FMT package runs under Linux operational
system. It includes following components: Data Base, DbCreator, FTAN , and MomTens
Data Base is a
package of programs
designed by Daniel Quinlan (IRIS corporation(
http://www.passcal.nmt.edu/software/datascope/datascope.html
).
Practically all the program components described on these
pages
are using this package.
DbCreator is a program for creating data
base of seismograms for further processing by
FTAN program.
Frequency-time analysis program
FTAN
performs floating filtering of seismograms. It is a
Colorado University product designed by Prof. A. L. Levshin,
Prof.
M. Ritzwoller , and their assistants and students.
Program FTAN
works under control of "Ftan
control
panel" program named ftan. Using ftan
program you
define input data, processing parameters, start FTAN as
external
program, and communicate with it.
Moment Tensor
& Source Depth
Inversion Program (
MomTens) retrieves seismic source
parameters
from long
period surface wave spectra and P wave polarity data.
The theoretical basis of the method we use is given in the
Appendix
. The program MomTens uses records of surface wave modes
isolated by FTAN program.
