The sedimentary layer of ejecta from the eruption at the end of the 7th century is called ao-kora (ao means blue and kora is soil consisting of volcanic ash found in the southern part of the Satsuma Peninsula). The sedimentary layer of ejecta by the eruption at the end of the 7th century is called murasaki-kora (Murasaki means purple). These layers are a clue to know the changes in life in this era. It has become clear that a village was isolated by a large eruption with change in life style in the latter part of the 9th century.
