COResearchers at Kobe University have detected new internal activity beneath the submerged Kikai Caldera in southern Japan, which was responsible for the largest eruption in the last 11,700 years. The study reveals that the caldera is accumulating large volumes of molten material within the same structures that caused a catastrophic event 7,300 years ago. Using advanced seismic technology, scientists mapped the area by sending controlled air pulses through the rock and measuring changes in wave speed with sensors on the ocean floor. The findings indicate that the magma reservoir under the caldera is being actively replenished, with new material forming a lava dome over the past 3,900 years. This suggests that the current magma is newly injected rather than remnants from the ancient eruption.
