The differences between the two types of pyroclastic surge deposits at Irazu are not due to an inherent difference in the eruptive mechanisms but can probably be correlated to different water contents in the moving cloud preventing the elutriation of the fine ash in the case of wet surge, thus preserving the clast size distribution during the fragmentation.
