Core 40 is characterized by the preferred orientation of clay particles along distributed shear planes, resulting in the development of a scaly fabric, similar to that from the Tohoku plate boundary fault documented by IODP Expedition 343.
Part of the difference, in the computation of the critical facility, is determined by the introduction of some faults without documented seismicity.
The internal structure of the fault zones, documented here with emphasis on the Porcupine Destor fault zone, consists of isoclinally folded, strongly schistose, highly metamorphosed rock, cross-cut by numerous fault segments.
The fault sets documented in the study area are arranged in two kinematically-compatible fault networks.
At Kitaamagi, in the easternmost part of the Uto segment of the Futagawa fault zone, we documented two sets of ruptures trending ENE WSW in an isolated area with 500 600 m long about 3 km from the nearest surface ruptures in the adjoining Futagawa segment (Fig. 4a).
A brief evaluation of the two fault signature generation techniques is presented and the performance of the area error method is documented using the fault classification index (FCI) presented in Part I of the series.
She has her faults, easily described, often documented — though, for the most part, the worst accusations against her have turned out to be fiction.
This may also be the case for megasplay faults branching from the plate boundary such as in the Nankai Trough, where fault thickness and roughness are documented to be variable along the fault (Yamada et al. 2013).
Surface ruptures generally followed previously documented active fault traces, except in the northeastern and southwestern sections of the Futagawa segment.
