Séminaire Constanza Bonadonna – Physical Characterization and Tephra Sedimentation of Long-Lasting Hybrid Eruptions: the 2021 Tajogaite Eruption of Cumbre Vieja (La Palma, Canary Islands)
Séminaire Constanza Bonadonna – Physical Characterization and Tephra Sedimentation of Long-Lasting Hybrid Eruptions: the 2021 Tajogaite Eruption of Cumbre Vieja (La Palma, Canary Islands)
The 2021 hybrid Tajogaite eruption of Cumbre Vieja (La Palma, Spain) was mainly effusive, with >70% of volume erupted as lava and simultaneous explosive activity with variable eruptive styles depositing a widespread tephra blanket. Statistical analyses of pulsatory activity indicate short-time fluctuations amongst the observed multiple eruptive styles, suggesting rapid gas segregation and high magma ascent rate modulating…
