Melnick explained to the media that the fault, discovered in the town of El Yolki, shows a deformation in the last 4,000 years, but does not have a clear surface rupture, so it is 'hidden,' which does not mean it cannot cause an earthquake.
The research highlights the millennial variations in faults and the seismic cycle of major earthquakes in Chile, with global implications for assessing the dangers posed by hidden, but potentially seismogenic coastal faults along subduction zones. ■
