"'Due to its extent and location it is clear that this is in fact the same magma reservoir as in the previous eruption,' geophysicist Professor Seama Nobukazu said."
"'We must understand how such large quantities of magma can accumulate to understand how giant caldera eruptions occur.'"
"During the previous Kikai eruption, around 36 cubic miles (160 cubic kilometres) of dense rock was spewed across 1,700 square miles (4,500 square kilometres)."
"Chemical analysis showed that the material produced by this and other recent volcanic activity is of a different composition than what was ejected during the last eruption."
The Kikai volcano, which last erupted 7,300 years ago, is showing signs of activity as its magma reservoir has been refilling for 3,900 years. Researchers have observed steam emissions and small earthquakes in the area. The previous eruption was catastrophic, ejecting vast amounts of magma and affecting the Jomon civilization. Current studies using seismic waves have confirmed the reservoir's size and that it is accumulating fresh magma, indicating the volcano remains active and poses a potential threat of another eruption.
