Ambient Noise Correlations with Seismic Networks in Mexico
Abstract
We present ambient noise correlations among several local and regional networks in Mexico. The results show strong arrivals in the primary and secondary microseism bands and also longer-period arrivals up 85 seconds. The correlations provide a method of joining detailed local studies into a larger regional map. The dense arrays, such as the MASE array in central Mexico often show coherent scattering that is evidence of major lateral variations in the crust. The travel times shows the response of the local fast anomaly associated with the Popocatepetl Volcano, near Mexico City. There is also a significant lateral change associated with the Trans-Mexican Volcanic Belt.
