Three‐dimensional Moho topography in Italy: New constraints from receiver functions and controlled source seismology

[1] In complex tectonics regions, seismological, geophysical, and geodynamic modeling require accurate definition of the Moho geometry. Various active and passive seismic experiments performed in the central Mediterranean region revealed local information on the Moho depth, in some cases used to produce interpolated maps. In this paper, we present a new and original map of the 3‐D Moho geometry...

Computational Challenges in Seismology

Seismology and engineering seismology have been dramatically affected by the emergence of high-performance computing. A recent report by the National Research Council's Committee on Seismology (NRC, 1996) is entirely devoted to surveying the status and potential of high-performance computing activities in this field. Here we summarize several applications and focus on one particular problem, th...

Mathematical Questions in Seismology

Seismologists, like mathematicians, are accustomed to dividing their subject into a pure and an applied branch. The desirability of such division is underlined by the manner in which non-seismologists frequently approach the subject. I t is too often taken for granted that, because an earthquake is a motion of the ground, seismology must be chiefly concerned with the detailed analysis of that m...

GPS seismology

GPS seismology uses convential geodetic models to analyze GPS data at high sampling rates, such as 1 Hz. GPS seismology results are shown for the Denali, San Simeon, Tokachi-oki, and Chuetsu earthquakes. Records for these earthquakes indicate that GPS is an excellent instrument for measuring large displacements near earthquake ruptures. GPS systems can be improved for seismic applications if th...
