The Vanishing Volcanic Geoheritage of a Key Scoria Cone and its Significance in Volcanic Hazard Resilience of the Active Monogenetic Volcanic Field near Al Madinah, Kingdom of Saudi Arabia [PDF]
Geoconservation Research, 2023 Four small scoria cones in the western outskirts of Al Madinah City, the Kingdom of Saudi Arabia, form a distinct young volcanic landmark. These volcanoes, despite their very small size, provide one of the most fundamental sources of information about ...

Open-vent volcanoes fuelled by depth-integrated magma degassing
Bulletin of Volcanology, 2022 Open-vent, persistently degassing volcanoes—such as Stromboli and Etna (Italy), Villarrica (Chile), Bagana and Manam (Papua New Guinea), Fuego and Pacaya (Guatemala) volcanoes—produce high gas fluxes and infrequent violent strombolian or ‘paroxysmal ...

Lithospheric Sill Intrusions and Present‐Day Ground Deformation at Rhenish Massif, Central Europe
Geophysical Research Letters, 2023 The Rhenish Massif in Central Europe, which includes the Eifel Volcanic Fields, has shown ongoing ground deformation and signs of possible unrest. A buoyant plume exerting uplift forces at the bottom of the lithosphere was proposed to explain such ...

Critical Fluid Injection Volumes for Uncontrolled Fracture Ascent
Geophysical Research Letters, 2020 Hydrofracturing is a routine industrial technique whose safety depends on fractures remaining confined within the target rock volume. Both observations and theoretical models show that, if the fluid volume is larger than a critical value, pockets of ...

The activity of the Kurile Volcanoes in 2018 [PDF]
Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019 Based on visual and satellite data, the authors provide information that characterizes the volcanic activity in the Kuril Islands in 2018.

CO2 flux emissions from the Earth’s most actively degassing volcanoes, 2005–2015
Scientific Reports, 2019 The global carbon dioxide (CO2) flux from subaerial volcanoes remains poorly quantified, limiting our understanding of the deep carbon cycle during geologic time and in modern Earth.

Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]
, 2003 It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...

An Improved Global Analysis of Population Distribution in Proximity to Active Volcanoes, 1975-2015
ISPRS Int. J. Geo Inf., 2019 Better and more detailed analyses of global human exposure to hazards and associated disaster risk require improved geoinformation on population distribution and densities.

Journal of Geophysical Research: Solid Earth, 2019 Volcanoes are hazardous to local and global populations, but only a fraction are continuously monitored by ground‐based sensors. For example, in Latin America, more than 60% of Holocene volcanoes are unmonitored, meaning long‐term multiparameter data ...
