Volcano flank instability imaged by historical air photos correlation during the 1975 M.7.7 Kalapana earthquake (Kīlauea, Hawaii) Open
The Kīlauea volcano is affected by flank instability related to recurrent volcano-tectonic events and large earthquakes. Yet, the connection between fracture zones and large recurrent earthquakes still remains poorly constrained, mainly be…

Tracking magma pathways and surface faulting in the Southwest Rift Zone and the Koaʻe fault system (Kīlauea volcano, Hawai ‘i) using photogrammetry and structural observations Open
Volcanic islands are often subject to flank instability, resulting from a combination of magmatic intrusions along rift zones and gravitational spreading causing extensional faulting at the surface. Here, we study the Koaʻe fault system (K…

Faulting activity during the 2021 oblique rifting event in the Reykjanes Peninsula (SW Iceland) Open
The Reykjanes Peninsula is located at the boundary between the North American and the Eurasian plates. The Peninsula is experiencing an oblique rifting episode that started with a strong earthquake swarm the 24 February 2021, preceded by s…

Tracking magma pathways and surface faulting in the Southwest Rift Zone and the Koaʻe fault system (Kīlauea volcano) using photogrammetry and structural observations Open
Volcanic islands are often subject to flank instability, resulting from a combination of magma intrusions along rift zones, gravitational spreading and extensional faulting observed at the surface. Here we study the Kīlauea volcano in Hawa…

Surface fractures generated during the 2021 Reykjanes oblique rifting event (SW Iceland) Open
We use a comprehensive dataset of field observations, high spatial resolution drone orthomosaics and digital terrain models (DTMs) to map, quantify and characterize the extensive ground fracturing related to the 2021 seismo-tectonic and vo…

Structured elicitation of expert judgement in real-time eruption scenarios Open
Formalised elicitation of expert judgements has been used to help tackle several problematic societal issues, including volcanic crises and pandemic threats. We present an expert elicitation exercise for Piton de la Fournaise volcano, La R…

Sub-surface fault slip dynamics during the 2021 Reykjanes unrest (Iceland) Open
<p>The dynamics of fault slip in the upper hundreds of meters of Earth&#8217;s crust has long been an open question, as their behavior differs from classical elastic dislocation models and their observation still raises challenge…

Widespread ground cracks generated during the 2021 Reykjanes oblique rifting event (SW Iceland) Open
<p>The Reykjanes Peninsula has recently been subject to a seismo-tectonic unrest triggering widespread ground cracks. This started with a strong seismic swarm from 24 February to 17 March 2021 and culminated in a volcanic eruption on…

Gravitational volcano flank motion imaged by historical air photo correlation during the M7.7 Kalapana earthquake (1975), Big Island, Hawaii Open
<p>Volcanic islands are often subject to flank instability, being a combination of magma intrusions along rift zones, gravitational spreading and extensional faulting observable at the surface. The Kilauea is one of the most active v…

How shear helps lava to flow Open
Understanding the thermo-rheological regime and physical character of lava while it is flowing is crucial if we are to adequately model lava flow emplacement dynamics. We present measurements from simultaneous sampling and thermal imaging …

Combining Ground‐ and ASTER‐Based Thermal Measurements to Constrain Fumarole Field Heat Budgets: The Case of Vulcano Fossa 2000–2019 Open
Vulcano Fossa's fumarole field (Italy) has been active for more than a century and has become a well‐studied benchmark for fumarolic degassing, often being considered the “model” hydrothermal system. Satellite thermal monitoring is increas…
