Influence of Pumice Texture on Magma Decompression Rate Estimates Using Bubble Number Density: Application to the Largest Known Plinian Eruption of Cerro Machin Volcano, Colombia
THE STORAGE, TRANSPORT, AND ERUPTION OF MAGMA USING FIELD OBSERVATIONS, LABORATORY APPROACHES, AND MODELING IV POSTER
volcanology, geochemistry and petrology | 14 december 2022
MaKayla Etheredge, Silvia Castilla , Philip M. Pi...
Bubble size and number in pumice is related to the decompression rate of magma during syneruptive ascent. Rapid magma decompression leads to a high de...
