The settlement is built around the southern side of a little lake ( Lago Laceno ) , originally a swamp and served by the river Tornola , who has reduced its surface after 1980 Irpinia earthquake , due to some holes opened in the crust . Not too far from Laceno there are some caves ( '' Grotte del Caliendo '' ) , discovered in 1992 by Giovanni Rama
