Lava flow impacts on the built environment: insights from a new global dataset

Journal of Applied Volcanology
The recent destruction of thousands of homes by lava flows from La Palma volcano, Canary Islands, and Nyiragongo volcano, Democratic Republic of Congo, serves as a reminder of the devastating impact that lava flows can have on communities living in ...

Pulsatory andesite lava flow at Bagana Volcano [PDF]

, 2012
Using a time series of TerraSAR-X spaceborne radar images we have measured the pulsatory motion of an andesite lava flow over a 14-month period at Bagana volcano, Papua New Guinea. Between October 2010 and December 2011, lava flowed continuously down the

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland

Boreas, EarlyView.
Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

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

Lava flows are fractals

Geophysical Research Letters, 1992
We have conducted a preliminary investigation of the fractal nature of the plan‐view shapes of lava flows in Hawaii (based on field measurements and aerial photographs) as well as in Idaho and the Galapagos Islands (using aerial photographs only). Our results indicate that the shapes of lava flow margins are fractals. In other words, lava flow shape is

Impact vesiculation – a new trigger for volcanic bubble growth and degassing [PDF]

, 2007
We highlight a potentially important trigger for bubble growth and degassing in volcanic bombs. We have successfully triggered bubble growth in previously unvesiculated samples of silicate melt during experiments to simulate volcanic bomb impact, by ...

Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows [PDF]

, 2011
Simple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite.

Unravelling textural heterogeneity in obsidian:shear-induced outgassing in the Rocche Rosse flow [PDF]

, 2015
Obsidian flow emplacement is a complex and understudied aspect of silicic volcanism. Of particular importance is the question of how highly viscous magma can lose sufficient gas in order to erupt effusively as a lava flow.

A Systematic Review Evaluating Methods for Diagnosis, Treatment and Prevention of Dental Erosions

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Aim The aim of this systematic review was to investigate the quality of evidence for methods used to diagnose, restore and prevent dental erosions, by evaluating and summarising clinical controlled studies and in situ studies covering this field.

Lava flow hazard assessment on Bioko Island (Equatorial Guinea) - A probabilistic approach using Q-LavHA

Volcanica
Lava 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 ...
