Drum Snider Peak
Start: 250000 yBP [1]
Event Type: Explosive
Max VEI: 4 [2]
Description: From Richter and others (1994): "The final stages of cycle 2 constructional volcanic activity probably occurred in the vicinity of Snider Peak on the south flank of Mount Drum (Fig. 3 [in original text]). Extensive dacite lava flows were erupted here at about 300 ka (samples G, E, Fig. 4 [in original text]) followed by the emplacement of the Snider Peak dacite dome at about 250 ka (sample A, Fig. 4 [in original text])."
From Westgate and others (2007): "Large volumes of mostly andesitic lava were erupted, building a large volcanic pile. Several dacite domes formed towards the end of this cycle, including Snider Peak, which is 240 ka and probably represents the last products of constructional volcanic activity on Mount Drum (Richter and others, 1994)."
The Global database on large magnitude explosive volcanic eruptions (LaMEVE; 2017) reports a magnitude of 4.000 , bulk eruptive volume of 0.100 cubic km and a dense rock equivalent eruptive volume of 0.040 cubic km for the eruption.
