Abstract

 Following the Tephra 2014 Workshop where 1) major developments, 2) best practices, and 3) future directions/needs in tephra studies from both volcanological and tephrochronological perspectives were the main thrusts, this workshop aims to focus on the topics considered most pressing in the field by the attendees of the 2014 workshop (70 internationals).  Two major themes will be considered:  Theme 1) standardization of tephra field data collection, geochemical analysis, correlation, and data reporting, and Theme 2) databases to facilitate information access across disciplines.  

 

Theme 1, standardization, will emphasize pushing forward the production of discipline-based best practice checklists that have been in development since the 2014 workshop.  There will be a special focus on developing best practices for collecting tephra fall immediately after an eruption and calculating eruption volume and mass eruption rate, as well as improving datasets for use in tephra dispersion and fallout modelling.   

 

Theme 2, tephra databases, will discuss the various databases and catalogs and the pros and cons of developing a universal tephra database versus regional databases.  There will be discussion on how to link existing databases, on integrating tools and apps with databases, and on steps forward in data sharing.  Since standardization is the first step toward greater use of databases, we hope that extensive discussion, presentations and consensus decisions on Theme 1 will inform the discussion of databases. 

This workshop will include presentations from experts in tephra field studies, laboratory analysis, and databases. It will facilitate open discussion and will include hands-on breakout sessions.  Concrete outcomes expected from this workshop include best practice training materials, content for grant proposals for database development, and increased interdisciplinary collaboration and data sharing.
