This project received funding from CONACYT during the period April 2003 to March 2006 (Fondo de Ciencias Básicas CONACYT/SEP 41199). The project has been based at two volcanoes: Volcán de Colima and Isla Socorro. Many studies have been carried out at active volcanoes using the techniques of geophysics, whilst others utilize different tools of geochemistry to model the systems. There are not many studies that link the two fields together. This was the idea behind this project. Several geophysical techniques have been included in the studies: geomagnetics, self-potential, very low frequency method (VLF) and transient electromagnetic method (TEM). Comparisons are being made with the results of measurements of diffuse degassing, thermal emission and the characteristics of gases released from the systems.
The objectives included the following:
Gas and Self Potential measurements over active Fumarole field, Isla Socorro
TEM measurements on the flanks of Volcán de Colima
