For Joint events, the second letter indicates the Lead Association (with the abbreviations listed below) and the third indicates whether a session is a Symposium (S) or a Workshop (W). In some cases (namely IAGA, IAHS) Association session codes have an extra codi. cation referring to a speci. c Theme or Division. U UNION J JOINT G IAG A IAGA H IAHS M IAMAS P IAPSO S IASPEI V IAVCEI Some examples: US002 is a Union Symposium; JGW001 is a Joint IAG Workshop with IAG as the Lead Association; MS003 is an Association (IAMAS) Symposium. AS III 020 is an Association (IAGA) Symposium sponsored by its III Division.

Methods for prediction and hazar d asse ssment. Sediment- laden gravity flows are common occurrences in vo lcanic settings, where t hey prese nt widespread an d co ntinuing risk to huma n settlements and life. Sediment-laden gravity flows are initiated by various mechanisms, among which the most common are intense and/or prolonged precipitation, breakouts of crater lakes, melting of snow or glacial ice during an eruption, or seis mic trigge ring of landslides that evolve to debris flows. Volcaniclastic mass flows ca n be generated both during or shortly
