Oceans of magma: Large Igneous Provinces (LIPS) and plumes
The Mt St Helens eruption of 1989 created world news and called forth expressions from journalists such as ‘the unbelievable power of Nature’ and ‘incredible powers of destruction’. Yet, this eruption pales into insignificance in the light of earlier volcanic events. Mt St Helens is estimated to hav...
