MVO Geologist Mick Strutt alongside AVTIS at Perches

Although AVTIS can see through cloud, the only direct line of sight to the dome available was from Perches at the east end of the southern crater rim. Perches requires clear weather to allow safe helicopter access. Despite being lucky enough to have some exceptionally clear views when we did get to Perches, low cloud levels restricted AVTIS to only  three deployments at Perches over the course of the field trip. On days when access was limited AVTIS was deployed at alternative sites around the volcano to build up as complete a reconstruction of the flank topography as possible.
