  abstract = {{W}e conducted geological and petrological analyses of the tephra fallout and pyroclastic density current ({PDC}) products of the 22-23 {A}pril 2015 {C}albuco eruptions. {T}he eruptive cycle consisted of two sub-{P}linian phases that generated > 15 km height columns and {PDC}s that travelled up to 6 km from the vent. {T}he erupted volume is estimated at 0.38 km(3) (non-{DRE}), with approximately 90% corresponding to tephra fall deposits and the other 10% to {PDC} deposits. {T}he erupted products are basaltic-andesite, 54-55 wt.% {S}i{O}2, with minor amounts of andesite (58 wt.% {S}i{O}2). {D}espite the uniform composition of the products, there are at least four types of textures in juvenile clasts, with different degrees of vesicularity and types and content of crystals. {W}e propose that the eruption triggering mechanism was either exsolution of volatiles due to crystallization, or a small intrusion into the base of the magma chamber, without significant magma mixing or with a magma compositionally similar to that of the residing magma. {I}n either case the triggering mechanism generated convection and sufficient overpressure to promote the first eruptive phase. {T}he start of the eruption decompressed the chamber, promoting intense vesiculation of the remaining magma and an increase in eruption rate towards the end of the eruption.},
