Intermittent Slip Along the Alto Tiberina Low-Angle Normal Fault in Central Italy
<p>Small magnitude events have regularly shaken the 50-km-long Alto Tiberina low-angle normal fault (ATF) in central Italy. Above it, few kilometers long syn- and antithetic higher-angle normal faults were active with many moderate seismic sequences and 10 times more events than ATF between 2010 and 2014. To better understand the fault system interaction, we apply a technique for finding events which match predefined templates to improve the ATF seismic catalog. The results indicate that productive sequences in the shallower high-angle faults often hamper the detection of microseismicity along with the ATF and that events are released at intermittent rates. Moreover, the seismic activity is mainly organized in clusters of small earthquakes lasting days or months with no identifiable mainshock. These clusters span a 30-km-long segment and coincide with transient deformation recorded at the end of 2013.</p>
Growth-related formation mechanism of I3-type basal stacking fault in epitaxially grown hexagonal Ge-2H
<p>The hexagonal-2H crystal phase of Ge recently emerged as a promising direct bandgap semiconductor in the mid-infrared range providing new prospects of additional opto-electronic functionalities of group-IV semiconductors (Ge and SiGe). The controlled synthesis of such hexagonal (2H) Ge phase is a challenge that can be overcome by using wurtzite GaAs nanowires as a template. However, depending on growth conditions, unusual basal stacking faults (BSFs) of I<sub>3</sub>-type are formed in the metastable 2H structure. The growth of such core/shell heterostructures is observed <em>in situ</em> and in real-time by means of environmental transmission electron microscopy using chemical vapour deposition. The observations provide direct evidence of a step-flow growth of Ge-2H epilayers and reveal the growth-related formation of I<sub>3</sub>-BSF during unstable growth. Their formation conditions are dynamically investigated. Through these <em>in situ</em> observations, we can propose a scenario for the nucleation of I<sub>3</sub>-type BSFs that is likely valid for any metastable hexagonal 2H or wurtzite structures grown on m-plane substrates. Conditions are identified to avoid their formation for perfect crystalline synthesis of SiGe-2H.</p> <p>This data set contains all the processed supporting videos of in-situ TEM observations .</p> <p> </p>

Geometric Control on Seismic Rupture and Earthquake Sequence along the Yingxiu-Beichuan Fault with Implications for the 2008 Wenchuan Earthquak
<p>A 65000 years seismic sequence is numerical simulated using TriBIE on the unplanar fault plane with variation normal stress. The code is now available in an open-source Git-hub project, <a href="https://github.com/daisy20170101/TriBIE/tree/normal_stress_variation">https://github.com/daisy20170101/TriBIE/tree/normal_stress_variation</a>.</p> <p>The modeling will output the bianary format files of normal stress, fault slip velocity, shear stress, slip during the interseismic loading and coseismic rupture stage, respectively. Since it is impossible to output the data at every time step, especially for the large-scale fault model. Thus, during the interseismic loading, we set a constant time interval to output data and the t-inter-***.dat file will record every time, when the data is outputted. During coseimic rupture, t-cos-**.dat file records time of outputing data. So, the size of t-inter-**.dat and t-cos-**.dat file is the number of outputting steps.The fault plane is discretized into 3,1440 elements and the simulation is carried out by parallel computing on 6 servers with 120 CPUs . Each CPU will dispose data of 262 elements. </p> <p> </p> <p> </p> <p> </p> <p> </p>
