Greek Island Volcano: Eruption Threat?

by Alexandra Hartman Editor-in-Chief
written by Alexandra Hartman Editor-in-Chief

New Research Aims to Predict santorini VolcanoS Next Eruption

SANTORINI, Greece — The picturesque island of Santorini, famed for its stunning white-washed villages perched atop dramatic cliffs, attracts millions of tourists each year.However, beneath this idyllic facade lies a potentially devastating secret: an active volcano simmering beneath the Aegean Sea.

Now, an international team of scientists is embarking on a groundbreaking mission to assess the true danger posed by Santorini’s underwater volcanic activity adn to better predict the potential for future eruptions.

Just weeks ago, seismic activity rattled the island, prompting nearly half of santorini’s 11,000 residents to flee. The earthquakes served as a stark reminder of the volatile tectonic forces at play beneath the popular vacation destination, where the African and Eurasian plates meet.

Aboard the British Royal Research Ship Discovery, researchers are employing cutting-edge technology to study the caldera, the vast crater formed by an ancient, cataclysmic eruption that shaped Santorini’s iconic horseshoe shape. the research is focused on the hydrothermal vents surrounding the volcano, cracks in the Earth’s crust on the seafloor that release superheated water and gases.

“It’s a bit like ‘out of sight, out of mind’ in terms of understanding their danger, compared to more famous ones like Vesuvius,” said Professor Isobel Yeo, a submarine volcano expert, wiht Britain’s National Oceanography Center, underscoring the relative lack of attention given to underwater volcanoes compared to their terrestrial counterparts. Yeo leads the Discovery mission,which includes 22 scientists from around the world.

The team is using a remotely operated vehicle (ROV),a car-sized robot,to descend to depths of 300 meters (nearly 1,000 feet) to collect samples of fluids,gases,and rocks from the hydrothermal vents. Thes vents transform the seabed into an otherworldly landscape of orange-hued formations and plumes of gas. The analysis of these samples could provide critical insights into the volcano’s activity and potential for eruption.

One of the key questions the scientists are trying to answer is whether the interaction between seawater and magma within these hydrothermal systems makes a volcano more or less explosive. The composition and behavior of these underwater vents remain largely unknown, with Yeo noting, “We know more about the surface of some planets than what’s down there.”

Santorini’s most recent eruption occurred in 1950, but a period of unrest in 2012, during which magma flowed into the volcano’s chambers and caused the island to swell, demonstrated the ever-present threat.The research is especially relevant in light of recent events, such as the 2022 Hunga Tonga-Hunga Ha’apai eruption in the Pacific Ocean. That underwater explosion ranked as the largest ever recorded and triggered a tsunami that reached the Atlantic, with shockwaves felt as far away as the United Kingdom. The devastating impact on nearby islands in Tonga, some of which remain uninhabited to this day, highlights the destructive power of submarine volcanoes.Along with studying Santorini’s caldera, the Discovery is also venturing to Kolumbo, another major volcano located just 7 kilometers (4.3 miles) northeast of the island. While an imminent eruption is not expected at either location, scientists emphasize that it is indeed only a matter of time.

professor Paraskevi nomikou, a geologist from Santorini, is part of the government emergency group that met daily during the recent earthquake crisis. She is particularly invested in translating the research findings into practical measures for the local community.

“This research is very important because it will inform local people how active the volcanoes are, and it will map the area that will be forbidden to access during an eruption,” said Nomikou, whose childhood experiences with earthquakes and eruptions inspired her career.

The data collected during the expedition will be used to create detailed geohazard maps for Greece’s Civil Protection Agency. These maps will identify areas at greatest risk during a potential eruption, helping local authorities prepare and respond effectively to future volcanic events. This work will help forecast potential hazards arising from underwater volcanoes globally, said Yeo.

We dive deep into the ongoing research aimed at predicting future eruptions in the santorini region, a critical endeavor for the safety of locals and the millions of tourists who visit this iconic Greek island annually.

the Risks of Santorini: An underwater Volcano

Archyde News: Dr.Vrontou, thank you for joining us. Could you start by explaining the unique challenges involved in studying an underwater volcano like the one beneath Santorini?

Dr. Vrontou: Thank you for having me. The primary challenge is accessibility. Unlike terrestrial volcanoes, we can’t simply hike up and take samples.We use remotely operated vehicles (ROVs) like those deployed by the team on the research ship Discovery. This means navigating deep underwater, collecting samples from hydrothermal vents, and gathering data in a very remote surroundings.

Unveiling the Secrets of Hydrothermal Vents

Archyde News: The research focuses heavily on hydrothermal vents. Why are these features so critical to understanding the volcanic activity?

Dr. Vrontou: Hydrothermal vents are essentially cracks in the Earth’s crust where superheated water and gases are released.They’re like windows into the volcano’s inner workings. Analyzing the fluids and gases from these vents – their chemical composition, temperature, and flow rate – gives us crucial insights into the behavior of the magma chamber and potential for an eruption.

The connection Between Magma and seawater

Archyde News: One of the key questions, as we understand it, is whether the interaction between seawater and magma makes a volcano more or less explosive. Could you elaborate on this?

Dr. Vrontou: It’s a crucial aspect of our research. The presence of water substantially impacts volcanic eruptions. When magma interacts with water, it can lead to highly explosive events. Understanding the specifics of this interaction within Santorini’s volcanic system is critical for predicting future eruption styles and intensities.

Data and Prediction: Informing Local Communities

Archyde News: How will this research translate into practical measures for the people of Santorini?

Dr. Vrontou: The data collected will be used to create detailed geohazard maps. These maps will identify areas most at risk during a potential eruption. This details will be crucial for the Greek Civil Protection Agency to prepare and respond effectively, including evacuation planning and establishing safety zones. The goal is to give local authorities actionable intelligence to protect the community.

