About 1 km east of the Munebrega E Fault there is the 4 km long Valgalindo alluvial fan inset into the Calatayud Graben fill, whose apex points to a topographic gap in the horst, suggesting deposition in response to tectonic subsidence (Fig.

Se ha aceptado por la comunidad geocientifica, que la estructura del valle de la ciudad de Guatemala es una depresion de origen tectonico, tipo graben (Fig 1), delimitada por las fallas de Mixco y Pinula (Weyl 1980; Plafker, 1978; Bonis, 1978; Bonis, 1993); de acuerdo al relieve actual, el desnivel entre los bloques levantados y el graben, donde se encuentra el valle es de 500 m.
