      Variability in magnitude of paleoearthquakes revealed by trenching and historical records, along the Haiyuan fault, China

      Jing Liu-Zeng, Yanxiu Shao, Yann Klinger, Kejia Xie, Daoyuang Yuan and Zhongsheng Lei

      Accepted manuscript online: 27 OCT 2015 09:27PM EST | DOI: 10.1002/2015JB012163

      Key Points

      • Historical accounts suggest paleo-earthquakes of markedly different magnitudes
      • Moderate magnitude events can be preserved in stratigraphy
    42. Earthquake rupture process recreated from a natural fault surface

      Tom Parsons and Diane L. Minasian

      Accepted manuscript online: 27 OCT 2015 05:00PM EST | DOI: 10.1002/2015JB012448

      Key Points

      • In-situ fault surface measured
      • Numerical model made directly from point cloud
      • Earthquake rupture recreated on model fault
    43. Fault-plane orientations of intermediate-depth and deep-focus earthquakes in the Japan-Kuril-Kamchatka Subduction Zone

      Linda M. Warren, Elena C. Baluyut, Timothy Osburg, Kristen Lisac and Siiri Kokkinen

      Accepted manuscript online: 22 OCT 2015 06:10AM EST | DOI: 10.1002/2015JB012463

      Key Points

      • Fault plane orientations correlate with slab geometry
      • Earthquakes in planar slab segments slip along a dominant fault orientation

      Constraining the geometries of small-scale heterogeneities: A case study from the Mariana region

      Jun Korenaga

      Accepted manuscript online: 11 OCT 2015 11:41PM EST | DOI: 10.1002/2015JB012432

      Key Points

      • A new array-based method for seismic data is developed to detect small-scale heterogeneities
      • The new method can also constrain the geometries of detected scatterers
      • A total of 39 scatterers are identified in the vicinity of the Mariana subduction zone

      Electrical image of subduction zone beneath northeastern Japan

      Masahiro Ichiki, Yasuo Ogawa, Toshiki Kaida, Takao Koyama, Makoto Uyeshima, Tomotsugu Demachi, Satoshi Hirahara, Yoshimori Honkura, Wataru Kanda, Toshio Kono, Masaki Matsushima, Takashi Nakayama, Syuichi Suzuki and Hiroaki Toh

      Accepted manuscript online: 8 OCT 2015 02:22PM EST | DOI: 10.1002/2015JB012028

      Key Points

      • Flow overturn toward the backarc in the mantle wedge is imaged by resistivity.
      • Fluid pathways from the slab top to lower crust are revealed beneath NE Japan.
      • The lower crust conductor requires at least 0.7 volume percent of fluid fraction.

      Mechanical behaviour and microstructure of simulated calcite fault gouge sheared at 20-600 °C: Implications for natural faults in limestones

      Berend A. Verberne, André R. Niemeijer, Johannes H. P. De Bresser and Christopher J. Spiers

      Accepted manuscript online: 4 SEP 2015 01:21AM EST | DOI: 10.1002/2015JB012292

      Key Points

      • Calcite fault gouge shows (unstable) velocity weakening at 100{degree sign}-550{degree sign}C
      • Transition from frictional slip to viscous flow at ~600{degree sign}C
      • Microstructures from tests showing stick-slip are indicative of plastic flow

      Accepted manuscript online: 24 JUL 2015 08:23AM EST | DOI: 10.1002/2015JB012245

      Key Points

      • We describe new instruments for making point measurements of fluid flow
      • We report 89 new neat flow measurements
      • Heat flow data from hydrothermal systems are critical
