Dubbed the Kikai caldera, this mostly-underwater caldera located south of Japan’s Ryuku Islands last erupted 7,300 years ago, marking the largest volcanic eruption in the current geological epoch, the Holocene.

Researchers discovered that massive lava flows and collapsing lava ponds at Axial Seamount reveal how underwater eruptions reshape the seafloor.

Spread the loveIntroduction In a remarkable advancement in our understanding of underwater geology, researchers have made significant discoveries at Axial Seamount, an active underwater volcano located off the coast of Oregon.

An underwater volcano off the Oregon coast could erupt late this year, scientists say. The volcano, known as Axial Seamount, is more than 4,900 feet beneath the Pacific Ocean and 300 miles off the Oregon coast, but it is showing signs it will soon erupt ...

The Kikai Caldera. (Seama Nobukazu/CC BY 4.0) About 7,300 years ago, a volcano off Japan's Kyushu island unleashed what remains the largest known eruption of the Holocene, our current geological epoch.

Scientists are predicting that a mile-long volcano off the U.S. West Coast will erupt this year. The Axial Seamount, an underwater volcano located about 300 miles off the coast of Oregon, is displaying behavior that indicates an eruption is imminent in ...

Far beneath the ocean near Japan, scientists have discovered that the magma system linked to the most powerful eruption of the Holocene is slowly rebuilding. By using seismic imaging, researchers mapped a large magma reservoir under the Kikai caldera and confirmed it is the same system that fueled the massive eruption 7,

A new study reveals that Japan's Kikai Caldera is gradually refilling with fresh magma, offering key insights into volcanic eruption cycles and future risk prediction.
