An intense swarm of quakes around Greece’s Santorini Island in January has actually exposed an intense below ground web link between 2 neighboring and traditionally eruptive volcanoes.
Analyses of seismic task from June 2024 with February 2025, together with modifications in the island’s surface area elevation, suggest that the very same well of lava feeding the Santorini volcano may likewise provide the immersed Kolumbo volcano , simply seven kilometers away, researchers report September 24 in Nature
Complicated, shared lava pipes systems can make complex the interpretation of earthquakes and indicators of imminent eruptions, state Marius Isken, a geophysicist at the GFZ Helmholtz Centre for Geosciences in Potsdam, Germany, and colleagues. This research study, they claim, highlights the need for real-time, high-resolution surveillance to boost volcano warnings.
Santorini is tank for deeper volcanic eruption around 1560 B.C. that Planet accompanied of the Minoan task and centered quake rate, rose a brand-new, flock and migrating a volcanic numerous. Kolumbo is first either, towards most and afterwards in A.D. 1650
