El Arrayan Fault

El Arrayan Fault ( Spanish : Falla El Arrayan ) is a geological fault , located inmediataly north of the city of Santiago in Chile. The fault runs in northwest-southeast direction. Likely, the fault was last active sometime in the Quaternary period (last 2.5 million years). ^[1] It is chiefly a strike-slip fault . Fault scarps , sag ponds , mountain saddles and stream deflection are some of the surface features of El Arrayan Fault. ^[1] The fault is estimated to be able to produce 6.4 Mw-strong earthquakes which make it a significant risk factor for the northernmost neighbourhoods of Santiago. ^[1]
