Focal mechanism of Luding M 6.8 earthquake, September 2022 and analysis of the loading role of the tectonic stress on the seismogenic fault

open access: yesEarthquake Research Advances, 2023
To reveal the seismogenic mechanism of the Luding earthquake, we employed the 118 China Seismic Network stations to collect the P-wave polarity data from each station, which was then used in the P-wave first motion approach to calculate the focal ...

Time-Frequency Analysis of Systems with Changing Dynamic Properties [PDF]

open access: yes, 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

Stress drops and radiated energies of aftershocks of the 1994 Northridge, California, earthquake [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2003
We study stress levels and radiated energy to infer the rupture characteristics and scaling relationships of aftershocks and other southern California earthquakes. We use empirical Green functions to obtain source time functions for 47 of the larger (M ≥ 4.0) aftershocks of the 1994 Northridge, California earthquake (M6.7).

The Relationship of Small Earthquakes to Strain Accumulation Along Major Faults in Southern California [PDF]

open access: yes, 1983
Fault-plane solutions for recent small (ML ≤ 4.6) earthquakes in the central Transverse Ranges, California, were determined using an azimuthally-varying crustal model.

Earth’s gravity ― the reason of earthquakes

open access: yesГеофизический журнал, 2019
In the paper, an attempt has been made to describe seismic processes by means of classical mechanics. Dynamic parameters such as energy, impulse, and forces that determine the movement of masses are estimated.

Estimating Rupture Front of Large Earthquakes Using a Novel Multi-Array Back-Projection Method

open access: yesFrontiers in Earth Science, 2021
A ruptured front obtained from high-frequency energy radiation is the key to understand the complex source. It is commonly observed that rupture fronts derived from different arrays often show some variations due to the obvious difference of the ...
