This book was released on 2012-01-11 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is remarkable for the wide range of the techniques and observations used and for its insights, which cross several disciplines. It begins by solving a famous puzzle of the ancient world, which is what was responsible for the tsunami that destroyed settlements in the eastern Mediterranean in 365 AD. By radiocarbon dating of preserved marine organisms, Shaw demonstrates that the whole of western Crete was lifted out of the sea by up to 10 meters in a massive earthquake at that time, which occured on a previously unknown fault. The author shows that the resulting tsunami would have the characteristics described by ancient writers, and uses modern GPS measurements and coastline geomorphology to show that the strain build-up near Crete requires such a tsunami-earthquake about every 6.000 years - a major insight into Mediterranean tsunami hazard. A detailed seismological study of earthquakes in the Cretan arc over the last 50 years reveals other important features of its behaviour that were previously unknown. Finally, she provides fundamental insights into the limitations of radiocarbon dating marine organisms, relating to how they secrete carbon into their skeletons. The thesis resulted in three major papers in top journals.

Available in PDF, EPUB and Kindle. Book excerpt: Hardly a week passes without our learning of natural geologic disaster somewhere in the world, be it a volcanic eruption, landslide, or destructive earthquake. The prominent public notice given to such events is not only the result of better communications, but also results from the increased impact of these events on a growing human population. In recent years, the population has increased greatly in regions of active tectonics. Northern India and the surrounding areas are prime examples. The consequence is that people and their man-made structures are concentrated close to active faults and steep, landslide-prone terrains. In just the past several years, even moderate earthquakes with seismic magnitudes less than 6. 5 have killed as many as 20,000 people precisely because these earthquakes occurred directly beneath population centres in central India. The greater Himalayan region, including the Ganges Plain, is a prime example of the coexistence of a pronounced geological hazard with a growing human population. Due in part to the spectacular topography, the region has long attracted scientific investigations, and may be considered as the birthplace of modern studies of earthquake hazards. R. D. Oldham (1858-1936) of the Geological Survey of India played a prominent role in the development of modern studies of historical seismicity, active faulting and seismic wave analysis. Oldham published extensively on the earthquakes and the geology of India, including his report entitled Catalogue of Indian earthquakes from the earliest time to the end of A. D. 1869 (Mem. Geol. Surv."

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a detailed seismotectonic investigation of the Himalayan region and the Tibetan plateau as part of project HiCLIMB to explore the state of stress and the kinematics of the world?s largest continental collision zone. Using full regional waveforms for moment tensor inversion, source parameters for 107 earthquakes were determined with moment-magnitudes (Mw) ranging from 3.5 to 6.3. The significant decrease in magnitude threshold with respect to previous studies was accomplished through the usage of broadband data from the HiCLIMB, HIMNT, and Bhutan temporary networks. Combining the results from this study with previously published earthquake source parameters, the investigation focuses on three topics: (1) Deformation along the front of the Himalayan arc associated with the Main Himalayan Thrust (2) Extension in the southern Tibetan plateau, and (3) Location and stress orientation of intermediate-depth earthquakes. Thrust event epicenters along the Himalayan front closely coincide with the 3500 m topography contour. These earthquakes can be associated with elastic strain accumulation near the lower tip of the locked part of the MHT due to tectonic loading from its creeping down-dip extension. Centroid depths and nodal plane dips of these thrust events are inconsistent with slip merely on the main detachment and indicate significant deformation in the vicinity of the MHT. Especially in far western Nepal, nodal plane dips are systematically steeper and slip during these events might play a role in the formation of asperities and barriers on the detachment surface. The P-axes azimuths of the thrust events along the Himalayan arc deviate considerably from a mere circular geometry. Spatial filtering of the regional topography reveals that slip of events in the footwall as well as the hanging wall aligns perpendicular to the mountain range on a 50 km wavelength scale. The topography-perpendicular alignment of the slip direction on planes with significant inclination suggests that these thrust events contribute considerably to the mountain building process and to the formation of the local shape of the arc. Deformation on the southern Tibetan plateau is dominated by shallow normal faulting in the upper 15 km of the crust. The extensional direction, while generally trending east-west, shows an apparent transition from arc parallel in the Tethyan Himalaya to northward convex in the southern Lhasa terrane. North of about N31ð, deformation changes to strike-slip prevalence. The locations of changes in faulting patterns coincide with changes in geometry of the underthrusting Indian crust revealed by receiver function images. This correlation indicates a significant influence of basal traction on shallow crustal faulting processes. This study provides additional evidence that most intermediate-depth seismicity occurs beneath the Moho, signifying a strong upper mantle. Faulting in the upper mantle is dominated by strike-slip faulting with northerly trending P-axes. The maximum horizontal compressive stress axes of mantle earthquakes align with the direction of the India-Eurasia convergence and imply a relation of this deformation to the subduction process.

This book was released on 2015 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The north component of gravity and gravity gradient changes from the Gravity Recovery And Climate Experiment (GRACE) are used to study the coseismic gravity change for five earthquakes over the last decade: the 2004 Sumatra-Andaman earthquake, the 2007 Bengkulu earthquake, the 2010 Maule, Chile earthquake, the 2011 Tohoku earthquake, and the 2012 Indian Ocean earthquakes. We demonstrate the advantage of these north components to reduce north-south stripes and preserve higher spatial resolution signal in GRACE Level 2 (L2) monthly Stokes Coefficients data products. By using the high spherical harmonic degree (up to degree 96) data products and the innovative GRACE data processing approach developed in this study, the retrieved gravity change is up to - 34±1.4 μGal for the 2004 Sumatra and 2005 Nias earthquakes, which is by far the highest coseismic signal retrieved among published studies. Our study reveals the detectability of earthquakes as small as Mw 8.5 (i.e., the 2007 Bengkulu earthquake) from GRACE data. The localized spectral analysis is applied as an efficient method to determine the practical spherical harmonic truncation degree leading to acceptable signal-to-noise ratio, and to evaluate the noise level for each component of gravity and gravity gradient change of the seismic deformations.
