“…Recent studies of fault rocks have revealed that a range of reaction products can be considered as seismic slip signatures, such as frictional devolatilization of carbonates (Collettini et al, ; Han et al, ; Rowe, Fagereng, et al, ) and hydrous silicates (Collettini et al, ; Lockner et al, ; Sheppard et al, ), trace element mobility (Ishikawa et al, ), maturation of organic material (Savage et al, ; Sheppard et al, ), fault mirrors (Kirkpatrick et al, ; McDermott et al, ; Siman‐Tov et al, , ; Viti et al, ), fluidized granular flow (Kirkpatrick & Shipton, ; Meneghini et al, ), clast‐cortex aggregates (Boullier et al, ; Boutareaud et al, , ), and amorphous material (Kirkpatrick et al, ). In addition, features formed under extreme transient stress conditions associated with the propagating tip of an earthquake rupture, such as injection veins (Rowe, Kirkpatrick, et al, ), pulverization (Mitchell et al, ), and fault breccias (Melosh et al, ), can also be preserved in rocks as seismic records (Rowe & Griffith, ).…”
