*	Tephrochronological frameworks and paleoenvironmental reconstructions  (marine, ice-cores, and terrestrial records), such as INTREPID, INTIMATE and PAGES projects
*	Tephra studies and archaeology
*	Regional studies
*	Geochemical protocols and methods and their development
*	Chronological development and databases
*	Objective correlation and quantification of uncertainty
*	Explosive volcanism
*	Magma genesis
*	Hazards in volcanic regions

Kyushu area (especially Kagoshima) is the best place to discuss about tephra related subjects as explained previously, in this circular. This scientific program is tightly related to the new project of INTREPID (Enhancing tephrochronology as a global research tool) (see INTAV website http://www.env.auckland.ac.nz/about_us/intav.shtml) and an interlaboratory comparison exercise (see http://www.env.auckland.ac.nz/about_us/intav_lab.shtml).　Participants are encouraged to submit papers on any topic involving tephra studies (such as characterization, correlation, methodology) and their application in palaeoenvironmental, archaeological, and volcanological or petrological studies, and various other disciplines and topics from the other projects such as PAGES, INTIMATE and so on. Keynote speakers will be up to date in INTAV-J Home Page as soon as possible, so please check it out at times.
