Investigation of historical earthquake by seismic wave propagation simulation: Source parameters of the 1887 M6.3 Ligurian, north-western Italy, earthquake

RÉSUMÉ. Les simulations numériques haute performance de la propagation des ondes sismiques de la source à la surface du sol sont un outil puissant pour l’étude d’un séisme. Comme la sismologie moderne basée sur les observations instrumentales n’existe que depuis quelques décennies, la simulation numérique est essentielle pour l’étude des séismes historiques ou l’estimation de futurs séismes pou...

Seismic source modeling by clustering earthquakes and predicting earthquake magnitudes

Seismic sources are currently generated manually by experts, a process which is not efficient as the size of historical earthquake databases is growing. However, large historical earthquake databases provide an opportunity to generate seismic sources through data mining techniques. In this paper, we propose hierarchical clustering of historical earthquakes for generating seismic sources automat...

Systematic comparisons of earthquake source models determined using InSAR and seismic data

a r t i c l e i n f o Robust earthquake source parameters (e.g., location, seismic moment, fault geometry) are essential for reliable seismic hazard assessment and the investigation of large-scale tectonics. They are routinely estimated using a variety of data and techniques, such as seismic data and, more recently, Interferometric Synthetic Aperture Radar (InSAR). Comparisons between these two...

Application of Seismic Array Processing to Earthquake Early Warning

Earthquake early warning (EEW) systems that issue warnings prior to the arrival of strong shaking are essential in mitigating earthquake hazard. Currently operating EEW systems work on point-source assumptions and are of limited effectiveness for large events, for which ignoring finite-source effects result in magnitude underestimation. Here, we explore the concept of characterizing rupture dim...
