Identification pyroclastic flow of magnetic minerals (Holocene volcano): A case study of paleo-volcano Lawu on the south side, Central Java, Indonesia

Kuwait Journal of Science, 2023
Indonesia is surrounded by three tectonic plates: the Eurasian, Indo−Australian, and Pacific plates. The plates have caused Indonesia to have many volcanoes, both active and inactive, resting, or no longer active.

Legacy of pre‐eruption vegetation affects ground‐dwelling arthropod communities after different types of volcanic disturbance

Ecology and Evolution, 2021
Volcanic eruptions are one of the largest natural disturbances and are followed by the establishment of novel plant and animal communities in terrestrial ecosystems.

Tracking Pyroclastic Flows at Soufrière Hills Volcano [PDF]

Eos, Transactions American Geophysical Union, 2009
Explosive volcanic eruptions typically show a huge column of ash and debris ejected into the stratosphere, crackling with lightning. Yet equally hazardous are the fast moving avalanches of hot gas and rock that can rush down the volcano's flanks at speeds approaching 280 kilometers per hour. Called pyroclastic flows, these surges can reach temperatures

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.

Numerical Simulation of Pyroclastic Flow of Karangetang Volcano Based on 2015 Eruption Activity

JGEET: Journal of Geoscience, Engineering, Environment and Technology
On 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

New developments in the analysis of column-collapse pyroclastic density currents through numerical simulations of multiphase flows [PDF]

Solid Earth, 2012
A granular multiphase model has been used to evaluate the action of differently sized particles on the dynamics of fountains and associated pyroclastic density currents.

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 ...

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...
