Impact - generated seismic signals on Mars
Meteorite impacts will be a key seismic source for probing Mars’ interior during the InSight mission. Maximising data exploitation requires a good understanding of impact-generated seismic ground motions (waves), which has been limited by a lack of observational data and the practical difficulty of replicating relevant martian impact conditions in experiments. The aim of this PhD project is to ...
متن کاملUniversality of the Seismic Moment-frequency Relation
We analyze the seismic moment-frequency relation in various depth ranges and for different seismic regions, using Flinn-Engdahl’s regionalization of global seismicity. Three earthquake lists of centroid-moment tensor data have been used: the Harvard catalog, the USGS catalog, and the HUANG et al. (1997) catalog of deep earthquakes. The results confirm the universality of the b-values and the ma...
متن کاملSeismic behavior of drilled beam section in moment connections
Abstract: Reduced Beam Section (RBS) and Drilled Beam Section (DBS) are seismic moment resistant frame connections, introduced after 1994 Northridge earthquake. RBS connection has been tested under cyclic loading and showed acceptable performance. In this paper, seismic behavior of Drilled Beam Section (DBS) connection is studied numerically using finite element method. A drilled beam section ...
متن کاملParametrization of general seismic potency and moment tensors for source inversion of seismic waveform data
S U M M A R Y We decompose a general seismic potency tensor into isotropic tensor, double-couple tensor and compensated linear vector dipole using the eigenvectors and eigenvalues of the full tensor. Two dimensionless parameters are used to quantify the size of the isotropic and compensated linear vector dipole components. The parameters have well-defined finite ranges and are suited for non-li...
متن کاملThe Seismic Effect of Impacts on Asteroid Surface Morphology: Three-
Introduction: In recent years, spacecraft observations of 'medium-sized' asteroids 951 Gaspra, 243 Ida, 253 Mathilde, and most importantly 433 Eros have shown the overriding dominance of impact processes with regard to the structure and appearance of these irregular bodies. In a previous work [1], I investigated the relatively unexplored area of seismic shaking as a cause for the downslope moti...
