Given the deficiency of recorded strong ground-motion data, it is important to understand the effects of earthquake rupture processes on near-source ground-motion characteristics and to develop physics-based ground-motion simulation methods for advan

Publikováno v: Intelligent Systems, Control and Automation: Science and Engineering ISBN: 9783030707866

In this paper, a new deep learning approach based on native parsimony using the topological gradient method is introduced. This approach reduces the number of links to be identified by the learning process by several orders of magnitude and consequen

Rupture analysis of the 2020 Petrinja earthquake based on seismological observations

Autor: Mathieu Causse

Here, I use seismological observations (~70 broadband stations at distances between 100 and 400 km from the source) to characterize the rupture properties of the Petrinja mainshock (Mw 6.4). First, I perform a spectral analysis of the P-waves to comp

Although moderate‐size earthquakes are poorly studied by lack of near‐fault observations, they can provide key information about larger damaging earthquakes. Here we propose a new approach, inspired by double‐difference relocation, that uses hi

Bayesian rupture imaging in a complex medium: The 29 May 2012 Emilia, Northern Italy, earthquake

Publikováno v: Geophysical Research Letters. 44:7783-7792

We develop a new approach to image earthquake rupture from strong motion data. We use a large data set of aftershock waveforms, interpolated over the seismic fault to obtain Green's function approximations. Next we deploy a Bayesian inversion method
