“…They suggested that the Nojima fault was already initiated at $56 Ma. The active Median Tectonic Line (Figure 1) follows part of the boundary between the Ryoke and Sanbagawa terranes that were accreted in the Mesozoic [Hashimoto, 1991]. Therefore, a few active faults in central Japan reactivated the preexisting faults under the present-day stress regime.…”

“…In the study area, i.e., the eastern part of the southwest Japan arc, north-trending reverse faults and northwest-trending left-lateral and northeast-trending rightlateral strike-slip faults are densely distributed (Figure 1). The offsets of dated geomorphic features indicate slip rates in the order of 10 À1 to 10 0 mm/yr for such faults [Research Group for Active Faults of Japan, 1991]. Central Japan has a long historical earthquake record that has been systematically collected for several centuries [Usami, 2003;Ishibashi, 2004].…”

“…The World Stress Map (WSM) Project was the first coordinated effort to map tectonic stress fields worldwide [Zoback, 1992], and the WSM database released in 2008 [Heidbach et al, 2010] contains three times as much stress data as that of the 1992 database. Most of the data sets used to derive the stress fields in the project are geophysical data such as those derived from the focal-mechanism solutions of earthquakes and wellbore breakout.…”

“…Most of the data sets used to derive the stress fields in the project are geophysical data such as those derived from the focal-mechanism solutions of earthquakes and wellbore breakout. In contrast, geological data such as fault-slip data and volcanic-vent alignment accounted for only $10% of the total data [Zoback, 1992;Heidbach et al, 2010]. The geophysical data reveal stress fields on the time scales of 10 0 -10 2 years, whereas the geological data reveal stress fields over longer periods, usually 10 5 years or longer.…”

“…[3] Permanent regional strain in central Japan has been accommodated mainly by active faults, which form a dense network in the region [Research Group for Active Faults of Japan, 1991;Nakata and Imaizumi, 2002] (Figure 1). Since the 1995 Kobe earthquake, most of the long and fast-slipping faults in the region have been studied extensively through a national active-fault research program, which has produced one of the most comprehensive active-fault data sets in the world.…”

We analyzed 169 geological fault‐slip data from 37 active faults in central Japan to investigate the late Quaternary stress field stability. Modern stress states have been documented with unprecedented accuracy; however, their stability over time scales beyond instrumental observations is inadequately understood. Because the stress field has changed in the geological past, we compared present stress conditions in central Japan, determined from geophysical observations, with conditions determined by inverting the fault‐slip data from active faults that exhibited cumulative displacement for the past ∼105years. The maximum stress axis obtained from fault‐slip data trends ESE–WNW. This state of stress accounts for 97% of the data and supports the fact that oblique faults with reverse and strike‐slip senses are interlaced in the region. The optimal stress is similar to the present stress state, indicating that the stress field in central Japan has been uniform and stable over the past ∼105 years.

In situ stress control on microcrack generation and macroscopic extensional fracture in exhuming bedrock

et al. 2014

View full text Add to dashboard Cite

Crustal stresses beneath evolving alpine landscapes result from a combination of tectonic strain, bedrock exhumation, and topography. The stress field is regulated by elastic material properties and the brittle strength of critically stressed elements, particularly those within preexisting faults and intact rock. Combining Byerlee's law for crustal stresses with a recently developed trilinear fracture envelope, we propose an extension of the critically stressed crust concept to constrain in situ stresses through microcrack generation and extensional fracture propagation. A compilation of 814 global in situ stress measurements suggests microcrack development will limit long‐term rock strength, and maximum differential stresses in the upper ~1 km of the crust can be controlled by cohesive bedrock behavior. Using an elastoplastic, 2‐D finite‐difference model, we approximate in situ stress development within landscapes undergoing high rates of exhumation in both normal and reverse tectonic regimes. Critical near‐surface stresses in these environments are defined by the microcrack initiation threshold, estimated to be roughly one third of the unconfined compressive strength of intact rock, while stresses deeper in the crust adhere to Byerlee's law. Our models indicate that exhumation‐induced stresses limited by long‐term rock strength are the primary contributor to the near‐surface stress field, while topographic relief reduces stress near valley axes. Simulating glacial erosion then allows us to illustrate a path‐dependent relationship between critical stress development, fracture formation, and geomorphic processes. We find that glacial unloading can generate new microcracks in near‐surface bedrock, resulting in unstable macroscopic extensional (or “exfoliation”) fracture propagation during incision of U‐shaped alpine valleys.

Stress magnitude and orientation in the Potiguar Basin, Brazil: Implications on faulting style and reactivation

[1] We analyzed borehole breakout data and drilling-induced tensile fractures derived from resistivity image logs run at 10 oil wells to derive the orientation of the maximum horizontal stress S Hmax from the Potiguar Basin in the continental margin of Brazil. Stress magnitudes are derived from density logs for the vertical stress, mini-frac tests for the minimum horizontal stress S hmin , and rock strength laboratory analysis to estimate the S Hmax magnitudes. We compared these results with the stress regime and S Hmax orientation derived from nine earthquake series located in the crystalline basement, where seismicity is concentrated, and previous breakout data from the basin. In the basin, the S Hmax gradient is 20.0 MPa/km, and the S Hmax /S hmin ratio is 1.154, indicating a normal tectonic stress regime from 0.5 to 2.0 km, whereas the S Hmax gradient of 24.5 MPa/km and S Hmax /S hmin ratio of 1.396 indicate a transition from a normal to strike-slip stress regime at 2.5 to 4.0 km. The deeper stress regime in the basin is similar to that in the basement at 1-12 km depth. This transition of the tectonic stress regime is consistent with an incipient tectonic inversion in the basin. We note that the S Hmax orientation rotates from NW-SE in the western part of the Potiguar Basin to E-W in its central and eastern parts, roughly following the shoreline geometry, indicating that local features such as flexural stresses influence the local (scale < 100 km) stress pattern. We also conclude that the basement is critically stressed, but not the basin.
