Abstract

Damavand Mountain is a large volcanic system located in the north of Iran. Damavand has not had any recorded activity for 1000 years, but evidences of fumarolic activity have been observed near the summit. Due to the lack of data, there are no geodetic studies of volcanoes in Iran. Damavand magma source is modelled in this paper using Global Positioning System (GPS) instruments and Bernese software was used to process and support the interpretations. The maximum height variation obtained from GPS data was 4.7 mm. Direct modelling carried out in this paper demonstrated that a sill-like source model is the most suitable model to reproduce Damavand surface deformation.
