These problems are related to lithology, landform and human activity. Deposits from the San Miguel volcano consist of ash, pumice, pyroclastic flows and lahars, as well as conglomerate and fanglomerate. The predominant landform is a sloping surface dissected by deep parallel ravines and their tributaries… in order to continue, download the full paper in PDF.
