Lithospheric delamination beneath the southern Puna plateau resolved by local earthquake tomography
Jing Chen, Sofia-Katerina Kufner, Xiaohui Yuan +5
We present a local earthquake tomography to illuminate the crustal and uppermost mantle structure beneath the southern Puna plateau and to test the delamination hypothesis. Vp and…
The Wasserstein-Fisher-Rao metric for waveform based earthquake location
D. T. Zhou, J. Chen, H. Wu +2
In our previous work [Chen el al., J. Comput. Phys., 373(2018)], the quadratic Wasserstein metric is successfully applied to the earthquake location problem. The actual earthquake…
The quadratic Wasserstein metric for earthquake location
Jing Chen, Yifan Chen, Hao Wu +1
In [Engquist et al., Commun. Math. Sci., 14(2016)], the Wasserstein metric was successfully introduced to the full waveform inversion. We apply this method to the earthquake locati…
The auxiliary function method for waveform based earthquake location
Hao Wu, Jing Chen, Hao Jing +2
This paper introduces the auxiliary function method (AFM), a novel, fast and simple approach for waveform based earthquake location. From any initial hypocenter and origin time, we…
A new earthquake location method based on the waveform inversion
Hao Wu, Jing Chen, Xueyuan Huang +1
In this paper, a new earthquake location method based on the waveform inversion is proposed. As is known to all, the waveform misfit function is very sensitive to the phase shift b…
