Mukus Waterfall

Mukus Waterfall

The morphology of this geosite is in the form of structural hills. The walls of the waterfall which are composed of Andesite-Basalt are the result of the pre-caldera eruption of Mount Masurai and volcanic breccia with andesite and basalt fragments. The normal fault that works is northwest-southeast in this area which cross the Siau River, so that due to the pull of the fault, it forms a waterfall in the middle.
