Resumen
A ground deformation network, now comprising 10 km of levelling traverse and six dry tilt stations, has been measured four times since it was first set up at Colima Volcano by the author in 1982. The results show continuous subsidence roughly centred around the summit area, together with a progressive tilt towards the south or southwest. The rate of subsidence averages about 0.4 cm per km each year, though higher rates (around 1 cm per km per year) were measured between 1982-86, and again in 1990-91, in the build up to the 1991 increased in activity. Simple elastic models fitted to the levelling data are consistent with the deflation of a buried source at 2 to 4 km depth, perhaps a magma chamber or the top of a magmatic column. The dry tilt results confirm the subsidence and its variable rate, although parallel tilts often occur in the overall downslope direction, suggesting gravitational creep or sliding of the volcano downslope.
