Abstract
We generated a 13-year InSAR time series from 1995–
2008 to investigate the spatiotemporal characteristics of two
neighboring volcano’s deformations for the Lazufre
volcanic area, central Andes. The data reveal two scales
of uplift initiating during the observation time: (1) a largescale
uplift started in 1997 that shows an increase of the
mean uplift rate of up to 3.2 cm/yr, now affecting several
eruptive centers situated in an area larger than 1800 km2 and
(2) a small-scale uplift located at Lastarria volcano, which is
the only volcano to show strong fumarolic activity in
decades, with most of the clear deformation apparently not
observed before 2000. Both the large and small uplift
signals can be explained by magmatic or hydrothermal
sources located at about 13 km and 1 km deep, respectively.
To test a possible relationship, we use numerical modeling
and estimate that the depth inflating source increased the
tensile stress close to the shallow source. We discuss how
the deep inflating source may have disturbed the shallow
one and triggered the observed deformation at Lastarria.
