Combining experimental volcanology, petrology and geophysical monitoring techniques [PDF]
, 2012 In general, an understanding of the complex processes acting before and during volcanic eruptions is approached from various different sides, e.g. laboratory experiments on fragmentation and/or bubble burst eruption mechanisms, petrological analysis of ...

What causes subsidence following the 2011 eruption at Nabro (Eritrea)?
Progress in Earth and Planetary Science, 2018 A major goal in volcanology is to be able to constrain the physical properties of a volcanic system using surface observations. The behaviour of a volcanic system following an eruption can provide powerful constraints on these properties and can provide ...

Physical volcanology of the 2,050 bp caldera-forming eruption of Okmok volcano, Alaska [PDF]
Bulletin of Volcanology, 2005 In the Aleutian volcanic chain (USA), the 2050 ± 50 BP collapse of Okmok caldera generated pyroclasts that spread over 1000 km2 on Umnak Island. After expelling up to 0.25 km3 DRE of rhyodacitic Plinian air fall and 0.35 km3 DRE of andesitic phreatomagmatic tephra, the caldera collapsed and produced the 29 km3 DRE Okmok II scoria deposit, which is ...

Physical Volcanology and Facies Analysis of Silicic Lavas: Monte Amiata Volcano (Italy)
, 2023 Monte Amiata (Italy) is a middle Pleistocene silicic volcano characterized by the extrusion of extensive (5–8 km long and 60 m thick on average) sheet-like lava flows (SLLFs). It is one of the prime volcanoes that have been involved in the volcanological debate on the genetic interpretation of large silicic flows. We performed integrated stratigraphic,

Determining physical and mechanical volcanic rock properties via reflectance spectroscopy
, 2021 There are currently no reliable methods to determine rock physical and mechanical properties that are not labor or resource intensive, especially at the scale of volcanoes.

Volcanic geology and physical volcanology of Mount Morning, Antarctica [PDF]
, 2019 Mount Morning is 70 km south of Ross Island and is part of the Cenozoic McMurdo Volcanic Group, which includes the presently active Erebus volcano. Few previous studies have investigated the mountain.

Multifractal structure and Gutenberg–Richter parameter associated with volcanic emissions of high energy in Colima, Mexico (years 2013–2015) [PDF]
Nonlinear Processes in GeophysicsThe evolution of multifractal structures in various physical processes, such as climatology, seismology, or volcanology, serves as a crucial tool for detecting changes in corresponding phenomena.

Journal of Volcanology and Geothermal Research, 2019 Abstract The experimental approach has become a major tool increasingly used by volcanologists in recent decades to investigate the physics of eruptive processes in complement to field and theoretical works. Researchers have developed various methodologies to study volcanic phenomena at reduced length scale.
