Identifying rheological regimes within pyroclastic density currents
Nature CommunicationsAbstractPyroclastic density currents (PDCs) are the most lethal of all volcanic hazards. An ongoing challenge is to accurately forecast their run-out distance such that effective mitigation strategies can be implemented. Central to this goal is an understanding of the flow mobility—a quantitative rheological model detailing how the high temperature gas-

Earth, Planets and Space, 2016 The phreatic eruption at Ontake volcano on 27 September 2014, which caused the worst volcanic disaster in the past half-century in Japan, was reconstructed based on observations of the proximal pyroclastic density current (PDC) and fallout deposits ...

Sedimentology, EarlyView.ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Temperatures of the A.D. 79 pyroclastic density current deposits (Vesuvius, Italy) [PDF]
Journal of Geophysical Research: Solid Earth, 2004 The temperature of the deposits left by different types of pyroclastic density currents (PDCs) of the A.D. 79 “Pompei” eruption of Vesuvius was estimated by measuring the thermal remanent magnetization (TRM) of lithic clasts carried by the currents. More than 200 lava clasts and roof tile fragments were collected at different sites and distances from ...

Overview of Chaitén Volcano, Chile, and its 2008-2009 eruption
Andean Geology, 2013 Chaitén Volcano erupted unexpectedly in May 2008 in one of the largest eruptions globally since the 1990s. It was the largest rhyolite eruption since the great eruption of Katmai Volcano in 1912, and the first rhyolite eruption to have at least some of ...

Sourcing of Miocene accretionary lapilli on ‘Eua, Tonga; atypical dispersal distances and tectonic implications for the central Tonga Ridge [PDF]
, 2016 Volcaniclastics hosting accretionary lapilli on the Tonga Ridge were sourced from the remnant Lau Ridge, prior to Lau back-arc basin opening. For the ‘Eua occurrences, an atypical dispersal distance of not less than 70 km is estimated, partly arising ...
