It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.

We will have a special issue in JGR titled "Creep on continental faults and subduction zones: Geophysics, geology, and mechanics” soon. The collection is now opened for submissions on March 1, 2019, and submissions are due on March 1, 2020.
The description is listed below for your information:
Fault creep has been observed worldwide in tectonically-active continental regions, mostly on strike-slip faults and on a few thrust and normal faults, as well as on many subduction thrusts. With improved resolution of fault kinematics using dense geodetic and seismologic data, the nature of fault creep has been intensively investigated on a variety of continental faults and subduction zones.
Geophysical observations and computational models are commonly used to document where aseismic slip occurs in space and time. Complementary geologic field observations provide insight into how aseismic slip operates under various pressure and temperature condition. In rock mechanics experiments, the frictional behavior of fault materials, from the macro-scale down to the nanoscale, has been studied to better understand what enables a fault to creep. At the 2018 AGU fall meeting, special sessions on “The nature of creeping faults: Where, how, and why they slip slowly” and “Interplay Between Seismic and Aseismic Slip: Implications for Fault Physics” highlighted multi-disciplinary contributions from geological, geophysical, experimental, and modeling studies of aseismic slip in various fault systems, which serves as the motivation for this proposed collection of papers. Is there a universal rule for signatures, influence, and physical mechanisms of aseismic slip in different tectonic setting? How much do we know about the similarities and differences between shallow creep (upper few km) and deep creep (>10 km deep) from microstructures, mineral composition, lithologic properties and conditions, geodesy, and geophysical methods? What is the role of deep and shallow creep in the size and timing of large earthquakes? And how does the nature of creeping faults change with the style of faulting, loading rate, and other factors?
This special issue aims at collecting multi-disciplinary contributions from geological, geophysical, experimental, and modeling studies of creeping faults. Synthesis papers using integrated works for individual creeping faults/subductiuon zone are encouraged as well.
