Pyroclastic flow dynamics and hazard in a caldera setting: Application to phlegrean Fields (Italy)
, 2006 Numerical simulation of pyroclastic density currents has developed significantly in recent years and is increasingly applied to volcanological research. Results from physical modeling are commonly taken into account in volcanic hazard assessment and in

Synthetic aperture radar (SAR)-based mapping of volcanic flows: Manam Island, Papua New Guinea [PDF]
Natural Hazards and Earth System Sciences, 2004 We present new radar-based techniques for efficient identification of surface changes generated by lava and pyroclastic flows, and apply these to the 1996 eruption of Manam Volcano, Papua New Guinea.

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.Abstract Recent discoveries suggest that intact lava tubes exist in the Moon and Mars, crucial for establishing long‐term habitable areas to protect future lunar and Martian dwellers from surface risks. Considering planetary lava tubes as potential natural shelters requires understanding their internal complexity, which is challenging due to the lack ...

Analysis of slope failure mechanism in unsaturated pyroclastic soils, based on testing site monitoring [PDF]
, 2009 In the Campania region the pyroclastic soils resting on the limestone massif are often affected by mudflows. These landslides involve more superficial deposits, products of the volcanic eruption of the districts: Campi Flegrei and Somma Vesuvius.

Preservation of Isolated Vesicles in Submarine Pumice and Implications for Submarine Slope Stability
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Pumice clasts from submarine eruptions contain abundant isolated vesicles that are completely encased in glass. As erupted clasts cool, gas inside isolated vesicles contracts, leading to low pressures inside those vesicles. Despite low pressures, isolated vesicles can be preserved in submarine pumice deposits to water depths of approximately 1–

Aspects of pyroclastic flow movement and emplacement [PDF]
, 1992 Pyroclastic flows are products of explosive volcanic eruptions. Composed of hot gas and particulates, they move as ground hugging density currents. This study utilized comparisons with similar geologic phenomena (e.g.

Remote Sensing, 2019 On 3 June 2018, a strong eruption of the Fuego volcano in Guatemala produced a dense cloud of 10-km-high volcanic ash and destructive pyroclastic flows that caused nearly 200 deaths and huge economic losses in the region. Subsequently, due to heavy rains,

, 2006 Numerical simulation of pyroclastic density currents has developed significantly in recent years and is increasingly applied to volcanological research. Results from physical modeling are commonly taken into account in volcanic hazard assessment and in the definition of hazard mitigation strategies. In this work, we modeled pyroclastic density currents

Ancient pyroclastic flows: an example in the Permian Viar Basin (SW Spain)
, 2002 An example of study about ancient pyroclastic flows deposits is shown in this paper. Rhyodacitic pyroclastic flow deposits have been analyzed in the Permian Viar Basin, SW of Spain. They are associated with others volcanic and sedimentary rocks.

Deposits of pyroclastic mass flows at Bibby Hill (Pliocene, James Ross Island, Antarctica) [PDF]
, 2014 Sedimentological study of the southern slopes of Bibby Hill (relic of a Pliocene tuff cone) allows recognition of twelve lithofacies and three facies associations.
