Ground deformation patterns at White Island volcano (New Zealand) between 1967 and 2008 deduced from levelling data
a b s t r a c t a r t i c l e i n f o Since 1967, levelling measurements have been conducted in the main crater of White Island volcano. Interpretation of these data using numerical modelling reveals that shallow pressure sources (200-600 m deep) extending up to the subsurface dominated the long-ter...
