Resumen

Resumen: Utilizamos ondas sísmicas para un terremoto de magnitud 6,3 de profundidad intermedia (160 km) en el Nido de Bucaramanga, Colombia, para inferir un complejo proceso de ruptura con dos etapas distintas, caracterizado por diferentes velocidades de ruptura posiblemente controladas por la evolución de la fuerza en la falla. Nuestro procesamiento de datos integrado permitió caracterizar con precisión la ruptura multietapa y la presencia de un fuerte evento de debilitamiento. La radiación sísmica resultante se interpreta como el resultado de un debilitamiento extremo debido a una fuga de cizallamiento térmico en cascada, con un proceso inicial de radiación ineficiente seguido de una ruptura rápida y dinámica eficiente. Nuestros resultados implican una complejidad dinámica de la ruptura sísmica en las profundidades de la Tierra, y pueden ayudar a dar nuevas perspectivas sobre el mecanismo físico de los terremotos de profundidad intermedia.
