Geophysical evidence of first stages of inflation in Domuyo volcanic center in northwestern Neuquén province, Argentina

Cerro Domuyo, in northwestern Neuquén province of Argentina, shows notable geothermal activity, although it is located at a considerable distance from the actual volcanic arc. Many studies have been developed this area with aim investigating its field. Despite these efforts, characterization dynamic activity still poorly known. This work results network seismological stations, which registered volcano-tectonic, long-period and hybrid events. A large number volcano-tectonic events concentrated mostly Domuyo were detected. These can be divided into two groups, those that occurred shallow depths below greater high region Domuyo. Shallow around Manchana Covunco fault many them particularly clustered intersection Humazo fault. Seismicity faults are continually active due to fluid movement, as was evidenced by hydrothermal manifestation 2003. Moreover, new provide evidence experiencing an important inflation caused magmatic body. Deep evidencing activity. Considering between arc study region, density events, highly likely body increasing Additionally, aeromagnetic anomaly over showing thin magnetic crust less than 6 km, suggesting clear link geophysical
