It has well developed levees.ActivityThe noticeable lava flow is of Holocene age.Ground deformation has been observed by InSAR observation, centered southeast of Auquihuato and with a circular shape. The ground deformation may be caused by changes in the pressure within the volcano's magma system, at depths probably exceeding.
