  1. Workshop on Wind-remobilisation processes of volcanic ash, Consensual Document

    24 Feb 2020

    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...
