Lithological heterogeneities below the Kīlauea caldera before its 2018 collapse inferred from ground magnetic anomalies - Dataset
Organisation : Observatoire de Physique du Globe de Clermont-Ferrand

The 2018 crisis of Kīlauea volcano stands as a major event in its evolution with a large down-rift effusive eruption that drained a shallow magma reservoir at the summit. The characterization of such active magmatic systems and associated hazardous events remains a necessity and a challenge. The summit area is hydrothermally active and strongly altered as indicated by geological mapping. A unique dataset of geophysical measurements was collected around Halemaʻumaʻu crater before its collapse. Magnetic data are interpreted here in combination with geological information, temperature anomalies at the surface, self-potential measurements, and a model of electrical conductivity. 3D forward models show that the main magnetic dipole-like anomaly observed around the crater is not only caused by the crater topography but suggest the presence of an important volume of weakly magnetic material beneath the crater, and which may be caused by higher temperature and/or hydrothermal alteration. 3D inversion of the data allows us to explore the first order geometry of the magnetic structures. We complemented it with 2D forward modeling in order to refine the geometry of major structures. The 2018 collapsed area was thus lithologically heterogeneous with several major mechanical contrasts that likely played a role in the geometry of the collapse. Therefore, mapping magnetic anomalies and monitoring their temporal evolution are of great interest for constraining the nature and mechanical properties of the underlying formations and their evolution in order to help predict future behavior.

Characterization and Parameterization of INP Concentration Variability Regarding the Source Emissions Origin
Organisation : Observatoire de Physique du Globe de Clermont-Ferrand

In this work, a three-month INP measurement campaign was conducted at the PUY station (France, 1465m a.s.l) during winter of 2023. The origin of sampled air masses was determined through 72-hour back-trajectory analysis, allowing for the identification of the contribution of specific environments (oceanic, continental clean and polluted, Saharan dust) to the measured IN activity. We then generated a set of parameterizations that are capable to reproduce the variability observed during this campaign. 

This Dataset contains the data measured during this campaign including INP concentration, measurement temperature, black carbon content, total particle concentration, dust concentration and all variables resulting from air mass classification.

A unique electrical resistivity experiment reveals the 3D interior of Piton de la Fournaise - Dataset
Organisation : Observatoire de Physique du Globe de Clermont-Ferrand

Understanding the internal structure of volcanoes is essential for improving eruption predictions and assessing hazards. Achieving high-resolution 3D models of their interiors remains challenging. At Piton de la Fournaise, we used 3D electrical resistivity tomography to generate the first high-resolution image beneath the Terminal Cone, extending to one kilometer deep. Our model reveals a large hydrothermal zone beneath layered lava flows, with conductive offshoots extending toward the surface beneath the Bory crater and along faults linked to the Dolomieu crater. These results indicate that hydrothermal activity is strongly influenced by volcano-tectonic features at the summit. This study provides valuable insights into fluid circulation, magma transfer, and instability, offering a new framework for understanding the spatio-temporal evolution of Piton de la Fournaise and other volcanoes worldwide.
