*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.
