Flexible Spatio-Temporal Hawkes Process Models for Earthquake Occurrences
Junhyeon Kwon, Yingcai Zheng, Mikyoung Jun
Hawkes process is one of the most commonly used models for investigating the self-exciting nature of earthquake occurrences. However, seismicity patterns have complicated character…
Simultaneous inversion of layered velocity and density profiles using Direct Waveform Inversion (DWI): 1D case
Zhonghan Liu, Yingcai Zheng, Hua-Wei Zhou
We propose and test the Direct Waveform Inversion (DWI) scheme to simultaneously invert for layered velocity and density profiles, using reflection seismic waveforms recorded on th…
A Numerical Study on the Effects of Heterogeneity, Anisotropy, and Station Coverage on the Compensated Linear Vector Dipole Component of Deep Earthquake Moment Tensors
Jiaxuan Li, Yingcai Zheng, Xinding Fang
The moment tensors of a large portion of deep earthquakes show apparent non-double-couple (non-DC) components. Previously, the observed apparent non-DC values in deep earthquakes h…
Stochastic inversion of Gaussian random media using transverse coherence functions for reflected waves
Hao Hu, Yingcai Zheng
The transverse coherence functions (TCFs) of phase and amplitude fluctuations of a seismic wave are powerful to estimate the spatial distribution, length scales, and strength of ra…
AstroSeis -- A 3D Boundary element modeling code for seismic wavefields in irregular asteroids and bodies
Yuan Tian, Yingcai Zheng
We developed a 3-D elastic Boundary Element Method (BEM) computer code, called AstroSeis, to model seismic wavefields in a body with an arbitrary shape, such as an asteroid. Beside…
Rapid falling of an orbiting moon to its parent planet due to tidal-seismic resonance
Yuan Tian, Yingcai Zheng
Tidal force plays an important role in the evolution of the planet-moon system. The tidal force of a moon can excite seismic waves in the planet it is orbiting. A tidal-seismic res…
