Quaternary sediments in the vicinity of Somoto town (Nicaragua)
Abstract
A mountainous denudation relief is typical of the environs of Somoto town in NW Nicaragua, nevertheless some patchily developed Quaternary sediments were identified there. Several meters thick accumulations of sandy gravel with surfaces at the elevation of 10-20 m and 30-90 m above the valley floors are the most conspicious. The gravels are usually poorly sorted and rather coarse grained and represent probably relics of alluvial fans. The slope sediments and mixed deluviofluvial deposits of periodical mountain streams were identified in places. The most dangerous natural hazards are land-slides and flush floods in can-yon-like deep incised valleys.
