The build-up and triggers of volcanic eruptions
More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Caldera resurgence during the 2018 eruption of Sierra Negra volcano, Galápagos Islands
Recent large basaltic eruptions began after only minor surface uplift and seismicity, and
resulted in caldera subsidence. In contrast, some eruptions at Galápagos Island volcanoes …

Imaging sub-caldera structure with local seismicity, Okataina Volcanic Centre, Taupo Volcanic Zone, using double-difference seismic tomography
We examine sub-caldera structure and seismicity in and around the Okataina Volcanic
Centre (OVC), Taupo Volcanic Zone, New Zealand, using seismic data collected over 4+ …

A simple two-state model interprets temporal modulations in eruptive activity and enhances multivolcano hazard quantification
Volcanic activity typically switches between high-activity states with many eruptions and low-
activity states with few or no eruptions. We present a simple two-regime physics-informed …

Progressive underplating of mafic material at mid-crustal depth beneath Ischia volcano, Italy
Abstract The destructive (Mw 3.9) earthquake of 21 August 2017 re-opened the question on
where magma resides at the Ischia island volcano. The peculiar complexity of the seismic …

The attenuation of macroseismic intensity in the volcanic island of Ischia (Gulf of Naples, Italy): comparison between deterministic and probabilistic models and …
In this paper, we tackle the problem of the intensity attenuation at Ischia, a critical parameter
in a high seismic risk area such as this volcanic island. Starting from the new revised …

Surface deformations and gravity changes caused by pressurized finite ellipsoidal cavities
We develop quasi-analytical solutions for the surface deformation field and gravity changes
due to the pressurization of a finite (triaxial) ellipsoidal cavity in a half-space. The solution is …

[HTML][HTML] Magmatic volatile content and the overpressure 'sweet spot': Implications for volcanic eruption triggering and style
Volatile exsolution is widely considered to be capable of generating magmatic overpressure
and triggering volcanic eruptions. Despite its role as an eruption trigger, exsolution-driven …

The 2017, MD= 4.0, Casamicciola earthquake: ESI-07 scale evaluation and implications for the source model
On 21 August 2017 at 20: 57 (local time) a very shallow (H= 1.2 km), moderate (Md= 4.0),
earthquake hit the volcanic island of Ischia (Southern Italy), causing the death of two people …

Trapdoor fault activation: A step toward caldera collapse at Sierra Negra, Galápagos, Ecuador
Abstract The 2018 Sierra Negra eruption resulted in meter‐scale subsidence due to basaltic
magma extraction from a deflating reservoir. The eruption was also characterized by dike …
