The current situation, the possible emergence of a new volcano, the island of Anafi also in a state of emergency and is Crete endangered by all this?
The island of Santorini, a renowned tourist destination in Greece, is currently experiencing a period of seismic activity.
Although recent tremors have been less intense, potential risks remain.
Experts from the Geodynamic Institute of Athens and other specialists have assessed the situation, noting a decrease in seismic activity, offering cautious optimism.
The tremors range around magnitude 3.5 to 4, with discussions ongoing about the possibility of a larger earthquake impacting the area.
New landslide on Santorini:
Seismologists have speculated about the activation of the Anydros fault, which could lead to a more significant quake.
Despite these concerns, there is no indication of volcanic activity from the Santorini volcano or other nearby volcanic formations.
Residents of the island are gradually returning, hoping for a return to normality.
The situation remains under observation, with experts keenly monitoring seismic data and developments.
However, one of last night’s quakes was not far from us here on Crete, about 58 kilometres north of Neapoli with a magnitude of 3.6 Richter.
Is a New Volcano Emerging in Anidros?

Recent geological activities near Santorini have sparked intense interest in the possibility of volcanic development in the nearby region of Anidros.
A highly respected geology expert has pointed out that seismic activity in Santorini is closely tied to volcanic processes. He suggests that a new volcanic crater might be forming where the epicentres of earthquakes are being detected.
Stages of Volcanic Evolution
Volcanoes tend to evolve through several stages.
Initially, there is a period of quiet. This is followed by early warning signs such as soft rumblings and smaller, sporadic tremors.
Santorini has experienced a surge in earthquake activity over the past ten days, marking an advanced phase typically seen before volcanic changes.
Presently, researchers working in the area have observed significant factors pointing towards increased volcanic activity.
Signs such as rising magma levels contribute to the anticipation of a potential eruption.
Additional indications include increased water temperatures and heightened murkiness in the nearby sea, often seen as precursors to volcanic events.
Monitoring and Predictions
The Greek authorities have taken proactive steps to monitor changes in the region.
The military’s geographic service has been deployed to Santorini to measure geological features, especially focusing on any changes under the island’s surface.
These measures aim to track alterations in the landscape, adding another layer of data to experts’ predictions.
Meanwhile, oceanographic research vessels are also at work.
They are mapping out the sea bed to understand the implications of ongoing geological shifts.
According to Avraam Zelilidis, the epicentres provided by seismologists indicate a new crater might be forming beneath the five-kilometre mark in Anidros. As magma pushes up, it causes walls to crack, triggering these seismic events.
Future Outcomes
The region may face multiple potential scenarios.
The volcanic activity could halt unexpectedly, stabilising the area. On the other hand, magma movement might continue, creating a larger crater.
Earthquakes, linked to the rise of magma and resulting in tremors, could persist as long as the volcanic activity does.
This uncertainty complicates the work of seismologists in determining the behaviour of faults and the specific faults engaged during these processes.
As magma rises, the breaking of rocks leads to erratic earthquake patterns.
Implications for Anidros
If a new volcano is forming, it might not immediately pose a substantial threat to Anidros.
Past experiences with volcanic activity in this part of the world offer some reassurance.
Local researchers and experts continue to work closely to understand the developing situation and provide accurate forecasts.
Anafi Under Emergency Conditions
The Greek island of Anafi has been placed under a state of emergency following significant seismic activity in the area.
The decision was made by the General Secretary for Civil Protection, with the intent to handle urgent needs and manage the impact of recent earthquakes that have affected the region.
This emergency status will remain in effect until 13 March 2025.
The declaration reflects the ongoing challenges faced by the island and its nearby neighbours, dealing with frequent and intense tremors.
Seismic activity has been a notable concern between the islands of Santorini and Amorgos, requiring Anafi’s inclusion under emergency protocols.
This is part of a wider effort to secure safety and provide necessary support to residents and visitors.
The declaration aims to mobilise resources and coordinate actions to safeguard communities and infrastructure from potential damage.
Key Points on Anafi’s Emergency Status

Anafi’s current condition, set within the broader regional context of the Cyclades, marks an essential phase in the community’s preparedness and response journey.
The ongoing efforts serve as a reminder of the ever-present need for vigilance in areas prone to seismic risks.
Crete is Not Endangered by the Earthquakes on Santorini
Earthquake expert Lekkas for talks in Heraklion
In recent weeks, the Greek islands, particularly Santorini, have experienced an unusual increase in seismic activity, raising concerns among residents and authorities.
This has led to questions about potential risks to nearby areas, including Crete. However, experts assure that Crete remains unaffected by these tremors.
Seismic Patterns and Predictions
The earthquakes on Santorini are part of what is described as an “earthquake swarm,” comprising thousands of smaller tremors.
Although significant in number, these quakes mostly register below 5.3 on the Richter scale. The phenomenon is characterised by its high frequency and relatively low intensity.
Experts are closely monitoring the situation, projecting that the seismic activity will likely continue, albeit with minor ramifications.
Despite the intensity of these activities, an earthquake of considerable magnitude is not anticipated.
The planning on Santorini incorporates assessments that initially considered potential quakes up to 6.0 on the Richter scale, yet recent evaluations indicate this scenario is increasingly improbable.
Meanwhile, //geological separations// ensure that Crete remains stable and out of harm’s way.
Differences in Geological Features
A critical factor ensuring the safety of Crete lies in the distinct geological differences between the islands of Crete and Santorini.
These differences significantly mitigate the impacts of seismic events on Crete, even if Santorini experiences heightened activity.
As explained, the geological formations that underpin each island do not transmit seismic energy between them effectively, thus safeguarding Crete from the quake disturbances originating on Santorini.
Expert Assurance on Safety
Leading experts, including Evthymios Lekkas, a Disaster Management professor, have publicly affirmed that Crete faces no danger from Santorini‘s seismic activity.
They stress the absence of any connections between the current seismic occurrences on Santorini and the kind of volcanic activity that could jeopardise Crete.
Notably, these are considered separate phenomena, ensuring Crete’s safety.
Impacts on Infrastructure and Preparedness
Regarding Santorini’s infrastructure, public buildings have largely withstood the seismic activity without significant issues.
Areas at risk are primarily localised and involve structures that do not meet required standards, such as buildings in the Caldera region.
Meanwhile, Crete’s infrastructure and its seismic preparedness have benefitted from previous exercises and plans designed for natural disaster management.
Community and Government Response
In Crete, scientific collaboration with regional authorities has been ongoing to improve local education and preparedness related to natural disasters.
Efforts include training a substantial portion of the population in disaster management, ensuring readiness for any unexpected events.
This collaboration is continuous, focusing on advancing the region’s capacity to handle such circumstances proficiently.
