Earthquakes, groundwater and surface deformation : exploring the poroelastic response to megathrust earthquakes
… the poroelastic effects of large subduction zone earthquakes using numerical models and a variety of datasets with the overarching goal of beginning to deconvolve post-seismic geodetic deformation signals -- while exploring other interesting phenomena involving the poroelastic response to …

Investigations of Anomalous Earthquakes at Active Volcanoes
… unrest and the occurrence of moderate-to-large earthquakes with a specific type of focal mechanism. Vertical compensated-linear-vector-dipole (vertical-CLVD) earthquakes have vertical pressure or tension axes and seismic radiation patterns that are inconsistent with the double-couple model of …

The Relationship Between Intraplate Earthquakes and Temperature
… is used to constrain the focal depths of 18 earthquakes, which are used along with published teleseismic and local-event studies to examine the seismogenic thickness (T<sub>s</sub>) in the Baikal region. All sets of earthquake data show that the mantle in this region is not a significant …

Space-time rupture properties of large earthquakes
Slow earthquakes have been hypothesized to be compound events, i.e. comprised of both an ordinary earthquake and a smooth moment-release transient of longer duration. Low-frequency normal-mode based studies which support the compound event hypothesis have suggested that low-frequency source-spectra …

Relocation of Eastern Tennessee Earthquakes Using hypoDD
… to relocate a data set of approximately 1000 earthquakes in the eastern Tennessee seismic zone (ETSZ), using a recently developed velocity model. The double difference algorithm is used to calculate accurate relative hypocenter locations by removing the effects of un-modeled velocity …

Mutual pounding of structures during strong earthquakes
… other during strong ground shaking caused by earthquakes. The main objective of this study is to examine the problem of mutual structural pounding to identify its effect on structures and then propose solutions to mitigate its effects. Mutual pounding of structural systems with varying mass, …

Predicting the Dynamics of Injection-Induced Earthquakes
… of fluids at depth are known to trigger earthquakes. Fluid injection increases the internal pore pressure of the host rock, which in turn reduces the effective stress and frictional resistance of faults that maintain the fractured rock system in a state of mechanical equilibrium. Under …

Liquefaction Triggering Model for Subduction Zone Earthquakes
… lead to inaccurate results for megathrust earthquakes in subduction interfaces. To overcome this drawback and to achieve better prediction of liquefaction cases in subduction zones, this research intends to develop new empirical models that could be used for the prediction of liquefaction …

Seismic fragility of buildings damaged by past earthquakes
… ignoring the possibility of having multiple earthquakes during the service life of the structure. However, considering the relatively high probability of multiple earthquakes (including main shock-aftershock sequence) and the reality that some buildings might not satisfy the previous seismic …
