During the main phase of the 2021 eruption of the Cumbre Vieja volcano (La Palma, Spain), eruptive activity was characterized by Strombolian eruptions, fire fountaining, white and grey ash and gas-dominated plumes, and lava effusion from multiple events. Over the period November 16 to November 26, we recorded continuous time-lapse IR images and opportunistic visible and IR videos of the vent from multiple ground-based locations. We measure the apparent area of the high-temperature gas-and-ash jet and fire fountaining from time-lapse images recorded between 1 and 60 frames/min to investigate the evolution of the explosive activity and of these plumes on minutes to days time scales. We compare plume size estimates from two different angles and vent-camera distances. We will explore periodicity and relationships between neighboring vents and discuss the implications for processes occurring in the shallow-most plumbing system of the volcano.
