Tsunami risk in the Aegean: threat assessment and preparedness measures. The old harbour on Santorini is closed for months and the island prioritises safety during the tourist season.
Potential for the occurrence of a tsunami between the islands of Santorini and Amorgos
Recent research from Greek scientists has highlighted the potential for a tsunami to occur in the central Aegean region, particularly between the islands of Santorini and Amorgos.
The study, conducted by experts at the National and Kapodistrian University of Athens, indicates that while earthquakes are a common cause, other factors like underwater and on-land landslides could also trigger devastating waves.
This underscores the importance of being prepared and fostering public awareness about tsunami risks in the area.
Greece, with its significant seismic activity, faces a continual threat of tsunamis.
The research team asserts that this risk is not confined to recent seismic events but remains a constant concern.
The need for a well-structured evacuation plan, clear guidelines, and ongoing public training is essential to reduce potential risks.
To this end, the NKUA team has meticulously mapped areas prone to tsunami risks and evaluated the adequacy of existing refuge points established by local authorities.
Key Findings on Tsunami Risk in the Aegean
The Aegean Sea is a geologically active region, making it susceptible to tsunami hazards linked to earthquakes and volcanic eruptions.
Several coastal areas, including prominent Greek islands such as Santorini and Amorgos, have designated refuge zones.
For instance, on Santorini, safe points are located approximately 3,100m to 3,200m from the coast, providing some protection, but they may limit quick escape during emergencies.
In contrast, Ios has designated sites like Chrysi Akti, which are prone to flooding even with a low tsunami run-up of 0-3m.
Naxos presents challenges with many marked refuge areas situated within high-risk zones due to its urban density, necessitating an assessment of safer evacuation routes.
Such findings underscore the importance of hazard assessments in these coastal areas.
Necessity for Enhanced Preparedness Measures
Addressing the threat of tsunamis demands urgent and comprehensive preparedness actions. Key strategies include:
- Updating refuge areas to ensure they remain suitable and safe.
- Establishing clear evacuation zones and marked escape routes to guide the public during emergencies.
- Enhancing public awareness through educational initiatives aimed at both residents and tourists regarding tsunami risks and safety measures.
- Conducting regular preparedness drills involving the community, local authorities, and emergency services to ensure a coordinated response.
- Improving scientific surveillance of seismic activity and reinforcing the early warning system to provide timely alerts.
As climate change escalates the threat of tsunamis, prioritising such measures is essential to protect lives and infrastructure in vulnerable regions like the Cyclades.
Old harbour on Santorini closed for months
The old harbour below Fira on Santorini has been declared closed for a period of two to three months. This decision has been made due to safety concerns following recent seismic activity in the area.
The closure means that no cruise ships will be able to dock at this harbour during this time.
Officials are keen on ensuring the safety of both residents and visitors, as the island seeks to protect its reputation as a popular tourist destination.
Tourism Minister Olga Kefalogianni highlighted the importance of maintaining the island’s image.
She stated that Santorini is a major brand in tourism, and it is essential for all stakeholders to work together to ensure visitors feel safe.
The government is closely monitoring seismic data to assess the ongoing risk to the area.
Various safety measures have been introduced, reflecting the commitment to providing a secure environment for guests.
Santorini Prioritises Safety for the Tourist Season
In light of recent seismic activity, Santorini is preparing for the upcoming tourism season with a clear focus on safety measures.
Authorities have conducted thorough inspections of educational and commercial buildings, ensuring they are deemed structurally sound.
Repairs are currently in progress to meet enhanced safety regulations, and both residents and tourists are receiving detailed information on emergency preparedness.
Building Confidence After Natural Events
Santorini, known for its breathtaking sunsets, is declaring its readiness for the bustling tourist season after facing weeks of seismic unrest.
Many locals and visitors temporarily left their homes in cliffside villas due to concerns over safety.
Officials are now reinforcing their commitment to prioritising safety, standing firm against any doubts that may linger.
The Organisation for Earthquake Planning and Protection (OASP) and KTYP S.A. have inspected various public buildings and schools.
Their findings indicate that the structural integrity of most inspected buildings remains stable, with the majority classified within the highest safety tiers, A and B.
This means these structures are well-equipped to endure further seismic events, providing reassurance to both locals and tourists alike.
Ongoing repairs are being made to those buildings rated B, which involve vital maintenance like reinforcing walls and securing fixtures.
Local officials emphasise their dedication to safeguarding the wellbeing of students and educators as their foremost concern.
Preparedness Amid Ongoing Tremors
The recent seismic disturbances originated from underwater tremors close to the island’s volcanic core.
While many residents managed to stay calm, thousands opted to relocate temporarily to nearby islands such as Anafi and Ios, drawn by their peaceful surroundings amidst the tremors.
As the seismic activity begins to stabilise, Santorini’s daily activities are returning to normal.
Schools resumed operations with strict safety protocols in place, guiding both staff and students on emergency procedures.
These measures include detailed evacuation strategies and addressing potential hazards, ensuring preparedness in the case of future tremors.
A comprehensive guide for residents and visitors has been updated, providing important safety tips.
Among the key recommendations are:
- Avoid abandoned structures: These areas can pose risks.
- Stick to safer paths: Some routes may be hazardous due to landslide potential.
- Evacuate coastal areas promptly: If a stronger quake occurs, swift action is essential.
- Secure belongings: Check homes and businesses for unstable items.
- Assess swimming pools: If a pool seems unsafe, draining it is advisable.
Officials understand that many visitors may still be tempted to venture into risky areas for photographs, prompting these clear directives.
Stability and Plans for the Future
Santorini’s Deputy Mayor for Civil Protection has reiterated that ongoing safety measures are vital.
Some regions remain off-limits to ensure extra protection, particularly in high-risk areas.
Nonetheless, authorities maintain that proactive steps are effectively enhancing safety.
The government’s focus extends beyond immediate responses to seismic activity.
Plans for long-term improvements in infrastructure are now a high priority, indicating that Santorini is not merely reacting but proactively preparing for any eventualities associated with its volcanic context.
Tourists visiting Santorini can take comfort knowing engineers and planners are ensuring a stable environment.
These preparations are viewed as a long-term commitment to safety rather than a temporary solution.

How probable is a tsunami in the Mediterranean Sea?
Tsunamis are possible in the Mediterranean Sea, though they occur less frequently than in other regions like the Pacific Ocean.
The geological features and tectonic activity in the area can generate tsunamis, but they are generally less common.
Which areas in Greece face the highest tsunami risk?
Regions in Greece, especially those close to seismic zones like the Aegean Sea, are at greater risk.
Islands such as Santorini and Crete are considered more vulnerable due to their geological settings and close proximity to tectonic plate boundaries.
Has there been a noticeable rise in tsunami occurrences in the Aegean Sea recently?
Recent studies suggest that although there have been instances of tsunamis in this region, there has not been a significant uptick in activity.
The historical record shows sporadic tsunami events, but no alarming trend has been identified in the short term.
How does Greece’s tsunami warning system function?
Greece operates a tsunami warning system that monitors seismic activity and potential tsunami threats.
