Precursory velocity changes prior to the 2019 paroxysms at Stromboli volcano, Italy, from coda wave interferometry Open
Open-conduit basaltic volcanoes are susceptible to sudden transitions from mild activity to violent explosive eruptions with little to no warning. Such was the case at Stromboli in the summer of 2019, when two paroxysmal explosions occurre…

Weak Crust Owing Past Magmatic Intrusions Beneath Campi Flegrei Identified: The Engine for Bradyseismic Movements? Open
Calderas often experience extended periods of unrest that are challenging to relate to a magmatic or hydrothermal origin, making it crucial to assemble a clear picture of these dynamics. Since 2005, Campi Flegrei caldera (Italy) has experi…

Eruption triggering Open
Volcanic systems behave episodically and require mechanisms for magma segregation, instability and ascent. Here, we discuss the processes that promote the ascent of magma to the Earth's surface and prepare the onset of an eruption, thus ac…

Weak crustal layer beneath Campi Flegrei (Italy) identified: what's its impact on unrest? Open
Calderas often experience prolonged periods of unrest that are challenging to attribute to magmatic or hydrothermal origins, making it critical to develop a clear picture of these dynamics. The Campi Flegrei caldera (CFc), in southern Ital…

MANGO Toolbox: Mitigating Atmospheric Noise with GNSS Observations Open
From repeat-pass interferometry (dInSAR), tropospheric signals often prevent the detection of ground deformation signals on active volcanoes. In past years, different tropospheric corrections have been implemented in InSAR automated proces…

Seasonal Snow Cycles and Their Possible Influence on Seismic Velocity Changes and Eruptive Activity at Ruapehu Volcano, New Zealand Open
Understanding volcanic eruption triggers is critical toward anticipating future activity. While internal magma dynamics typically receive more attention, the influence of external processes remains less understood. In this context, we expl…

Investigating the velocity of magmatic intrusions and its relation with rock fracture toughness: insights from laboratory experiments and numerical models Open
Summary A key question for those who study magmatic and volcanic processes is: ‘How fast can a magmatic intrusion travel?’ Observations and models indicate ranges between 10−2 and 1 m s−1 depending on several parameters, including magma bu…

Insights Into Venus' Crustal Plateaus From Dyke Trajectories Below Craters Open
On Venus, radar observations of the surface have highlighted two categories of craters: bright‐floored, interpreted as pristine, and dark‐floored, interpreted as being partially filled by lava. While volcanic resurfacing occurs within and …

How H2O transport and trapping affect the dynamics of magmatic systems from melt generation to eruption triggering Open
H2O and other volatiles play a major role in the dynamics of magmatic systems from magma source to volcanic eruption. At the source, H2O facilitates melting and within the crust, H2O fluxing of hot rocks favours the formation and stabilisa…

Assimilation of geodetic data for volcanic hazard assessment in near-real time by means of a particle filter Open
In a perspective of volcanic hazard assessment, it is fundamental to be able to determine as early as possible whether, where and when the magma that has started to propagate from the storage zone will reach the surface. The propagation ph…

Interplay between rifting-induced extension and surface loading effects illustrated by lateral magma propagation at Nyiragongo volcano Open
The lateral magma propagation is a common feature of rift zones, with vertical dykes flowing parallel to the rift direction and opening against the minimum compressive stress. Depending on the competition between vertical and lateral magma…

Geodetic observations of simultaneous rift-scale magma inflow in multiple sills in the Central Afar rift Open
During plate spreading, large volumes of magma can be extracted from the upper mantle and intrude the crust. Geophysical and geochemical studies at active magmatic rifts and passive margins show that crustal intrusions mainly occur in the …
