Simply pyroclastic currents

, 2017
Gravity-driven, ground-hugging gas-pyroclast mixtures produced during explosive volcanic eruptions define a full spectrum of particle concentration, flow regime and particle support mechanisms.

PDCD-DAT – a global database of pyroclastic density current deposit field data

Journal of Applied Volcanology
Pyroclastic density currents represent one of the deadliest hazards posed by active volcanoes. Analysis of their deposits provides valuable insights into their internal dynamics and informs numerical simulations of pyroclastic density currents which ...

Evidence for Recent Large Magnitude Explosive Eruptions at Damavand Volcano, Iran with Implications for Volcanic Hazards [PDF]

Journal of Sciences, Islamic Republic of Iran, 2009
Damavand is a large dormant stratovolcano in the Alborz Mountains of northern Iran located in one of the most populous provinces, which could be adversely affected by tephra fall from Damavand.

INVASION OF Acacia decurrens WILLD. AFTER ERUPTION OF MOUNT MERAPI, INDONESIA

Biotropia: The Southeast Asian Journal of Tropical Biology, 2017
Eruption of Mount Merapi in 2010 caused a dense cover of Acacia decurrens Willd., which is an Invasive Alien Plant Species (IAPS). The dense cover happened in all areas of Mount Merapi National Park (MMNP) in Java, Indonesia.

A Geophysical Crustal Model of Central Italy for Geoneutrino Predictions in Borexino

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Predicting the geoneutrino signal at underground detectors requires a local crustal reference whose precision matches the experimental uncertainty. The current Borexino reference is 15 years old and deterministic. We replace it with GUESS, a probabilistic 3‐D model of the Gran Sasso region, built by Bayesian inversion of multi‐source ...

An Experimental Study of Particle‐Laden Jet Noise as an Analogue to Tephra‐Laden Volcanic Eruptions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Explosive volcanic eruptions produce vast amounts of acoustic energy, generally in the infrasound range. For sustained eruptions, infrasound is often dominated by jet noise, a form of noise similar to the sound from human‐made jet engines. Jet noise largely results from the combination of two sound‐producing components: fine‐scale turbulence ...

Observations and modelling of soil slip-debris flow initiation processes in pyroclastic deposits: the Sarno 1998 event [PDF]

Natural Hazards and Earth System Sciences, 2003
Pyroclastic soils mantling a wide area of the Campanian Apennines are subjected to recurrent instability phenomena. This study analyses the 5 and 6 May 1998 event which affected the Pizzo d’Alvano (Campania, southern Italy).

Sedimentation and mobility of PDCs: a reappraisal of ignimbrites’ aspect ratio

Scientific Reports, 2017
The aspect ratio of ignimbrites is a commonly used parameter that has been related to the energy of the parent pyroclastic density currents (PDCs). However this parameter, calculated as the ratio between the average thickness and the average lateral ...

Counterfactual Analysis of Runaway Volcanic Explosions

Frontiers in Earth Science, 2019
“Few, beside the student of such phenomena, will be able to realize what would have resulted from a more concentrated liberation of the accumulating energy if, for instance, instead of being separated into moderate earth movements and gas emissions ...

Photometric Characterization of the Moon's Silicic Sites: Insights Into the Origin of Silica‐Rich Magmas

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Lunar “red spots” have been inferred to be regions of extrusive silicic volcanism based on the analysis of remote sensing observations that suggest SiO2 ${\mathrm{S}\mathrm{i}\mathrm{O}}_{2}$‐rich, FeO‐poor composition and morphologies similar to terrestrial silicic domes.
