PYROCLASTIC FLOW MODELING TO RECONSTRUCT A VOLCANIC EDIFICE IN PAIPA (BOYACÁ-COLOMBIA).

Pyroclastic deposits produced by the domes collapse (resurgence of a caldera collapse), at the west of the Honda Grande creek (Paipa, Boyacá-Colombia) were related by INGEOMINAS. These deposits fill the valleys of Olitas, Calderitas and a creek at the south of the Alto de los Volcanes reaching distances near to 3 km from the focus between the Alto de los Volcanes and El Mirador Hill.The flows were modeled using 3D Software (Sheridan and Kover, 1996). A volcanic simulation was done obtaining the height and morphology of the volcanic edifice before the collapse during the last eruptive event.
