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,

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

, 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.

, 1994 The paroxysmal 1883 eruption of Krakatau volcano in Indonesia discharged at least 6.5 km3 (dense rock equivalent) of pyroclastic material into the shallow waters of the Sunda Straits within a 15 km radius of the volcano.

Earth, Planets and Space, 2019 Three lava flows (Buenavista, Xalitzintla and Nealtican) and pyroclastic density currents (Lorenzo and Pink Pumice) from two Popocatepetl Plinian eruptions were sampled for paleomagnetic dating.

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Nishinoshima is a volcanic island in the Ogasawara Arc that has exhibited intermittent activity since 2013, including four major eruptive episodes: 2013–2015 (Episode 1), 2017 (Episode 2), 2018 (Episode 3), and 2019–2020 (Episode 4). Previous studies reported a change in eruption style—from a Strombolian eruption with lava flows (Episode 1 to the early

Experiments on gas-fluidised granular flows and implications for pyroclastic flow mobility
, 2002 International audienceGranular flows were generated by the release of beds of particles in various fluidized states, which then deaerated in a horizontal channel. We describe characteristics of the flows and their deposits.

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 6, June 2026.Abstract We present the results of the first geological mapping of the western half of the Eminescu Quadrangle (H09) on Mercury. Multiple data sets from the NASA MESSENGER Mercury Dual Imaging System instrument were used to produce a geological map covering the area between 72°E and 108°E longitude and 22.5°N and 22.5°S latitude.

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.