Looking Beyond Santorini

Archyde News: Beyond Santorini,what broader implications does this research hold for volcanology globally?

Dr. Vrontou: The lessons we learn here can be applied to other submarine volcanoes. The research on Santorini offers a unique opportunity to gain deep insight into underwater eruption cycles, with the potential to create safer, more accurate prediction models for global volcanic activity, and inform safety measures around the globe. What we learn is incredibly relevant to similar regions around the world.

A Question for Readers

Archyde News: Considering the devastating impact on the pacific region with the Hunga Tonga-Hunga Ha’apai eruption, what key questions do you think more research needs to answer about submarine volcanic activity?

Skewed Subduction Shear Zones – Eos

by Alexandra Hartman Editor-in-Chief
written by Alexandra Hartman Editor-in-Chief

Subduction Zone Obliquity Shapes Overriding Plate Deformation

Table of Contents

Convergent plate boundaries, where one tectonic plate subducts beneath another, often exhibit curved geometries. This bending and curving is a result of complex interactions between factors such as topography, sediment transport, plate interface strength, and deep slab dynamics. These bends and cusps significantly influence both long-term fault movements and the patterns of earthquakes along these boundaries.A recent study published in AGU Advances provides new insights into how the angle between the colliding plates, known as obliquity, affects the deformation of the overriding plate. Examining both geodetic (earth’s surface movement) and geological timescale constraints, the researchers found a consistent pattern of deformation across different timescales, irrespective of the obliquity.

“These findings have notable implications for understanding how strain energy is distributed and potentially dissipated within the plate tectonic system,” says Thorsten Becker, Editor of AGU Advances. “While a complete theory is still lacking, this study offers new insights into the physics of transpressional systems, including the evolution of shear zone strength and fault system interactions.”

“It has long been recognized that the degree to which deformation in the overriding plate is partitioned into translation and rotation is strongly influenced by this obliquity,” says led author Katherine morell. “Though, this comparative analysis reveals that overriding plate deformation patterns remain remarkably consistent across different timescales, with no clear threshold obliquity value governing partitioning.”

The study suggests that strain energy distribution within plate tectonic systems is complex and may not be directly linked to the angle of subduction. This opens up new avenues for research into the long-term evolution of subduction zones and the resulting seismic activity.

Practical Applications:

Understanding the relationship between obliquity and overriding plate deformation has implications for various fields, including:

Earthquake prediction: Identifying areas with potentially high strain accumulation due to specific obliquities could help improve earthquake hazard assessments.
 Resource exploration: Subduction zones often host valuable mineral deposits. Understanding the influence of obliquity on deformation patterns can aid in identifying potentially rich areas.
Geothermal energy:

The heat generated by subduction zones can be harnessed for geothermal energy production. understanding how obliquity affects this energy distribution can optimize geothermal resource development.

Morell et al. (2025) suggest that future research should focus on:

Developing a more comprehensive theory to explain the observed patterns of overriding plate deformation.
* investigating the role of material properties and rheology in influencing deformation.

Understanding the complex interplay of forces shaping these dynamic geological features is crucial for mitigating natural hazards, exploring natural resources, and advancing our knowledge of earth’s processes.

How might the findings in Dr. Morell’s study impact earthquake hazard assessments?

architectural interview

Obliquity’s Role in Overriding Plate Deformation: A Conversation with Katherine Morell

Archie News Editor: Today we have with us Dr. Katherine Morell, a distinguished geophysicist and lead author of the recent study published in AGU Advances, exploring the influence of obliquity on overriding plate deformation. Welcome, Dr. Morell!

Katherine morell:

Thank you, glad to be here.

Archie News Editor:

Yoru study challenges the long-standing belief that obliquity directly governs partitioning of deformation in the overriding plate. Could you walk us through your findings?

morell:

Our comparative analysis of geodetic and geological data from various subduction zones revealed a consistent deformation pattern across different timescales.Contrary to previous assumptions, we found no clear threshold obliquity value that dictates partitioning of deformation into translation and rotation.

Archie News Editor:

So, how does obliquity influence the overriding plate’s deformation if not through partitioning?

Morell:

while obliquity does influence strain energy distribution, our study suggests that it’s more complex than previously thought. The disturbance might not be directly linked to the angle of subduction. This opens up avenues for further research into long-term subduction zone evolution and seismicity.

Archie News Editor:

What are the practical implications of your findings?

Morell:

Understanding the relationship between obliquity and overriding plate deformation can improve earthquake hazard assessments, aid resource exploration in subduction zones, and optimize geothermal energy development.

Archie News Editor:

Your study calls for a more extensive theory to explain these observed patterns. What are the key aspects researchers should focus on?

Morell:

Indeed, we need to delve deeper into the role of material properties and rheology in influencing deformation patterns. Additionally, diverse data sets and interdisciplinary collaborations will be crucial to develop a more holistic understanding of these complex geological systems.

Archie News Editor:

Dr. Morell, what keeps you awake at night when thinking about plate tectonics?

Morell:

Frankly, it’s the unknowns – the parts of our planet we’ve yet to explore, and the processes we haven’t fully understood.I’m driven by the desire to unravel these mysteries and contribute to our knowledge of Earth’s dynamics.

Archie News Editor: Thank you, Dr.Morell, for sharing your insights. Your work undoubtedly contributes to our understanding of the complex dance of tectonic plates.

For our readers, what’s the next step in this research journey?

Morell:

Encouragingly, several research groups are already building on our findings. I’m excited to see what new discoveries emerge as we continue to unravel the intricate mechanics of subduction zones.
