The Magnetization of an Underwater Caldera: A Time‐Lapse Magnetic Anomaly Study of Axial Seamount
Geophysical Research Letters, 2022 Axial Seamount in the northeast Pacific erupted in 2015, 2011, and 1998. Although monitored by the Regional Cabled Array of the Ocean Observatory Initiative, few magnetic surveys have been conducted over the region.

Learning volcanology: Modules to facilitate problem solving by undergraduate volcanology students
Statistics in Volcanology, 2016 Six modules are presented that are designed for use in an undergraduate physical volcanology course. Each module uses a four-step mathematical problem-solving approach following Polya’s How to Solve It, to guide students to: (i) understand the problem, (ii) devise a plan for solving the problem, (iii) implement the plan, and (iv) reflect on their ...

DensityX: A program for calculating the densities of magmatic liquids up to 1,627 °C and 30 kbar
Volcanica, 2019 Here we present a standalone program, DensityX, to calculate the densities of hydrous silicate melts (1,000s of samples in a single model run) given pressures, temperatures, and major oxide compositions in wt% in the 10-component system SiO2-TiO2-Al2O3 ...

Forward scattering effects on muon imaging [PDF]
H. Gomez et al, JINST 12 (2017) P12018, 2017 Muon imaging is one of the most promising non-invasive techniques for density structure scanning, specially for large objects reaching the kilometre scale. It has already interesting applications in different fields like geophysics or nuclear safety and has been proposed for some others like engineering or archaeology.

New magnetotelluric soundings in the Mt. Somma-Vesuvius volcanic complex: preliminary results
Annals of Geophysics, 2000 During 1997 ten magnetotelluric (MT) soundings were recorded in single-site mode above the Mt. Somma-Vesuvius volcanic area. A first campaign of MT measurements was carried out, during spring, by the researchers of the University of Padua with their MSPM

Volcanic Diffuse Volatile Emissions Tracked by Plant Responses Detectable From Space
Geochemistry, Geophysics, Geosystems, 2023 Volcanic volatile emissions provide information about volcanic unrest but are difficult to detect with satellites. Volcanic degassing affects plants by elevating local CO2 and H2O concentrations, which may increase photosynthesis.

Volcanologic investigations at Kilauea [PDF]
American Journal of Science, 1917 The lava column at Halemaumau consists of a main semisolid incandescent body (bench magma), perforated by small shafts leading to a saucer on its summit, which contains a shallow lake of liquid lava. The bench magma grades by decreasing viscosity upward into the lava lake and downward into a more fluid part of the magma column.

Fundamentals of Physical Volcanology [PDF]
Eos, Transactions American Geophysical Union, 2010 Fundamentals haunt me. Certain words ignite unavoidable trains of thought, trains that begin in a cascade, unexpectedly leaping chasm after chasm, rushing from single words to whole paragraphs to full books to men's lives. So it is with me with seeing the word “fundamental” in print.

On the volcanological evolution of Campi Flegrei
Eos, Transactions American Geophysical Union, 1987 Campi Flegrei (Phlegrean Fields) is a Holocene caldera located west of the city of Naples in an area of regional extension [Finetti and Morelli, 1974; Scandone, 1979]. The erupted products range in composition from K basalts to alkali trachyte and phonolite. The complex has been active since at least 47,000 yr B.P.
