The Tinguiririca Lahar: its significance among chileans Lahars
Download
Abstract
The Tinguiririca lahar is an example of many similar landforms, which cover
large surfaces 60th in andine valleys and the Chilean longitudinal depression.
I t is smaller than other ones in Chile, but - at the same time - better conserved,
offering good conditions for genetic, kinematic and geochronologic studies,
respecting volcanic mudflows.
From the genetic and kinematic point of view, the longitudinal lahar profile may
be in two parts: a) An upper and middle accumulative area, with concave
transverse profile; b) A low accumulative area; whose transverse profile is convexe.
These two profiles could be explained by means of braking process in
lateral parts, related to central parts, as a function of longitudinal distonces
from the origin.
From the geochronologic point of view, the lahar was between the
Last Glaciation and Late Glacial times. Therefore, i t is more recent than other
ones.
