TEPHRA-SAMPLING PROTOCOL

A protocol for tephra sampling is necessary to obtain comparable datasets and to have good data to characterize the deposit as well as run computer simulations. Such a protocol should include standard techniques for:

1) tephra sampling for the compilation of isopach and isomass maps (thickness and mass/area)

2) tephra sampling for grain-size analysis

3) collection and measurement of the largest clasts for the determination of column height and wind speed at the time of the eruption

These techniques were discussed during our third meeting and particular attention was given to the collection of the largest clasts.
