Maderas volcano is a basaltic to dacitic stratovolcano on the SE end of Ometepe island in Lake Nicaragua. It has a a 800 m wide summit crater which contains the small lake Laguna de Maderas at the bottom.
Maderas is still active, but the latest activity dates back more than 3000 years ago and there are no confirmed eruptions in historical time.

Beschreibung:

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.

1996 lahar and fatalities
A mud flow in September 1996 killed 6 persons in a village on the east flank, but there was no eruption at the volcano. The lahar was caused by heavy rainfall.
