The Kinetics of the Seismic Cycle

by Randolph T. Williams and Åke Fagereng 7 June 202214 September 2022

Large earthquakes are necessarily punctuated by some degree of strength recovery, such as “fault healing”, but does quartz cementation during fluid-fault interactions facilitate that process?

Gradual fault creep can be seen deforming the walls of this stadium at the University of California, Berkeley.

Clay Type, Not Just Content, Crucial for Fault Zone Permeability

by Michael Heap 14 February 202219 October 2022

Faults containing clays are often considered as barriers to fluid flow but new work shows that fault processes leading to the formation of clays can increase permeability relative to the host rock.
