Resumen

El análisis de temblores ocurridos en la costa de Chiapas, Mexico, indica que existe una fuerte atenuación de las señales sismicas (ondas P) en un cierto rango de distancias y azimuts, esto se observa especialmente en las estaciones sismológicas localizadas en el este de Norteamérica. En el presente trabajo se discuten tres posibles explicaciones del origen de este fenómeno, basadas en nuestras observaciones y otros estudios.
