IMEX_SfloW2D 1.0: a depth-averaged numerical flow model for pyroclastic avalanches [PDF]
Geoscientific Model Development, 2019 Pyroclastic avalanches are a type of granular flow generated at active volcanoes by different mechanisms, including the collapse of steep pyroclastic deposits (e.g., scoria and ash cones), fountaining during moderately explosive eruptions, and crumbling ...

Post-eruptive flooding of Santorini caldera and implications for tsunami generation
Nature Communications, 2016 The Bronze Age eruption of Santorini is known to have generated tsunamis with caldera collapse as the likely mechanism. However, new bathymetric and seismic data presented by Nomikou et al.

Floristic Composition of Groundcover Vegetation after the 2010 Pyroclastic Fire on Mount Merapi
Jurnal Manajemen Hutan Tropika, 2013 Mount Merapi with its Merapi-type pyroclastic flows provides burnt and unburnt areas which are excellent to study establishment events of pioneer plant species. Using site comparison approach, floristic composition was studied, and thus an area that was

High Potash Volcanic Rocks and Pyroclastic Deposits of Damavand Volcano, Iran, an Example of Intraplate Volcanism [PDF]
Journal of Sciences, Islamic Republic of Iran, 2017 Damavand is a fascinating dormant stratovolcano, 60 km to the ENE of Tehran located in the Alborz Mountains. Damavand volcanic products consist of lava flows and pyroclastic fall, flow and surge deposits from different eruption cycles. The volcanic rocks

Topography and Volcanology of the Huangtsuishan Volcano Subgroup, Northern Taiwan
Terrestrial, Atmospheric and Oceanic Sciences, 2010 Combining the shaded relief topography model and the slope map from the Digital Terrain Model (DTM) images, toporaphical map, field occurrences and petrography, the volcanic sequences of the Huangtsuishan Volcano Subgroup (HVS) can be constructed.

Pyroclastic Flow Deposits and InSAR: Analysis of Long-Term Subsidence at Augustine Volcano, Alaska
Remote Sensing, 2016 Deformation of pyroclastic flow deposits begins almost immediately after emplacement, and continues thereafter for months or years. This study analyzes the extent, volume, thickness, and variability in pyroclastic flow deposits (PFDs) on Augustine ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
