 In February 2008, scientists announced that drilling had discovered a scoria cone buried within the mud filling the explosion crater.Although newspaper journalists inferred that the discovered scoria cone was a much younger and different volcano from Panmure Basin, geologists consider that the scoria cone was produced as the second phase of the eruption of Panmure Basin explosion crater and tuff ring.The explosive phase was produced by the interaction of the magma with cold groundwater but once the water was used up the eruption switched to a dry phase of fire-fountaining producing the scoria cone from the same vent.
