Further mass exodus yesterday from Santorini after earthquake wave. Continuous tremors during the night, the strongest with a magnitude of 4.1 Richter.
Seismic Activity and Research Updates in Santorini Region
Residents Continue to Leave Santorini
The ongoing seismic activity in the Cyclades, particularly around Santorini, has raised significant concern among residents and visitors alike. As the region experiences a flurry of tremors measuring between 2.7 and 4.9 on the Richter scale, yesterday again many individuals are choosing to leave the island.
This mass departure is evident as ports and airports see heightened activity, with numerous ferries and flights now fully booked. Many families have sought refuge in designated shelters due to the uncertainty surrounding the situation.
Experts are analysing the recent earthquake patterns and have expressed cautious optimism. They believe that while the seismic activity remains a concern, the likelihood of a larger quake is decreasing.
Scientists advise patience in assessing the situation, as it may take some time before clearer conclusions can be drawn.
As the community navigates this challenging period, the response from both local authorities and individuals reflects a commitment to safety and careful monitoring of developments.
The 5.2 Magnitude Quake May Have Been the Main Event
Gerasimos Papadopoulos, a prominent seismologist, noted that the 5.2 magnitude earthquake that struck on February 5th could potentially be the main shock.
He observed a notable decrease in the magnitudes of subsequent earthquakes as a key indicator of this possibility.
Following the initial tremor, the smaller aftershocks prompted a reassessment of the seismic activity in the region.
In a recent update shared on social media, Papadopoulos discussed the seismic events occurring in the Santorini-Amorgos area.
He referenced a preliminary report published by the European-Mediterranean Seismological Centre, which provided insights into the patterns of seismic activity following the main earthquake.
The report indicated that the intensity of aftershocks has diminished, suggesting that the 5.2 quake may represent the strongest release of energy for the time being.
Key Observations
- Magnitude Drop: A significant reduction in the strength of aftershocks was noted after the magnitude 5.2 earthquake.
- Preliminary Report: The initial report from the European-Mediterranean Seismological Centre confirmed the ongoing seismic sequence in the affected area.
- Further Research Needed: Papadopoulos emphasised the need for further analysis to confirm whether the 5.2 quake is indeed the main shock.
Implications of Findings
Papadopoulos indicated that while the reduction in aftershock magnitudes is a positive sign, it is still too early to draw definitive conclusions.
The uncertainty surrounding seismic events means that continued monitoring and research are critical.
Community Impact
The seismic activity has raised concerns among local residents and authorities.
Awareness of earthquake safety measures and preparedness is crucial, especially in regions prone to seismic events.
Educational initiatives about what to do during an earthquake can help reduce risk and improve community response.
Seismology plays an essential role in understanding such natural events. The data gathered during these occurrences can significantly contribute to forecasting and mitigating future risks.
Papadopoulos has been at the forefront of these efforts, dedicating his expertise to ensure that accurate information is shared with both the scientific community and the public.
Future Predictions
As studies on the seismic sequence in Santorini continue, experts will be keeping a close eye on any emerging patterns.
The research community will focus on understanding the nature of the seismicity and the relationship between the main shocks and aftershocks.
Positive Messages
Currently, the outlook regarding the phenomenon in Santorini is optimistic, according to Professor of Geophysics and Seismology at Aristotle University of Thessaloniki, Kostas Papazachos.
In a recent interview with SKAI, he expressed that recent developments indicate improvement. He noted that the situation seems to be getting “better” in the days leading up to his statement.
However, he also emphasised the unpredictable nature of geological events.
While the signs show a trend towards stabilisation, it is crucial to remain vigilant since nature can present unforeseen challenges.
Reduced Seismic Activity, Lower Risk of 6 Magnitude Quakes
Recent assessments indicate a significant shift in the expectations regarding seismic activity in certain regions.
According to the president of the Earthquake Planning and Protection Organisation, Efthymios Lekkas, the scenario predicting a strong earthquake of magnitude 6 or higher has been revised.
It now appears that the likelihood of experiencing earthquakes of 6, 6.1, or 6.2 magnitude has substantially decreased.
Authorities are convening today to discuss the latest developments.
The committees focused on seismic and volcanic risks will analyse new data and consider appropriate recommendations for the state.
This effort illustrates the ongoing commitment to public safety and disaster preparedness in seismically active regions.
Lekkas emphasised that the potential for an earthquake of 6 magnitude or more is significantly lower than previously thought.
He pointed out that energy accumulation in the area is steadily decreasing. “Today, we feel a bit more optimistic than we did yesterday,” he stated, reflecting a positive outlook regarding ongoing seismic activity and its implications.
The focus on seismic sequences and the associated underwater faults plays a vital role in understanding earthquake risks.
These zones often exhibit complex interactions that can influence ground movements and affect local communities.
Lekkas noted that monitoring these factors is essential for assessing the potential for future seismic events.
The caldera in Santorini remains a point of interest due to its geological history.
Historically, the caldera has been tied to volcanic activity, which can influence the surrounding seismic landscape.
As the situation evolves, continuous monitoring will help provide clarity about any potential volcanic threats in the region.
Understanding the interplay between volcanic and seismic activity is crucial for developing effective strategies to mitigate risks.
