Eventually, as is the way of the world, gravity wins out and the tephra falls to the ground.

Tephra and Tephrochonology

Some of it, the stuff we are interested in, falls on bogs! This might not sound so special, but it helps us in our studies for several key reasons.

The first is that the geochemistry, or what elements the tephra is made up of and in what proportions, is unique to each volcano and each eruption. So by analysing the geochemistry, we can tell the difference between the tephra from different volcanoes. We can even tell the difference between tephra from two different eruptions of the same volcano. But we can treat samples of the peat in a lab in such a way burning it in a furnace then rinsing with weak acid — please do not try this at home!

Tephrochronology is the word we use to describe the use of these tephra layers as a chronological tool — meaning a tool that helps us to date our cores. For example, say there are historically documented records of a volcanic eruption in a given year. An example we have found before is the eruption of the Icelandic volcano Askja in If we find a tephra layer in our core, analyse the geochemistry and find it is the same as that Askja eruption, we can then apply the date of to the depth that we found it.
