Pyroclastic type flow,Phreato-Surtsean type and Phreato-Vulcanian type explosions
There are big confusions about some volcanic explosion types.At this point,I need to clear explanations... Subject storage condition of hydraulic flows and magmatic gases on a 'relatively chamber stru.' for lower zone of crater rim.Finally, phenomena on a explosion range from Phreato Vulcanian to Phreato Surtsean by degree of development as sudden of inner heat!Sudden dev. of inner heat effect for nearzone relatively to crater rim on material content is summarying as "pyroclastic type flow". By the way,I cite to wrong condition of a template information as relationship to important tectonic boundaries of every event based on important volcanism events (Fagradalsfjall,LaPalma) of actual times; You are right!LaPalma event realised at a "hotspot point" Next,For nice informations about intraplate volcanism; https://en.m.wikipedia.org/wiki/Intraplate_volcanism https://www.britannica.com/science/intraplate-volcanism https://www.science.org/doi/10.1126/sciadv.ab...
