Se propone una metodología para obtener acelerogramas en un sitio afectado por varias fuentes sísmicas. El método consiste en: (1) identificar las principales fuentes sísmicas que afectan al sitio; (2) elaborar un análisis de peligro sísmico probabilista; (3) estimar el espectro de peligro uniforme asociado a un periodo de retorno; (4) aplicar un análisis de desagregación del peligro sísmico probabilista; (5) generar movimientos sísmicos simulados de los escenarios sísmicos; y (6) seleccionar el número de movimientos para abarcar por completo el espectro de peligro uniforme. Se obtiene como ejemplo una familia de movimientos sísmicos en terreno firme de la ciudad de México para que sean usados en la práctica. Se muestra que los registros seleccionados son un conjunto muy útil de todos los movimientos posibles que podrían afectar la ciudad y están disponibles para usarse por ingenieros estructurales y eventualmente poderse incluir en el código.
