric cracking to fracture the surface and release pressurized groundwater confined benea...
متن کاملMedusae Fossae Formation: New perspectives from Mars Global Surveyor
[1] The nature and origin of the Medusae Fossae Formation (MFF) on Mars has been debated since the return of the first Viking images. The MFF’s young age, distinctive surface texture, and lack of obvious source have prompted multiple hypotheses for its origin. This study uses data from the Mars Global Surveyor (MGS) mission to examine the MFF at all available scales. We discuss and quantify obs...
