*Note that the Tephra layer depth of a cryptotephra does not indicate the thickness of the layer, as in a visible tephra tephra layer. The thickness indicates the spread of the tephra shards in the sediment or sometimes the top and bottom depths are the same (i.e. no apparent thickness).

1Correlated tephra name means that the tephra deposit has been correlated with a tephra horizon found at multiple sites (e.g. Hekla 4). Of course, these correlations could be reinterpreted and care needs to be taken.

2Local tephra name is the name given by the researchers for the tephra found at the site, this is often a mixture of a site code/name and the depth of the tephra. Not all tephra layers in Tephrabase have a local name, but more or being added. This is independent of any correlations to other tephra deposits.
