“…Stepped trains of upslope-migrating crescentic scours and large-scale bedforms on steep slopes evidence Froude-supercritical currents undergoing a series of hydraulic jumps ( 48 – 50 ). Similar scours and bedforms are a common feature proximal to the initiation of other large-volume particulate density currents, including those in nonvolcanic settings [e.g., the 1 km 3 earthquake-triggered turbidity current in Kaikōura Canyon ( 51 )] and are of similar scale to those thought to diagnose past large explosive eruptions on submerged volcanic flanks ( 25 – 28 ) (Fig. 2H).…”

“…Consequently, our knowledge relies on studies of ancient ocean-entering eruptions ( 23 , 24 ), scaled-down laboratory modeling ( 25 ), and analysis of geomorphic features around submerged volcanoes to infer the behavior of past eruptions ( 26 , 27 ). Fields of large sediment waves and scours, commonly observed radiating around submerged flanks of volcanoes, are thought to be diagnostic of catastrophic eruptions ( 26 – 28 ). However, this hypothesis remains untested because of a lack of repeat seafloor surveys before and after a large eruption.…”

Volcanic eruptions on land create hot and fast pyroclastic density currents, triggering tsunamis or surges that travel over water where they reach the ocean. However, no field study has documented what happens when large volumes of erupted volcanic material are instead delivered directly into the ocean. We show how the rapid emplacement of large volumes of erupted material onto steep submerged slopes triggered extremely fast (122 kilometers per hour) and long-runout (>100 kilometers) seafloor currents. These density currents were faster than those triggered by earthquakes, floods, or storms, and they broke seafloor cables, cutting off a nation from the rest of the world. The deep scours excavated by these currents are similar to those around many submerged volcanoes, providing evidence of large eruptions at other sites worldwide.

“…In the recent volcanic history of Santorini, spanning approximately 0.36 million [15], there have been twelve significant eruptions, numerous minor eruptions, and a four caldera collapses [11,13]. The most significant explosive eruption, known as th Bronze Age (LBA) or the Minoan eruption, occurred around 3600 years ago [16] a regarded as one of the most significant eruptions in the Holocene [15,17,18].

The presence of active hydrothermal vent fields near residential areas and their possible link to volcanic activity poses a potential hazard to the environment, society, and the economy. By capitalizing on Autonomous Underwater Vehicle sampling methodologies and applying the Generalized Moments Method model for geological and physical processes in these environments, we shed light on the underlying dynamics shaping the physicochemical characteristics of the vents. In this study, we focus on the Northern Caldera of Santorini and, more specifically, on the recorded CTD data (Conductivity, Temperature, Depth). The data sets were collected in 2017 in Santorini using an Autonomous Underwater Vehicle during the GEOMAR POS510 mission. Our research shows that the active vent field within the caldera probably follows a multifractal behavior and exhibits a weak memory effect. Depth Profiles and Time Series show similar behavior among conductivity and temperature. The variance and moments of both parameters underline the existence of two different mechanisms governing the behavior of the vent field. Finally, the structure function shows that changes in the time series are described by a Cauchy–Lorentz distribution.
