“…Growing human settlement and tourism on the fertile flanks of basaltic volcanoes increases associated risks. The issue is exacerbated in regions where destructive eruptions predate human memory and perceived risk is low, as sadly exemplified in recent eruptions at Kilauea’s lower east rift in 2018 ( 1 ) and La Palma’s Cumbre Vieja rift in 2021 ( 2 ). To protect human lives and infrastructure, volcano monitoring efforts have improved markedly in the last decades ( 3 ).…”

Understanding the drivers of the onset, evolution, and end of eruptions and their impact on eruption style is critical in eruption forecasting and emergency management. The composition of erupted liquids is a key piece of the volcano puzzle, but untangling subtle melt variations remains an analytical challenge. Here, we apply rapid, high-resolution matrix geochemical analysis on samples of known eruption date spanning the entire 2021 La Palma eruption. Sr isotope signatures reveal distinct pulses of basanite melt driving the onset, restart, and evolution of the eruption. Elemental variations in matrix and microcrysts track progressive invasion, and draining, of a subcrustal crystal mush. Associated variations in lava flow rate, vent development, seismicity, and SO 2 emission demonstrate that volcanic matrix resolves eruption patterns that could be expected in future basaltic eruptions globally.

The 2018 eruption of Kīlauea Volcano was notable for its variety of large and spatially distinct hazards, simultaneously affecting three geographically disparate, culturally diverse regions in Hawaiʻi. We conducted a pilot study, consisting of 18 semi-structured interviews, two survey responses, and several informal conversations with Hawaiʻi residents to learn which sources/messengers of eruption information were deemed most trusted and credible. Participants' perceptions of the U.S. Geological Survey Hawaiian Volcano Observatory (HVO), community-based messengers, and traditional news media can be examined across four themes: relevance, expertise, sincerity, and pace. Among our interview participants, Lower East Rift Zone (LERZ) residents placed the highest trust in their community messengers, summit residents deemed HVO most trustworthy, and Kaʻū residents trusted information from both HVO and local news media. Our findings suggest that future official eruption communications would benefit from 1) designating communications personnel to act as community liaisons and 2) increasing pace and relevance of information delivery.

“…The explosive Hunga Tonga-Hunga Ha'apai eruption that occurred on January 15, 2022, in the Kingdom of Tonga, southern Pacific, evidenced how oceanic and atmospheric perturbations triggered by largemagnitude volcanic eruptions can have impacts on a trans-oceanic or even global scale (Amores et al, 2022;Yuen et al, 2022;Le Mével et al, 2023;Purkis et al, 2023). Moreover, the September-December 2021 eruption of the Cumbre Vieja volcano (Canary Islands, Spain) highlights the devastating character that even smaller-scale eruptions may have in highly populated and exposed areas nearby the volcano (e.g., Houghton et al, 2021;Carracedo et al, 2022;Romero et al, 2022). In this way, the geological study of volcanic deposits, landforms, and structures is fundamental to the understanding of the formation and evolution of volcanoes, including the magnitude and recurrence of their eruptions, and therefore of the associated potential hazards.…”

Geological heritage sites assessment in the northern flank of the Calbuco volcano (Southern Andes, Chile)

Calbuco volcano (41.3° S, Southern Andes) ranks second in the Chilean volcanic risk ranking. The products of Calbuco’s last eruption (April 22-23, 2015) severely affected the surroundings of the volcano, particularly the Ensenada village (~1,500 inhab.), evidencing a growing need for effective volcanic risk management and mitigation. The geological study of volcanic deposits and landforms is a key step in reconstructing past volcanic eruptions and for the evaluation of volcanic hazards and associated risks. Additionally, well-preserved and easily accessible volcanic deposits can be considered as geological heritage sites (geosites) that could be used to educate communities and visitors about geological hazards and volcanic risk through different outreach, educational, and touristic activities. In the northern flank of Calbuco, a series of protected public and private areas (Llanquihue National Reserve, Valle Los Ulmos Park, and Volcanes Park) foster the conservation of natural heritage and facilitate the accessibility to volcanic deposits. Our contribution therefore assesses the geological heritage potential of the northern flank of the Calbuco volcano through literature review, geological mapping, and stratigraphic and petrographic studies of recent eruptive deposits. The identified geosites were scored and ranked through a quantitative procedure. The top three-ranked geosites hold high scientific value and good accessibility conditions. These sites may sustain a geoconservation strategy based on scientific, educational, and touristic activities, contributing thus to volcanic risk reduction in the area.
