Preliminary assessment for the use of VORIS as a tool for rapid lava flow simulation at Goma Volcano Observatory, Democratic Republic of the Congo [PDF]
Natural Hazards and Earth System Sciences, 2015 Assessment and management of volcanic risk are important scientific, economic, and political issues, especially in densely populated areas threatened by volcanoes. The Virunga volcanic province in the Democratic Republic of the Congo, with over 1 million

Identification of structural controls in an active lava dome with high resolution DEMs : Volcán de Colima, Mexico [PDF]
, 2012 Monitoring the topography of active lava domes is critical for detecting changes that may trigger or influence collapse or explosive activity. Internal dome structure and conditions are more difficult to elucidate, but also play vital roles.

The Age and Origin of Block Deposits in the Victorian Alps, Australia
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

The genesis of a lava cave in the Deccan Volcanic Province (Maharashtra, India)
International Journal of Speleology, 2016 Lava tubes and channels forming lava distributaries have been recognized from different parts of western Deccan Volcanic Province (DVP). Openings of smaller dimension have been documented from the pāhoehoe flows around Pune, in the western DVP.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The existence of permafrost was explored at tropical latitude on Nevado Coropuna (southern Peruvian Andes) using a combination of ground‐penetrating radar (GPR) and vertical electrical sounding (VES) in order to strengthen the mutual validation of data processing and interpretation.

The anatomy of a channel-fed `a`ā lava flow system
, 2022 International audienceThe stabilized channel is a crucial element of an `a`ā flow system, delivering lava to forward extending zones of dispersed flow. However, the term stable implies that channel geometries, lava properties, and dynamics are invariable.

VolcanicaLava is the primary volcanic hazard on basaltic volcanoes, such as those of Bioko Island (Equatorial Guinea). The last eruption on Bioko occurred in 1923, and current emissions of CO2 indicate the presence of magma at depth and the potential for future ...

Annual Review of Fluid Mechanics, 2000 Lava flows are gravity currents of partially molten rock that cool as they flow, in some cases melting the surface over which they flow but in all cases gradually solidifying until they come to rest. They present a wide range of flow regimes from turbulent channel flows at moderate Reynolds numbers to extremely viscous or plastic, creeping flows, and ...

Building capacity in vector‐borne plant virus research: The CONNECTED Network
PLANTS, PEOPLE, PLANET, EarlyView.Plant viruses spread by insects decimate crop yields globally, causing food security challenges in vulnerable areas, including regions of Africa. Interdisciplinary research is needed to protect future crop supplies. CONNECTED, the Community Network for African Vector‐Borne Plant Viruses, increased research capacity in Central, East, West and Southern ...
