    Isotropic events observed with a borehole array in the Chelungpu fault zone, Taiwan (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-07-28
    Beschreibung: Shear failure is the dominant mode of earthquake-causing rock failure along faults. High fluid pressure can also potentially induce rock failure by opening cavities and cracks, but an active example of this process has not been directly observed in a fault zone. Using borehole array data collected along the low-stress Chelungpu fault zone, Taiwan, we observed several small seismic events (I-type events) in a fluid-rich permeable zone directly below the impermeable slip zone of the 1999 moment magnitude 7.6 Chi-Chi earthquake. Modeling of the events suggests an isotropic, nonshear source mechanism likely associated with natural hydraulic fractures. These seismic events may be associated with the formation of veins and other fluid features often observed in rocks surrounding fault zones and may be similar to artificially induced hydraulic fracturing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ma, Kuo-Fong -- Lin, Yen-Yu -- Lee, Shiann-Jong -- Mori, Jim -- Brodsky, Emily E -- New York, N.Y. -- Science. 2012 Jul 27;337(6093):459-63. doi: 10.1126/science.1222119.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, and Institute of Geophysics, National Central University, Taiwan, Republic of China. fong@ncu.edu.tw〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22837526" target="_blank"〉PubMed〈/a〉

    Stress state in the largest displacement area of the 2011 Tohoku-Oki earthquake (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-02-09
    Beschreibung: The 2011 moment magnitude 9.0 Tohoku-Oki earthquake produced a maximum coseismic slip of more than 50 meters near the Japan trench, which could result in a completely reduced stress state in the region. We tested this hypothesis by determining the in situ stress state of the frontal prism from boreholes drilled by the Integrated Ocean Drilling Program approximately 1 year after the earthquake and by inferring the pre-earthquake stress state. On the basis of the horizontal stress orientations and magnitudes estimated from borehole breakouts and the increase in coseismic displacement during propagation of the rupture to the trench axis, in situ horizontal stress decreased during the earthquake. The stress change suggests an active slip of the frontal plate interface, which is consistent with coseismic fault weakening and a nearly total stress drop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Weiren -- Conin, Marianne -- Moore, J Casey -- Chester, Frederick M -- Nakamura, Yasuyuki -- Mori, James J -- Anderson, Louise -- Brodsky, Emily E -- Eguchi, Nobuhisa -- Expedition 343 Scientists -- New York, N.Y. -- Science. 2013 Feb 8;339(6120):687-90. doi: 10.1126/science.1229379.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Kochi Institute for Core Sample Research, Japan Agency for Marine-Earth Science and Technology, Nankoku, Japan. lin@jamstec.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23393262" target="_blank"〉PubMed〈/a〉

    Low coseismic friction on the Tohoku-Oki fault determined from temperature measurements (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-12-07
    Beschreibung: The frictional resistance on a fault during slip controls earthquake dynamics. Friction dissipates heat during an earthquake; therefore, the fault temperature after an earthquake provides insight into the level of friction. The Japan Trench Fast Drilling Project (Integrated Ocean Drilling Program Expedition 343 and 343T) installed a borehole temperature observatory 16 months after the March 2011 moment magnitude 9.0 Tohoku-Oki earthquake across the fault where slip was ~50 meters near the trench. After 9 months of operation, the complete sensor string was recovered. A 0.31 degrees C temperature anomaly at the plate boundary fault corresponds to 27 megajoules per square meter of dissipated energy during the earthquake. The resulting apparent friction coefficient of 0.08 is considerably smaller than static values for most rocks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fulton, P M -- Brodsky, E E -- Kano, Y -- Mori, J -- Chester, F -- Ishikawa, T -- Harris, R N -- Lin, W -- Eguchi, N -- Toczko, S -- Expedition 343, 343T, and KR13-08 Scientists -- New York, N.Y. -- Science. 2013 Dec 6;342(6163):1214-7. doi: 10.1126/science.1243641.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, University of California, Santa Cruz, CA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24311684" target="_blank"〉PubMed〈/a〉

