Numerical Simulation of Pyroclastic Flow of Karangetang Volcano Based on 2015 Eruption Activity
JGEET: Journal of Geoscience, Engineering, Environment and TechnologyOn May 7-9, 2015 the eruptive activity of Mount Karangetang released pyroclastic flows towards the Batuawang River for 3.6 km and hit Kora kora village which is located south of the Main Crater. This pyroclastic flow originated from lava flows during the

A pyroclastic flow deposit on Venus [PDF]
Geological Society, London, Special Publications, 2013 Abstract Explosive volcanism on Venus is severely inhibited by its high atmospheric pressure and lack of water. This paper shows that a deposit located near 16°S, 145°E, here referred to as Scathach Fluctus, displays a number of morphological characteristics consistent with a pyroclastic flow deposit.

Influences of hydrological and hydrogeological conditions on debris flows in peri-vesuvian hillslopes [PDF]
Natural Hazards and Earth System Sciences, 2002 The paper illustrates some results of research carried out to assess factors triggering debris flows which involve the pyroclastic overburdens covering carbonate mountains around Vesuvius.

Assessment of motion-induced fluidization of dense pyroclastic gravity currents
Annals of Geophysics, 2005 The paper addresses some fundamental aspects of the dynamics of dense granular flows down inclines relevant to pyroclastic density currents. A simple mechanistic framework is presented to analyze the dynamics of the frontal zone, with a focus ...

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Geological Journal, EarlyView.New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Geological Journal, EarlyView.The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

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.
