Forensic Profiling Analogue Approach for the Investigation of Natural Hazards – A Case Study from Onokoba Elementary School, Unzen Volcano, Japan [PDF]
, 2021 Internal temperature variations of pyroclastic flows and their deposits are arguably the most challenging data to acquire. As a preliminary study of the temperature variation inside pyroclastic flows, the remains of Onokoba Elementary School (Shimabara ...

IOP Conference Series: Earth and Environmental Science, 2008 Compositional zonation in ignimbrites is relatively common, and is often inferred to record gradual withdrawal by an eruption of a density-stratified magma chamber (with silicic magma towards the top and more dense, mafic magma at the bottom). We show that this model does not match observations at the ca.

Fossil vs. active geothermal systems: A field and laboratory method to disclose the relationships between geothermal fluid flow and geological structures at depth [PDF]
, 2021 Comparison between fossil and analogue active geothermal systems permit to obtain key-parameters to define a conceptual model of the area under exploration. The approach is based on structural, kinematic, and fluid inclusions analyses.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract Studying the behavior of dormant volcanoes is a major challenge in volcanology. Here, we conducted a 10‐year survey of hydrothermal mineralization at Campi Flegrei, an active volcano near Naples in Italy, which last erupted in 1538. Our survey revealed a significant output of boric acid at the hydrothermal sulfate discharge area of Pisciarelli,

Geofluids, Volume 2024, Issue 1, 2024.Hydrothermal geochemical signatures in outcropping rock samples of the super‐hot Los Humeros geothermal field were discovered by using an integrated geochemometric study of the mobility of components (major oxides) and trace elements. Chemical component and element mobilities were determined by using the Gresens–Grant equation for mass balances.

Caldera collapse and tectonics along the Main Ethiopian Rift: Reviewing possible relationships [PDF]
, 2021 The Main Ethiopian Rift (MER) represents an area where volcanism and tectonics interact to create closely linked volcano-tectonic features. This linkage is paramount in the axial portion of the rift, where magmatic segments localize several large ...