    Continuous permeability measurements record healing inside the Wenchuan earthquake fault zone (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-07-03
    Beschreibung: Permeability controls fluid flow in fault zones and is a proxy for rock damage after an earthquake. We used the tidal response of water level in a deep borehole to track permeability for 18 months in the damage zone of the causative fault of the 2008 moment magnitude 7.9 Wenchuan earthquake. The unusually high measured hydraulic diffusivity of 2.4 x 10(-2) square meters per second implies a major role for water circulation in the fault zone. For most of the observation period, the permeability decreased rapidly as the fault healed. The trend was interrupted by abrupt permeability increases attributable to shaking from remote earthquakes. These direct measurements of the fault zone reveal a process of punctuated recovery as healing and damage interact in the aftermath of a major earthquake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Lian -- Li, Hai-Bing -- Brodsky, Emily E -- Xu, Zhi-Qing -- Kano, Yasuyuki -- Wang, Huan -- Mori, James J -- Si, Jia-Liang -- Pei, Jun-Ling -- Zhang, Wei -- Yang, Guang -- Sun, Zhi-Ming -- Huang, Yao -- New York, N.Y. -- Science. 2013 Jun 28;340(6140):1555-9. doi: 10.1126/science.1237237.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, University of California, Santa Cruz, CA 95064, USA. lxue3@ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23812711" target="_blank"〉PubMed〈/a〉

    Low coseismic shear stress on the Tohoku-Oki megathrust determined from laboratory experiments (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-12-07
    Beschreibung: Large coseismic slip was thought to be unlikely to occur on the shallow portions of plate-boundary thrusts, but the 11 March 2011 Tohoku-Oki earthquake [moment magnitude (Mw) = 9.0] produced huge displacements of ~50 meters near the Japan Trench with a resultant devastating tsunami. To investigate the mechanisms of the very large fault movements, we conducted high-velocity (1.3 meters per second) friction experiments on samples retrieved from the plate-boundary thrust associated with the earthquake. The results show a small stress drop with very low peak and steady-state shear stress. The very low shear stress can be attributed to the abundance of weak clay (smectite) and thermal pressurization effects, which can facilitate fault slip. This behavior provides an explanation for the huge shallow slip that occurred during the earthquake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ujiie, Kohtaro -- Tanaka, Hanae -- Saito, Tsubasa -- Tsutsumi, Akito -- Mori, James J -- Kameda, Jun -- Brodsky, Emily E -- Chester, Frederick M -- Eguchi, Nobuhisa -- Toczko, Sean -- Expedition 343 and 343T Scientists -- New York, N.Y. -- Science. 2013 Dec 6;342(6163):1211-4. doi: 10.1126/science.1243485.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Life and Environmental Sciences, University of Tsukuba, Tsukuba, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24311683" target="_blank"〉PubMed〈/a〉

    Structure and composition of the plate-boundary slip zone for the 2011 Tohoku-Oki earthquake (2013)

    Publikationsdatum: 2013-12-07
    Beschreibung: The mechanics of great subduction earthquakes are influenced by the frictional properties, structure, and composition of the plate-boundary fault. We present observations of the structure and composition of the shallow source fault of the 2011 Tohoku-Oki earthquake and tsunami from boreholes drilled by the Integrated Ocean Drilling Program Expedition 343 and 343T. Logging-while-drilling and core-sample observations show a single major plate-boundary fault accommodated the large slip of the Tohoku-Oki earthquake rupture, as well as nearly all the cumulative interplate motion at the drill site. The localization of deformation onto a limited thickness (less than 5 meters) of pelagic clay is the defining characteristic of the shallow earthquake fault, suggesting that the pelagic clay may be a regionally important control on tsunamigenic earthquakes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chester, Frederick M -- Rowe, Christie -- Ujiie, Kohtaro -- Kirkpatrick, James -- Regalla, Christine -- Remitti, Francesca -- Moore, J Casey -- Toy, Virginia -- Wolfson-Schwehr, Monica -- Bose, Santanu -- Kameda, Jun -- Mori, James J -- Brodsky, Emily E -- Eguchi, Nobuhisa -- Toczko, Sean -- Expedition 343 and 343T Scientists -- New York, N.Y. -- Science. 2013 Dec 6;342(6163):1208-11. doi: 10.1126/science.1243719.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Tectonophysics, Department of Geology and Geophysics, Texas A&M University, College Station, TX 77843, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24311682" target="_blank"〉PubMed〈/a〉

