The depth of the caldera subsidence is the same as obtained with the BARC GPS station until contact was lost in March, the maximum being 62 m.
The volume of the subsidence bowl is now 1.9 km³. This is an increase of about 0.1 km³ since 3rd February. It is likely that most of this volume increase occurred in Febuary.
