Evidence of mud volcanism due to the rapid compaction of martian tsunami deposits in southeastern Acidalia Planitia, Mars

Thumbprint terrain was first recognized in Viking Orbiter data and described as sets of alternating continuous parallel ridges depressions up to several tens kilometres length, with high low albedo respectively. We performed a geomorphological analysis these features using both Context Camera High Resolution Imaging Science Experiment images, well topographic profiles based on Mars Laser Altimeter data, the aim provide an origin for thumbprint constrain geological evolution southeastern Acidalia Planitia. The identification runup lobate deposits, coupled putative presence Late Hesperian ocean northern lowlands, led speculations that evidence tsunamis may be present geologic record area. There are hypotheses have been proposed previously explain include ice-related, volcanic-related, liquefaction mud-volcanism driven processes. However, tsunami-related provides strong framework energy required associated lobes flow uphill leaving peripheral termination result viscosity. Numerical simulations indicate - prior their emplacement sustained velocities, thereby lending further support tsunami hypothesis from Lomonosov crater impact. Wave interference patterns, formed during propagation over around prominent topography, likely spatial arrangement. sedimentary cones are, herein, considered mud volcanoes related occurred
