Earthquake hazard assessments and rupture forecasts are based on the potential length of seismic rupture and whether or not slip is arrested at fault segment boundaries. Such forecasts do not generally consider that one earthquake can trigger a second large event, near-instantaneously, at distances greater than a few kilometres. Here we present a geodetic and seismological analysis of a magnitu...

in this study, the 2005 dahuieh (zarand) locally recorded aftershock sequence has been analyzed. having the distribution of aftershocks and the source extension, a w-e trending near vertical faulting with an extension of about 15-20 km could be estimated. the rupture causing the powerful dahuieh earthquake apparently initiated in the modified epicentric area and propagated unilaterally towards ...

It is expected that MPLS-based recovery could become a viable option for obtaining faster restoration than layer 3 rerouting. To deliver reliable service, however, MPLS requires a set of procedures to provide protection for the traffic carried on the label switched paths. In this article we propose a path protection mechanism that is simple, scalable, fast, and efficient. We describe in detail ...

As software systems mature, there is the danger that not only code decays, but software architecture as well. We adapt a reverse architecting technique to defect reports of a series of releases. Relationships among system components are identified based on whether they are involved in the same defect report, and for how many defect reports this occurs. There are degrees of fault-coupling betwee...

Contractional deformation is common along transform plate margins where motion oblique to the boundary. While faults that accommodate this are often inferred be subsidiary main boundary fault, we typically lack direct geometric or kinematic information. Here investigate timing of faulting relative changes in orientation North American-Pacific Coeval with development an segment (i.e., “Big Bend”...

Many estimates of seismic risk depend crucially on how well the date of faulting events can be determined from the stratigraphic position of fault strands exposed in exploratory trenches. However, fault strands cut by trenches may seem to die out where they are in fact only poorly expressed, or they may actually die out. Such ambiguity can lead to misinterpretation of the time of the most recen...
