Peter Kokelaar is a British volcanologist, known for his field studies of volcanoes and volcanic processes ancient and modern.
He subsequently returned to Aberystwyth University, where he completed a PhD on the Ordovician volcanic rocks of the Harlech dome, Snowdonia.
He has worked extensively on the mechanisms of caldera collapse, both at the ancient volcanoes of Glencoe[2] and in the British Lake District.
[3][4] In the late 1990s, Kokelaar was involved in the formal assessment of the UK government's response to the eruption of the Soufriere Hills volcano, on the eastern Caribbean island of Montserrat.
[9] In 2013, Kokelaar was awarded the Murchison Medal by the Geological Society of London in recognition of his contributions to volcanology.
