Overview over the contents of this folder:
3mHz.pdf (680 kB): A publication by Zürn and Wielandt
presenting a physical explanation for the minimum of
vertical seismic noise near 3 mHz.
NonplaneWaves_Summary.doc (26 kB). Summary of the publication
on nonplane waves, with a link to the scan of the full text.
NonplaneWaves.pdf (700 kB): A scan of the publication
"Propagation and structural interpretatioin of nonplane
waves", 1993. This paper investigates the relationship
between two conceptually different notions of phase
velocity, namely the "structural" phase-velocity parameter
in the wave equation and the "dynamic" phase velocity of a
wave.
SurfaceWaves_Summary.doc. Summary of a note on seismic surface
waves over 3-d structures, with a link to the postscript
version of the full text.
surface-waves.ps (1620 kB): A note on the interpretation of
seismic surface waves over 3-d structures, by Friederich,
Hunzinger and Wielandt. A numerical experiment exploring
the difference between "structural" and "dynamic" phase
velocities.
volumesource1.dvi (23 kB), volumesource1.ps (130 kB):
Basics of the volume-source model and its application
in volcano seismology. Explains the nontrivial but simple
relationship between the time-dependent volume of an
expansive source and the seismic signal. Manuscript of
a workshop presentation (Santorin, 1999)
Volumesource2.dvi (27 kB), Volumesource2.ps (130 kB):
A theoretical discussion of the relationship between
seismic moment and source volume. What does the isotropic
part of the moment tensor really say about the physical
source? Not what most seismologists believe. Unpublished
manuscript, 13 pages.
