To date, there have been reported several quality factors Q(f) = Q₀f^α 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.

迄今为止，已经报道了几种品质因数Q（˚F）= Q ₀ ˚F ^α在文献中用于跨墨西哥火山带（TMVB），两者之间有显著变化。这些研究中的大多数都没有完全指定分析中使用的参数，或者它们依赖震中位于研究区域之外的地震的地震图。在本文中，通过尾气分析确定了TMVB的质量因子。为此，使用了与地震有关的本地记录，震中位于TMVB内部。根据地质特征以及与尾气Q（f）值。结果表明，Q（f）与源的特性和位置有着明显的相关性。与使用不同方法和来源特征报告TMVB的Q（f）值的研究相比，发现了重要的变化。
