The Doppler effect induced by earthquakes: A case study of the Wenchuan MS8.0 earthquake
Geodesy and Geodynamics, 2022 Seismologists have found that the first arrival frequencies of P waves at different seismic stations have different widths, that is, different periods or frequencies, and they think that this phenomenon can be used to identify whether a Doppler effect is

Evaluation of MCC seismic response according to the frequency contents through the shake table test
Nuclear Engineering and Technology, 2021 Damage to nuclear power plants causes human casualties and environmental disasters. There are electrical facilities that control safety-related devices in nuclear power plants, and seismic performance is required for them.

Modeling Low‐Frequency Earthquake Recurrence Patterns [PDF]
Geophysical Research Letters, 2017 AbstractTectonic tremor and low‐frequency earthquakes (LFE) have been identified globally, but the physical mechanisms responsible for different types of LFE recurrence patterns are still elusive. Here we use a brittle ductile friction model to study the frictional conditions leading to different LFE recurrence patterns observed in central California ...

Time-Frequency Analysis of Systems with Changing Dynamic Properties [PDF]
, 2006 The Wigner-Ville Distribution, and related refinements, represent a class of advanced time-frequency analysis tools that are distinguished from Fourier and wavelet methods by an increase in resolution in the time frequency plane. Time-frequency analysis

Entropy, energy, and proximity to criticality in global earthquake populations [PDF]
, 2002 We examine the question of proximity of the global earthquake population to the critical point characterised by the energy E and entropy S based on annual frequency data from the Harvard CMT catalogue.

Earthquake Source Characterization Using 3D Numerical Modeling [PDF]
, 2007 To understand the physics of earthquakes, it is important to know what happens during individual events. Dissembling the information about the source process from the recorded seismograms is a difficult and non-unique process, as there are severe trade ...

Dynamic analysis of shear building structure using wavelet transform [PDF]
Numerical Methods in Civil Engineering, 2018 Dynamic analysis of shear building structures (SBS) is achieved using fast wavelet transform (FWT). The loads are considered as acceleration of earthquake record. for the analysis, A time history dynamic analysis is carried out.

A method for minimising of low frequency and unwrapping artefacts from interferometric calculations [PDF]
, 2006 On 7 September 1999 a magnitude MW55.9 earthquake occurred in the Athens area of Greece producing a subsidence of 6–7 cm detected by radar interferometry.