    Outward-dipping ring-fault structure at rabaul caldera as shown by earthquake locations (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-01-09
    Beschreibung: The locations of a large number of earthquakes recorded at Rabaul caldera in Papua New Guinea from late 1983 to mid-1985 have produced a picture of this active caldera's structural boundary. The earthquake epicenters form an elliptical annulus about 10 kilometers long by 4 kilometers wide, centered in the southern part of the Rabaul volcanic complex. A set of events with well-constrained depth determinations shows a ring-fault structure that extends from the surface to a depth of about 4 kilometers and slopes steeply outward from the center of the caldera. This is the first geophysical data set that clearly outlines the orientation of an active caldera's bounding faults. This orientation, however, conflicts with the configuration of many other calderas and is not in keeping with currently preferred models of caldera formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mori, J -- McKee, C -- New York, N.Y. -- Science. 1987 Jan 9;235(4785):193-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17778631" target="_blank"〉PubMed〈/a〉

    Iron encrustations on filamentous algae colonized by Gallionella-related bacteria in a metal-polluted freshwater stream (2015)
    Copernicus
    Details
    Publikationsdatum: 2015-05-22
    Beschreibung: Filamentous macroscopic algae were observed in slightly acidic to circumneutral (pH 5.9~6.5) metal-rich stream water that leaked out in a former uranium-mining district (Ronneburg, Germany). These algae differ in color and morphology and were encrusted with Fe-deposits. To elucidate the potential interaction with Fe(II)-oxidizing bacteria (FeOB), we collected algal samples at three time points during summer 2013 and studied the algae-bacteria-mineral compositions via confocal laser scanning microscopy (CLSM), scanning electronic microscopy, Fourier transform infrared spectra, and a 16S and 18S rRNA gene based bacterial and algae community analysis. Surprisingly, sequencing analysis of 18S rRNA gene regions of green and brown algae revealed high homologies with the yellow-green freshwater algae Tribonema (99.9~100%). CLSM imaging indicates a loss of active chloroplasts in the algae cells, which may be responsible for the change in color in Tribonema. Fe(III)-precipitates on algal cells identified as ferrihydrite and schwertmannite were associated with microbes and extracellular polymeric substances (EPS)-like glycoconjugates. While the green algae were fully encrusted with Fe-precipitates, the brown algae often exhibited discontinuous series of precipitates. This pattern was likely due to the intercalary growth of algal filaments which allowed them to avoid fatal encrustation. 16S rRNA gene targeted studies based on DNA and RNA revealed that Gallionella-related FeOB dominated the bacterial RNA and DNA communities (70–97 and 63–96%, respectively) suggesting their contribution to Fe(II) oxidation. Quantitative PCR revealed higher Gallionella-related 16S rRNA gene copy numbers on the surface of green algae compared to the brown algae. The latter harbored a higher microbial diversity, including some putative predators of algae. Lower photosynthetic activities of the brown algae lead to reduced EPS production which may have enabled predator colonization. The differences observed between green and brown algae suggest that metal-tolerant Tribonema sp. provide suitable microenvironments for microaerophilic Fe-oxidizing bacteria. However, high levels of iron orchres can be fatal to the alga.
