Seismic Ray Theory
, 2001
"... Introduction T he propagation of seismic body waves in complex, laterally varying 3D layered structures is a complicated process. Analytical solutions of the elastodynamic equations for such types of media are not known. The most common approaches to the investigation of seismic wavefields in such ..."

and sufficiently smooth media only. Similarly, certain properties of vectorial complexvalued amplitudes of seismic body waves can be derived using energy concepts, particularly using the expressions for the energy flux. Such an approach is again very useful for intuitive physical understanding of the amplitude
Control of Seismic Energy Partitioning of Bridge Piers with Sliding Rubber Bearing
"... Base isolation bearings have many good properties for seismic protection of bridges. Recently a new sliding rubber bearing was developed, which has both characteristics of sliding and rubber bearings. When we install these seismic isolation systems, reasonable inelastic design method is required. Bu ..."

. But since the conventional inelastic design method takes into account only bridge piers, it is hard to design seismic isolators which can cope with the interaction between seismic isolators and bridge piers. The purpose of this study is to understand the relationship between the seismic isolation systems
submitted to Geophys. J. Int. Energy partition of seismic coda waves in layered media: theory and application to Pinyon Flats Observatory
, 2008
"... We have studied the partition of shear, compressional and kinetic energies in the coda of ten earthquakes recorded on a dense array, located at Pinyon Flats Observatory (PFO), California. Deformation energies are estimated by measuring finite differences of the wavefield components. We have thorough ..."

Moment Partitioning for InjectionInduced Seismicity: Case Studies & Insights from Numerical Modeling
"... ABSTRACT In order to understand and mitigate felt seismicity induced by fluid injection activities such as Enhanced Geothermal Systems, it is important to know what controls the seismic response to the injection of a certain volume. A recent study proposed an upper bound to induced magnitudes that ..."

A theorem concerning twisted and untwisted partition
, 2009
"... In order to get a clue to understanding the volumedependence of vortex free energy (which is defined as the ratio of the twisted against the untwisted partition function), we investigate the relation between vortex free energies defined on lattices of different sizes. An equality is derived through ..."

SeismoAcoustic Energy Partitioning at NearSource and Local Distances from the 2011 Sayarim Explosions in the Negev Desert, Israel
, 2011
"... the Negev Desert, Israel, provide a unique dataset to study seismic and acoustic partitioning for surface sources at nearsource and local distances. We present an analysis of the seismic and overpressure/acoustic signals generated from two explosions, which included 10,240 and 102,080 kg of mainly ..."

Z.: Partition function expansion on regiongraphs and messagepassing
, 1200
"... Abstract. Disordered and frustrated graphical systems are ubiquitous in physics, biology, and information science. For models on complete graphs or random graphs, deep understanding has been achieved through the meanfield replica and cavity methods. But finitedimensional ‘real ’ systems persist to ..."

GJI Seismology Open dissipative seismic systems and ensembles of strong earthquakes: energy balance and entropy funnels
"... A concept of seismic system (SS), which is responsible for the preparation of an ensemble of strong earthquakes, is considered as an open dissipative system exchanging energy and entropy with the environment. Open dissipative SS allow one to describe the equilibrium and nonequilibrium states of SS, ..."

Several new seismic parameters (‘seismic temperature’, ‘seismic time’, dissipation function, efficiency, inelastic energy, dynamical probability) are defined and proposed for better understanding and describing
Waveequation inversion prestack Hessian
