the Osumi Islands, where the Kikai caldera is located. <span class=\"credit\">Peter Hermes Furian \u2013 stock.adobe.com<\/span><\/figcaption><\/figure>\n<p>Over the last 3,900 years, a new lava dome has been forming beneath the 12-mile-wide caldera, sparking fears of a sequel. And while the caldera hasn\u2019t done anything as bombastic since, there has been scattered volcanic activity with researchers noting that even a modest eruption could prove devastating.<\/p>\n<p>To get to the bottom of the combustive phenomenon, the researchers dispatched research boats to scan the area with air-guns and seismometers that were planted on the sea floor.<\/p>\n<p>Using these tools, they were able to measure how the pulses traveled through the Earth\u2019s crust, discovering a large lava reservoir that seemingly supplied Akahoya.<\/p>\n<aside class=\"single__inline-module alignleft\">\n\t<\/aside>\n<p>Unlike with the last blast, however, this lava was all new material. <\/p>\n<p>Chemical analyses revealed that the material and other recent activity was comprised of different magma than what was expelled during the last eruption, meaning that the reservoir has been infused with newly-injected molten rock.<\/p>\n<p>In fact, Nobukazu found that this \u201cmagma re-injection model\u201d mirrored other \u201clarge shallow magma reservoirs\u201d such as the one beneath Yellowstone. Scientists have long feared that this caldera could potentially lead to human extinction, although studies have suggested that this <a href=\"https:\/\/www.scientificamerican.com\/blog\/rosetta-stones\/will-yellowstone-erupt-soon-and-kill-us-all\/\" target=\"_blank\" rel=\"noopener\">concern is grossly overblown.<\/a><\/p>\n<p>Nonetheless, the findings could help inform future models of how magma reservoirs under caldera volcanoes refill following major eruptions. <\/p>\n<p>This would, in turn, help volcanologists better predict if and when a volcano\u2019s going to blow its stack.<\/p>\n<p>\u201cWe want to refine the methods that have proved to be so useful in this study to more deeply understand the re-injection processes,\u201d said Nobukazu. \u201cOur ultimate goal is to become better able to monitor the crucial indicators of future giant eruptions.\u201d<\/p>\n<\/p><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/nypost.com\/2026\/04\/09\/science\/explosive-kikai-volcano-refills-with-lava-sparking-eruption-fears\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This situation is heating up.
