Knowledge of frictional resistance along faults is important for understanding the
mechanics of earthquakes and faulting. The clearest in situ measure of fault friction
potentially comes from temperature measurements in boreholes crossing fault zones within a
few years of rupture. However, large temperature signals from frictional heating on faults
have...
Improved interpretations of the strength of the San
Andreas Fault near Parkfield, CA based on thermal data
require quantification of processes causing significant
scatter and uncertainty in existing heat flow data. These
effects include topographic refraction, heat advection by
topographically-driven groundwater flow, and uncertainty
in thermal conductivity. Here, we re-evaluate...
We estimate fluid sources around a subducted seamount along the northern Hikurangi subduction margin of New Zealand, using thermomechanical numerical modelling informed by wedge structure and porosities from multichannel seismic data. Calculated fluid sources are input into an independent fluid-flow model to explore the key controls on overpressure generation to...
Recent studies hypothesize that some submarine slides fail via pressure-driven slow-slip deformation. To test this hypothesis, this study derives pore pressures in failed and adjacent unfailed deep marine sediments by integrating rock physics models, physical property measurements on recovered sediment core, and wireline logs. Two drill sites (U1394 and U1399)...
