Hazel RymerHazel Rymer is presently the Dean and Director of Studies in the Faculty of Science and Profesor of Environmental Volcanology. Hazel has developed and championed the use of microgravity as a tool for monitoring active volcanoes. She has used this metod to identify sub-surface processes at calderas in a state of unrest and at persistently active volcanoes and this has given geoscientists considerable insight into the range of mechanisms responsible for initiating and sustaining volcanic activity. The technique Hazel pioneered is now the standard method for gravity monitoring on volcanoes; it remains the only way to quantify the sub-surface mass changes that occur before, during and after eruptions.
