Title: Squeezing Marsquakes Out of Groundwater

Abstract

Pore pressure in aquifers confined below a cryosphere will increase as Mars cools and the cryosphere thickens. Increased pore pressure decreases the effective stress and hence promotes seismicity. We calculate the rate of pore pressure change from cooling of Mars's interior and the modulation of pore pressure from solar and Phobos tides and barometric loading. Using the time-varying pressure and tidal stresses, we compute Coulomb stress changes and the expected seismicity rate from a rate-and-state friction model. Seismicity rate will vary by several tens of percent to 2 orders of magnitude if the mean pore pressure is within 0.2 and 0.01 MPa of lithostatic, respectively. Seismic events promoted by high pore pressure may be tremor-like. Documenting (or not) tidally modulated shallow seismicity would provide evidence for (or against) water-filled confined aquifers, that pore pressure is high, and that the state of stress is close to failure—with implications for processes that can deliver water to the Martian surface.

Constraints on Friction, Dilatancy, Diffusivity, and Effective Stress From Low-Frequency Earthquake Rates on the Deep San Andreas Fault

Journal Article Beeler, N. M. ; Thomas, Amanda ; Bürgmann, Roland ; ... - Journal of Geophysical Research. Solid Earth

Families of recurring low-frequency earthquakes (LFEs) within nonvolcanic tremor on the San Andreas Fault in central California are sensitive to tidal stresses. LFEs occur at all levels of the tides, are strongly correlated and in phase with the ~200 Pa shear stresses, and weakly and not systematically correlated with the ~2 kPa tidal normal stresses. Here, we assume that LFEs are small sources that repeatedly fail during shear within a much larger scale, aseismically slipping fault zone and consider two different models of the fault slip: (1) modulation of the fault slip rate by the tidal stresses or (2) episodicmore »« less

Formation of Martian flood features by release of water from confined aquifers

Journal Article Carr, M H - J. Geophys. Res.; (United States)

Many large Martian channels arise full born from discrete areas of chaotic terrain. Estimates of peak discharges based on channel dimensions range from 10/sup 6/ to 10/sup 8/ m/sup 3//s. It is here proposed that the large channels were eroded by water released rapidly, under great pressure, from deeply buried aquifers. Early in the planet's history the old cratered terrain was probably highly permeable to depths of several kilometers as a result of its volcanic origin and intense brecciation by meteorite impact. Extensive dissection of the old cratered terrain by fine channels suggests that fluvial action was widespread at thatmore »« less

Fortnightly modulation of San Andreas tremor and low-frequency earthquakes

Journal Article van der Elst, Nicholas J. ; Delorey, Andrew A. ; Shelly, David R. ; ... - Proceedings of the National Academy of Sciences of the United States of America

Earth tides modulate tremor and low-frequency earthquakes (LFEs) on faults in the vicinity of the brittle-ductile (seismic-aseismic) transition. Our response to the tidal stress carries otherwise inaccessible information about fault strength and rheology. We analyze the LFE response to the fortnightly tide, which modulates the amplitude of the daily tidal stress over a 14-d cycle. LFE rate is highest during the waxing fortnightly tide, with LFEs most strongly promoted when the daily stress exceeds the previous peak stress by the widest margin. This pattern implies a threshold failure process, with slip initiated when stress exceeds the local fault strength. Furthermore,more »« less

Using Water-Level Models to Conceptualize Groundwater-Flow Systems: Examples from the Nevada National Security Site - 17044

Conference Jackson, Tracie R.

Analysis of water-level trends in well hydro-graphs can be used to better understand and conceptualize a groundwater-flow system. A water-level trend reflects the summation of all natural and anthropogenic stresses acting on the aquifer at the well location. Common stresses include recharge, evapotranspiration, barometric pressure, earth tides, and pumping. A water-level model (WLM) can be used as a tool to distinguish which stresses are affecting the trend and quantify the impact of each stress on the trend. A WLM is an analytical model that fits measured water levels to a synthetic curve representing the sum of one or more time-seriesmore »« less
THE ORBITS AND MASSES OF THE MARTIAN SATELLITES AND THE LIBRATION OF PHOBOS

Journal Article Jacobson, R. A. - Astronomical Journal (New York, N.Y. Online)

This paper reports on an update to the orbits and masses of the Martian satellites Phobos and Deimos. We obtained the orbits by fitting a numerical integration to all available Earth-based astrometry through the opposition of 2003, spacecraft imaging observations through 2007, and the Doppler tracking of the Viking and Phobos 2 spacecraft; the Doppler data provide information on the satellite masses. Our dynamical model included the figure acceleration due to a librating Phobos; we determined the amplitude of the forced libration. We also took into account the secular acceleration of Phobos due to the tide that it raises onmore »« less
