Tephrabase contains data on sites where tephra layers have been found from Iceland, the British and Irish Isles, Scandinavia, northern Europe and across into Russia.
There are a several ways to search the database. Four groups of searches can be accessed from this page including location, geochemistry, date and volcanic systems/eruptions. These searches now integrate the Laacher See Tephra, which was perviosuly accessed separately.
