Yun et al, 2006 Dzurisin, Rev. Geophy., 2003 • Elongate chambers produce strong radial displacements relative to vertical • Sills and flat-topped chambers produce strong vertical relative to radial
Allows Estimation of: • Source depth • Limited chamber geometry (except dikes) • Orientation • Delta V or Delta p *V • Dikes well resolved Cannot Determine: • Absolute Chamber Volume • Pressure change • No Predictive Capability
