Seismic shear waves as Foucault pendulum
Earth’s rotation causes splitting of normal modes. Wave fronts and rays are, however, not affected by Earth’s rotation, as we show theoretically and with observations made with USArray. We derive that the Coriolis force causes a small transverse component for P waves and a small longitudinal component for S waves. More importantly, Earth’s rotation leads to a slow rotation of the transverse pol...
متن کاملElastic waves as a Foucault pendulum?
The rotation of the Earth leads to a change in the equation of motion because of the Coriolis force. We study how Earth’s rotation affects elastic wave propagation. We show that the Coriolis force does not deflect seismic rays because the medium that carries the waves moves with Earth’s rotation. However, Earth’s rotation causes a weak traverse component of P-waves and a weak longitudinal compo...
متن کاملSeismic Rehabilitation of Liquid Storage Tanks using Friction Pendulum Base Isolation subjected to the Near-Fault Ground Motions
Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...
متن کاملShear-wave imaging from traffic noise using seismic interferometry by cross-coherence
We apply seismic interferometry to traffic noise to retrieve both body waves and surface waves. Our preferred algorithm in the presence of highly variable and strong additive random noise uses cross-coherence, which uses normalization by the spectral amplitude of each of the traces, rather than cross-correlation or deconvolution. This normalization suppresses the influence of additive noise and...
متن کاملInvestigation of the strength and trend of seismic anisotropy beneath the Zagros collision zone
The Zagros collision zone is known as an active tectonic zone that represents the tectonic boundary between the Eurasian and Arabian plates. A popular strategy for gaining insight into the upper mantle processes is to examine the splitting of seismic shear waves and interpret them in terms of upper mantle anisotropy and deformation. Core phases SK(K)S from over 278 earthquakes (MW ≥ ...
