Summary: The occurrence of mantle-derived peridotite xenoliths in phonolitic melts is a rare phenomenon. A unique tephriphonolite lava from Cumbre Vieja volcano in La Palma provides evidence that xenoliths are transported into evolving phonolite melts by mafic magmas. Petrological investigations show that the tephriphonolite magma was stored in the lower crust at high temperatures and oxidized conditions. The peridotite xenoliths had contact with alkaline melts for several decades to centuries before being entrained in the final ascent of the lava.

Summary: The explosive activity of the 2021 Tajogaite eruption is diverse and complex, with various pyroclast ejection modes occurring simultaneously and alternately at multiple vents. The physical parameters of these activities were captured using a camera array and showed a range of velocities and mass fluxes. Despite the variations, there is a gradual shift from one activity endmember to another without clear boundaries. The explosive activity of the Tajogaite eruption shares similarities with violent Strombolian eruptions but with previously undefined dynamics of pyroclast ejection.

Summary: Before the COVID-19 pandemic, the World Tourism Organization (UNWTO) emphasized the need for innovation, sustainability, and accessibility in sun and beach tourist destinations. This study focuses on the geotourism development in La Palma, an island in the Canary Islands, which has faced a tourism crisis exacerbated by the eruption of Tajogaite, Cumbre Vieja in 2021. The research identifies and characterizes points of interest in the two largest population centers, Santa Cruz de La Palma and Los Llanos de Aridane, showcasing the diverse natural and cultural volcanic and non-volcanic heritage of the regions.

Summary: The viscosity of magma plays a crucial role in its migration and eruption. The 2021 eruption of Cumbre Vieja volcano produced highly fluid lava with low viscosity, resulting in high-Reynolds number turbulent flow and supercritical states. The increase in viscosity due to crystallization-induced melt differentiation was not significant in this eruption.

Summary: This study characterizes the temporal evolution of volatiles during the Tajogaite eruption by analyzing the composition of fluid inclusions in erupted lavas. The results show substantial variations in volatile composition during the eruption, which can be explained by the contribution of more primitive magma from the deeper reservoir. The isotopic signatures of helium suggest a mixing of different magma sources.

Summary: The study successfully detected signs of volcanic unrest on La Palma island through satellite radar observations and advanced interpretation techniques, providing an early warning decades before a potential eruption. The results show the changing nature of activity in space and time, providing new insights into the dynamic nature of associated volcanic hazards.

Summary: The 2021 volcanic eruption at La Palma, Canary Islands, was the largest in the island's history. A study using seismological methods found a long preparatory phase with the destabilization of an intermediate reservoir and a co-eruptive phase with seismic activity controlled by the drainage and interaction of two reservoirs.

Summary: The study aims to characterize the mineral assemblage formed by ephemeral fumarolic fields of the Tajogaite volcano in La Palma Island, Canary Islands, Spain in 2021. A total of 73 samples were obtained from different fumarole sectors in the studied area. The mineralization associated with these fumaroles formed efflorescent patches that varied in color and were located at different distances from the volcanic craters. The mineralogical and textural characterization revealed a complex mineral assemblage comprising cryptocrystalline phases related to low and medium temperature conditions. The classification of three different fumarolic mineralization types was proposed based on their composition and occurrence.

Summary: By using Ambient Noise Tomography (ANT), we have successfully constructed a high-resolution seismic velocity model of the first few kilometers of the crust of La Palma island and merged it with a recent local earthquake tomography model. Our findings reveal high-velocity zones in the northern and southern parts of the island, possibly related to plutonic intrusion and old oceanic crust materials. Four low-velocity zones are imaged in the southern part, two of which may be associated with hydrothermal alteration zones beneath the Cumbre Vieja volcanic complex. The comparison of the S-wave velocity model with seismicity recorded during the pre-eruptive phase of the 2021 Tajogaite eruption supports this hypothesis.

Summary: The 2021 La Palma eruption presented a unique opportunity to study the relationship between earthquake hypocenters and magma reservoirs. Using calibrated Raman spectroscopy, we conducted density measurements on CO2-rich fluid inclusions (FIs) in olivine crystals to gain insight into magma storage and transport during the eruption. Our findings, which revealed depths of 15 to 27 km within the reported deep seismic zone, can greatly enhance our understanding of ongoing volcanic activity.

Summary: In this study, the 3-D crustal structure beneath La Palma island in Spain was investigated using data from local earthquakes. The results revealed a high-Vp anomaly beneath the Taburiente caldera, which corresponds to the oldest basal complex. Additionally, a low-V anomaly in the north-south direction was identified in the shallower layers of the southern part of the island, associated with the N-S rift structure in Cumbre Vieja. The presence of an elongated high Vp/Vs anomaly beneath the northwestern part of Cumbre Vieja suggests the possibility of magma reservoirs with partial melt and/or fluids.

Summary: The 2021 Tajogaite eruption on La Palma involved complex hybrid eruptions with simultaneous lava flows and tephra plumes. The tephra blanket provided important insights into the eruptive dynamics. A multidisciplinary approach, including the characterization of tephra, atmospheric conditions, and lava emission, is necessary to understand hybrid eruptions and forecast ash dispersal.

Summary: The 2021 eruption of La Palma was the first subaerial eruption in the Canary Islands in 50 years. The eruption exhibited temporal changes in mineralogy and bulk rock geochemistry, reflecting the evolution of volcanic activity. The study of lavas also provided insight into precursor seismicity and magma activity.
