Resumen
Estimates of the quality factor Qs of S waves reported for the regions of Oaxaca and Guerrero, México show that the attenuation in Oaxaca is 3.7 to 5.0 times greater than that in Guerrero for the frequency band from 1 to 30 Hz. This important difference in attenuation of these neighboring regions cannot be completely explained by petrological difference. When the observed values of Qs for Oaxaca and Guerrero are compared with the age of the rocks and the heat flow, it turns out that the attenuation in Oaxaca is greater than expected relative to that in Guerrero. This suggest that the most likely mechanism to explain the observed differences in Qs may be related to the state of stress prevailing when Qs was measured. The high values of Qs estimated for Guerrero can be the result of a less fractured crust and tectonic stress accumulated in this region. KEY WORDS: Guerrero, Oaxaca, attenuation, Q.