The current assessment suggests that while seismic activity will continue, the immediate risk of a significant earthquake remains low.
This development allows for a more informed approach to managing public safety.
Key considerations include:
- Reduced likelihood of earthquakes: Current predictions indicate a lower risk for strong earthquakes in the near future.
- Monitoring efforts: Ongoing evaluations of seismic and volcanic activities are critical for accurate risk assessments.
- Community safety: By understanding current geological dynamics, authorities can prepare better for potential threats.
Families from Santorini in the Agios Andreas Camp
A total of 104 individuals have relocated from Santorini due to concerns over repeated seismic activity.
These residents have been offered shelter at the Agios Andreas camp, managed by the municipality of Athens in Eastern Attica. Among them, 23 families will receive accommodation, allowing them a temporary respite during uncertain times.
The local authorities are implementing preventive measures to ensure the safety of these newcomers.
These measures may include regular updates on potential seismic risks and guidelines on what to do during an earthquake.
Residents are encouraged to stay informed and take precautions to safeguard their wellbeing.
The community in Agios Andreas is adapting to the influx of new families.
Facilities like schools and communal areas are being optimised to support the incoming residents.
With the presence of students and families, the local atmosphere is becoming more dynamic and communal.
Many of the new residents are facing the challenge of leaving behind their homes, including abandoned buildings and empty properties on the island.
The migration from areas such as Amoudio, Armenis, and Korfou has raised awareness of the ongoing changes to the local demographic landscape.
In this time of upheaval, providing solid support and resources is crucial for both the newcomers and the existing community.
Access to essential services will help foster integration and community spirit.
Current situation today

Stories from Santorini
Living Through the Tremors
A remarkable family on the Greek island of Santorini has chosen to stay despite experiencing over 8,900 earthquakes. The Markakis family resides in Exo Gialos, Fira, maintaining their dedication to their home and numerous animals despite the constant seismic activity.
Sideroula Alefrangi, a Santorini native, lives with her Cretan husband George Markakis and their 6-year-old daughter Apostolia. They share their home with an impressive menagerie: 55 cats, two dogs, two peacocks, two pheasants, and various chickens, goats, and ducks.
When asked about leaving, their answer reveals their priorities:
“We would rather fill a lorry with our animals like a modern Noah’s Ark than pack a car with meaningless belongings.”
Night Watch System:
The family has developed a military-style watch system, taking turns throughout the night to stay alert for tremors. Sleep deprivation has led to peculiar effects, with family members experiencing brief two-minute dreams where reality and imagination blur together.
Daily Challenges:
Their routines have changed dramatically:
- They enter the bathroom wearing protective helmets
- Heating remains off due to explosion fears
- Meal times have become difficult
- Each family member has lost approximately 5 kg from stress
The constant earthquake activity has transformed even the most basic daily activities into anxiety-filled moments. They make the sign of the cross before entering certain rooms, living in constant vigilance.
Their physical exhaustion is evident, yet their sense of duty towards their animals and ancestral land keeps them rooted to their home. Every tremor brings fresh worry, but their determination remains unshaken.
The family maintains their position on the island, watching over their beloved animals whilst adapting to this new normal. Their story exemplifies remarkable resilience in the face of natural adversity, choosing to protect their extended family of animals rather than seek easier circumstances elsewhere.
These daily experiences paint a picture of life amidst seismic uncertainty, where ordinary moments become extraordinary challenges, and where commitment to home and animals outweighs personal comfort and safety.
Memories of 1956
The devastating 1956 earthquake struck Santorini in the early hours of 9 July, measuring 7.5 on the Richter scale. This powerful seismic event claimed 53 lives and left hundreds injured, marking it as the strongest earthquake recorded in 20th-century Europe.
Flora Karamolengkou, now 94 years old, vividly remembers that fateful morning when she was just 25. Living with her family in Mesa Gonia, she recalls the sudden thunderous boom that shook their home at around 5 am. Her memories remain crystal clear even after nearly seven decades.
The immediate aftermath was chaotic. Flora describes the desperate moments as she tried to save her sister’s children:
- A two-year-old sleeping in a cot
- An older child sitting with her father on the sofa
- The collapse of storage space above their bedrooms
- Debris blocking their escape route
The family’s quick thinking proved crucial. Flora’s father managed to:
- Open the dining room door
- Push one child to safety
- Return for Flora and the younger child
- Guide them through the rubble
Recent seismic activity near Santorini has stirred memories of the 1956 disaster. Modern tremors differ from the pattern observed then – today’s sequence shows numerous smaller quakes, creating anxiety about a potentially larger event to follow.
The physical damage in 1956 was extensive:
- Complete destruction of many buildings
- Widespread structural damage across the island
- Collapsed storage facilities
- Blocked roads and pathways
- Severe damage to infrastructure
These events transformed both the landscape and the community’s understanding of seismic risks. The aftermath led to significant changes in building practices and emergency preparedness across the region.
Today’s residents maintain constant vigilance, particularly during periods of increased seismic activity. The memories of 1956 serve as a powerful reminder of the island’s vulnerability to natural disasters and the importance of earthquake preparedness.
