Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science

09 Jan 2014 | Contributor(s): Steven Kuehn, Solene Pouget, Marcus I Bursik

Tephra deposits are used by diverse communities: volcanologists, petrologists, tephrochronologists, paleoclimatologists, paleoecologists and archaeologists. To perhaps be too reductionist, volcanologists are generally interested in tephra to understand eruption behavior, frequency, and hazards;...
