It has a a 800 m wide summit crater which contains the small lake Laguna de Maderas at the bottom.

Volcán Maderas is cut by numerous faults and grabens, the largest of which is a NW-SE-oriented graben that cuts the summit and has at least 140 m of vertical displacement. The summit crater is located at the western side of the central graben.

The SW side of the volcano has been affected by large-scale slumping. There are many flank cones on the lower NE flank down to Lake Nicaragua.
