El segundo tipo de sismos se denominan corticales o sismos de corteza, producidos debido al repliegue de la placa Continental y generalmente están asociados a fallas geológicas, actividad volcánica o cambios bruscos de los esfuerzos en la corteza terrestre.

folding
I believe it refers to "folding" here.
Continued displacement on a thrust over a ramp produces a characteristic fold geometry known as a ramp anticline or, more generally, as a fault-bend fold.
...
Thrust faults occur in the foreland basin which occur marginal to orogenic belts. Here, compression does not result in appreciable mountain building, which is mostly accommodated by folding and stacking of thrusts.

minor fold
I think Toni was headed in the right direction. "Minor fold" is perfectly acceptable for use in describing complex, multi-episodic deformation.
There is an example here, where we can see the larger folding, with smaller-scale folding on the limbs of the larger folds:

pliegue. (fold) Geol. Estructura de una roca o conjunto pétreo cuando una superficie de referencia, definida como plana antes de la deformación, se transforma en una superficie curvada o doblada. Salvo casos especiales, implica un acortamiento del espacio ocupado originalmente.
repliegue. (minor fold, parasitic fold) Geol. Término aplicado a pliegues menores, de segundo orden o de escala menor, en la charnela o el flanco de un pliegue mayor.
