Distributed communication systems have gained a substantial importance over the past years with a large set of examples of systems that are present in our everyday life. The heterogeneity of applications and application domains speaks for the complexity of such systems and the challenges that developers are faced with. The focus of this dissertation is on the development of applications for dis...

[1] We investigate temporal variations in the polarization of surface waves determined using ambient seismic noise cross‐correlations between station pairs at the time of the Mw 6.0 Parkfield earthquake of September 28, 2004. We use data recorded by the High Resolution Seismic Network’s 3‐component seismometers located along the San Andreas Fault. Our results show strong variations in azimuthal...

We report that during the two devastating 1999 earthquakes in Turkey, rupture propagated over a large part of the nearly 200km long fault zone at supershear speed approaching 5km/s. We present observations and modeling which confirm the original inference of supershear rupture during the Izmit earthquake and we show that supershear upture also occurred during the Diizce earthquake. We show that...

Immediately following the 1966 Parkfield earthquake a continuing program of fault displacement measurements was undertaken, and several types of instruments were installed in the fault zone to monitor ground motion. In the year subsequent to the earthquake a maximum of at least 20 cm of displacement occurred on a 30 km section of the San Andreas fault, which far exceeded the surfidal displaceme...

In this study, we extract earthquake co-occurrence patterns for investigating mechanical interactions in the affected areas. To extract seismic patterns, both co-occurrence among seismic events in the event sequence and distances between the hypocenters to find hot spots must be considered. Most previous researches, however, have considered only one of these aspects. In contrast, we utilized co...

The 1985 prediction of a characteristic magnitude 6 Parkfield earthquake was unsuccessful, since no significant event occurred in the 95% time window (1985–1993) anywhere near Parkfield. The magnitude 6 earthquake near Parkfield in 2004 failed to satisfy the prediction not just because it was late; it also differed in character from the 1985 prediction and was expectable according to a simple n...

For a decade, the U.S. Geological Survey has used the Parkfield Earthquake Prediction Experiment scenario document to estimate the probability that earthquakes observed on the San Andreas fault near Parkfield will turn out to be foreshocks followed by the expected magnitude 6 mainshock. During this time, we have learned much about the seismogenic process at Parkfield, about the long-term probab...

Field investigations and interpretations of high-resolution remote sensing images reveal geomorphic features of cumulative offsets and deflections of Holocene streams and gullies along the western 450-km segment of the Kunlun fault which triggered the 2001 Mw 7.8 Kunlun earthquake in the northern Tibetan Plateau. The streams and gullies developed on Holocene alluvial fans are sinistrally displa...

We use radar amplitude images acquired by the ENVISAT/ASAR sensor to measure the coseismic deformation of the 8 October 2005 Kashmir earthquake. We use the offset images to constrain the fault trace, which is in good agreement with the field investigations and the aftershock distribution. We infer a complete 3-D surface displacement field of the Kashmir earthquake using the offset measurements ...

The seismicity of southern Spain is characterized by low-to-moderate earthquake activity (magnitudes <5.5) related to the convergence of the African and Eurasian plates. The detailed structure of this complex plate boundary is not well understood and the study of faulting parameters and depths of the small-to-moderate-size events can contribute much to our understanding of the regional stresses...
