Magma accumulation in Japan's Kikai caldera

Overview

Scientific research and seismic surveys have identified that fresh magma is accumulating beneath the Kikai caldera, located south of Kyushu island, Japan. This volcanic system was responsible for the Kikai-Akahoya eruption approximately 7,300 years ago, one of the most powerful volcanic events of the Holocene.

Studies indicate that while the prehistoric eruption caused widespread destruction through tsunamis, ashfall, and pyroclastic flows, the impact on human populations was uneven. Archaeological evidence suggests that while many settlements were abandoned, certain Jōmon hunter-gatherer communities survived by migrating to northern Kyushu.

Researchers from Kobe University and other institutions note that while the detection of a potential magma reservoir provides insight into how supervolcanoes rebuild their supplies, it does not imply an imminent eruption. Further data is needed to determine the exact composition of the reservoir, specifically the ratio of molten to crystallized material.

    Kikai caldera research reveals magma accumulation in Japan

    Seismic studies of Japan's Kikai caldera show magma has accumulated since a massive volcanic eruption 7,300 years ago, though experts state an eruption is not imminent.

    Kikai supervolcano in Japan is refilling with fresh magma

    Researchers have found that magma is refilling Japan's Kikai caldera, a supervolcano that erupted 7,300 years ago. The discovery aids understanding of how massive volcanic systems rebuild.
