A GPS survey of sites around the volcano was completed today. The sites measured were at Harris, Whites, Long Ground, Windy Hill and Brodericks. These data will be processed later and results will be reported later in the week.

Results from a deposit of survey of the lower part of the White River valley are now available. The volume increase due to the event on December 26 is 30 million cubic metres. The upper part of the valley and the amount of material below sea level are still to be surveyed.
