Beneath the azure waves of the Aegean Sea, researchers are delving into the mysteries of Kolumbo, an underwater volcano close to Santorini. Recent investigations led by the University of Athens and the Hellenic Center for Marine Research (HCMR) have uncovered groundbreaking insights into this risky big. Through two pioneering analysis applications, Santory and Thira, scientists deployed subtle gear into Kolumbo’s 500-meter-deep crater to watch its exercise and create detailed time sequence information, a primary for this volcano.
The research confirmed Kolumbo’s excessive exercise ranges. State-of-the-art instruments, together with sensors measuring temperature, strain, pH, CO₂, hydrogen sulfide, and turbidity, recorded vital findings. Cameras captured vivid visuals of hydrothermal chimneys venting fluids at a scorching 230C, wealthy with carbon dioxide. Active hydrothermal techniques like this demand fixed monitoring, as adjustments in emissions might sign eruptive conduct, in response to Professor Evi Nomikou, head of the Santory undertaking.
The work additionally included seismographs and inclinometer measurements that allowed scientists to trace underwater currents and tectonic shifts. A parallel mission and in cooperation with Santory, Multi-Marex, backed by German funding, is ready to deploy 26 underwater seismographs within the coronary heart of the volcano. At the identical time, a 3D seismic imaging can be carried out on the Amorgos fault, which prompted a catastrophic 1956 earthquake.
The findings aren’t confined to scientific circles. The Thira initiative introduced volcanic consciousness into Santorini’s faculties, fostering a deeper understanding of volcanic hazards in a group residing close to Kolumbo. While municipal funding has lapsed, researchers advocate continued assist to make sure the information stream aids long-term volcanic monitoring.
Kolumbo exemplifies how cutting-edge know-how, worldwide collaboration, and native engagement can converge to light up the complexities of the Earth’s risky undersea landscapes, safeguarding each information and lives.
