A review of recent advances in the field of rheology of multicomponent silicate melts an multiphase silicate melt suspensions is presented here. The advances include the development of new experimental devices and field and remote sensing methods for measuring the rheologicalproperties of natural melts and magmas. The data obtained from these new technologies serve now as the basis for combining laboratory experiments, theoretical models, numerical simulations and remote sensing data derived from ground, airborne and satellite-based tools in order to model the physico-chemical evolution of magmas during ascent and eruption. These promising approaches combine laboratory experiments, theoretical models, numerical simulations and remote sensing data derived from ground, airborne and satellite-based tools. Each of these sub-disciplines has evolvedrapidly in recent years and the growing range of complementary data appears now to provide anopportunity for the development of multi-disciplinary research. Ultimately, these multidisciplinary initiatives seek to provide near-real-time forecasting of hazardous volcanic processes such as lavaflow field evolution. The results and approaches described here focus on multiphase (i.e. melts,bubbles, crystals) rheology of natural systems and are pertinent to the effusive emplacement of lavas, dykes and sills, as well as, to the eruption dynamics attendi explosive eruptions.
