Explosive volcanic eruptions can eject large quantities of tephra into the atmosphere that can be dispersed and deposited over wide areas. Whilst the hazardous consequences of primary tephra fallout are well known, subsequent remobilisation of ash by aeolian processes can continue to present an...

Workshop on the Impacts associated with the primary fallout of volcanic ash and subsequent aeolian remobilisation, Consensual Document
19 May 2020 | Publications | Contributor(s): Lucia Dominguez, Costanza Bonadonna, Donaldo Bran
The inherent complexity associated with volcanic eruptions and their relationship with societies requires innovative strategies about how we assess and manage risk. The 2011 Cordón Caulle eruption (2011-CC) demonstrated the additional complexity associated with secondary hazards and...

TOTGS: Total grainsize distribution of tephra fallout
20 Jan 2014 | Offline Tools | Contributor(s): Seb Biass, Costanza Bonadonna
NOTE The code is now maintained on GitHub: https://github.com/e5k/TOTGS Follow updates on: https://e5k.github.io/ Quantifying the total grainsize distribution (TGSD) is a necessary step to achieve a thorough characterization of a given tephra deposit. Several methods exist to...
