PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data

PYFLOW_2.0 is a hazard tool for the calculation of the impact parameters of dilute pyroclastic density currents (DPDCs). DPDCs represent the dilute turbulent type of gravity flows that occur during explosive volcanic eruptions; their hazard is the result of their mobility and the capability to later…

Geoheritage of Volcanic Harrats in Saudi Arabia [Authors: Moufti, Mohammed Rashad, Németh, Károly]

This book records the geoheritage values of globally significant, yet little-known, volcanic geosites in Saudi Arabia. It is the first of its kind to focus on the Middle East, clearly showing the hidden geoheritage value of the volcanic Arabian Peninsula’s harrats and demonstrating why the Saudi Ara…
