Resumen:
To date, there have been reported several quality factors Q(f) =
Q(0)f(alpha) in the literature for the Trans-Mexican Volcanic Belt
(TMVB), with significant variations between them. Most of these studies
do not fully specify the parameters used in their analyses or they rely
on seismograms of earthquakes whose epicenter lies outside the study
zone. In this paper, quality factors were determined for the TMVB from
the analysis of coda waves. For this purpose, there were used local
records related to earthquakes with the epicenter lying inside the TMVB.
A division of the study area is considered according to the geological
characteristics, and a correlation with the coda Q(f) values was
obtained. Results show a clear dependenceof Q(f) on the characteristics
and location of the source. Important variations were identified in
comparison with studies that report Q(f) values for the TMVB using
different methodologies and source characteristics.
