A summary of seismic activities in and around China in 2021

Earthquake Research Advances, 2022
In this article, we review the general characteristics of seismicity in and around China and the overall statistics of earthquake damage in 2021, focusing on several significant events and related scientific topics.

Magnitude-Dependent Omori Law: Empirical Study and Theory

, 2004
We propose a new physically-based ``multifractal stress activation'' model of earthquake interaction and triggering based on two simple ingredients: (i) a seismic rupture results from activated processes giving an exponential dependence on the local ...

Kinetic aspects of foreshock cavities [PDF]

Geophysical Research Letters, 2006
We have investigated the kinetic signatures within, and at the edges of, a foreshock cavity. Such cavities are believed to be formed when an isolated collection of interplanetary magnetic field lines connect to quasi‐parallel regions of the Earth's bow shock, allowing energetic ions to flow upstream and excavate a local cavity.

Are Aftershocks of Large Californian Earthquakes Diffusing? [PDF]

, 2003
We analyze 21 aftershock sequences of California to test for evidence of space-time diffusion. Aftershock diffusion may result from stress diffusion and is also predicted by any mechanism of stress weakening.

Apparent Clustering and Apparent Background Earthquakes Biased by Undetected Seismicity

, 2005
In models of triggered seismicity and in their inversion with empirical data, the detection threshold m_d is commonly equated to the magnitude m_0 of the smallest triggering earthquake. This unjustified assumption neglects the possibility of shocks below

Oxygen foreshock of Mars

Planetary and Space Science, 2015
AbstractMars Express (MEX) has operated for more than 10 years in the environment of Mars, providing solar wind ion observations from the Analyzer of Space Plasmas and Energetic Atoms experiment's Ion Mass Analyser (IMA). On 21 September 2008, MEX/IMA detected foreshock-like discrete distributions of oxygen ions at around 1keV in the solar wind ...

Earthquake rupture properties of the 2016 Kumamoto earthquake foreshocks (Mj 6.5 and Mj 6.4) revealed by conventional and multiple-aperture InSAR

Earth, Planets and Space, 2017
By applying conventional cross-track InSAR and multiple-aperture InSAR (MAI) techniques with ALOS-2 SAR data to foreshocks of the 2016 Kumamoto earthquake, ground displacement fields in range (line-of-sight) and azimuth components have been successfully ...

Nonlinear Waves in the Terrestrial Quasiparallel Foreshock [PDF]

Physical Review Letters, 2016
We study the applicability of the derivative nonlinear Schr dinger (DNLS) equation, for the evolution of high frequency nonlinear waves, observed at the foreshock region of the terrestrial quasi-parallel bow shock. The use of a pseudo-potential is elucidated and, in particular, the importance of canonical representation in the correct interpretation ...

A phase coherence approach to identifying co-located earthquakes and tremor [PDF]

, 2017
We present and use a phase coherence approach to identify seismic signals that have similar path effects but different source time functions: co-located earthquakes and tremor.

Earthquakes: from chemical alteration to mechanical rupture

, 1998
In the standard rebound theory of earthquakes, elastic deformation energy is progressively stored in the crust until a threshold is reached at which it is suddenly released in an earthquake.
