New earthquakes in the Aegean and extension of the state of emergency for Santorini.
New strong earthquake of magnitude 5 Richter at dawn between Santorini and Amorgos
A powerful seismic event measuring 5 on the Richter scale occurred at 03:14 on Wednesday between Santorini and Amorgos.
According to data from the Geodynamic Institute of Athens, the earthquake’s epicentre was located in the sea, approximately 24 kilometres south-southwest of Arkessini on Amorgos.
The tremor was notably felt in both Santorini and Amorgos, as well as in the wider Attica region.
Shortly after the initial quake, a second tremor of magnitude 4.6 struck, 25 kilometres southwest of Amorgos, with a focal depth of 14.2 kilometres.
This sequence of events was accompanied by additional shocks measuring 4.2 and 4 from the same epicentre, following closely thereafter.
There had already been numerous earthquakes exceeding 3 on the Richter scale prior to this significant activity.
Such geological phenomena highlight the ongoing seismic risk in this region, as noted by experts like Efthymios Lekkas and the relevant authorities.
Extension of Emergency Protective Measures
Seismic “Marathon”
The recent string of seismic activity, often termed a “marathon” of earthquakes, involves a series of small to moderate tremors occurring consecutively.
This phenomenon is unusual and presents challenges for scientists attempting to understand its dynamics.
Experts have noted that the sequence includes various vibrations, and currently, there is no consensus on identifying a main shock.
Typically, a primary quake is recognised when it exceeds the previous shocks by at least half a magnitude on the Richter scale, but here, that distinction remains uncertain.
One of the primary concerns related to this seismic sequence is the potential for further expansion of the epicentres across a larger fault area.
Should this occur, it may signal that the geological structure is more extensive than initially assessed.
This observation is crucial, as it informs not only scientific understanding but also public safety measures.
The emphasis is on closely monitoring the situation and gathering data to ensure community safety, as vibrations may pose risks in affected areas.
In anticipation of potential threats, the National Tsunami Warning Centre has positioned a tide gauge along the northeastern coast of Santorini to monitor sea-level changes.
This precautionary measure is part of broader efforts to enhance detection systems.
Continuous addition of seismic sensors aims to provide comprehensive data collection necessary for in-depth analysis of the ongoing seismic sequence.
The extraction of data from two previously submerged seismographs retrieved from the Caldera will yield significant insights into the precise epicentre of each quake.
Such information is invaluable for scientists, allowing for more accurate predictions regarding the trajectory of this seismic series.
By improving understanding and communication, authorities can better prepare and respond to the needs of residents in areas experiencing these tremors.

The Seismic Activity Became Noticeable Last June
Earthquake activity near Samtorin June 2024 to 25 January 2025
In June 2024, the Santorini region began to experience significant seismic activity. Small clusters of tremors were noted by the local seismology laboratory, indicating the potential for a larger seismic event.
This activity initially started as minor quakes within the Santorini Caldera. By July and August, the tremors became more frequent, suggesting the possibility of an impending larger quake.
By mid-September, the seismic situation in Santorini intensified. This level of activity within the caldera had not been seen since the period of 2011 to 2012.
It was during this earlier period that Santorini also experienced a burst of seismic action.
To ensure accurate monitoring, the seismology team set up permanent seismic stations across Santorini back in 2011. These installations have since been pivotal in tracking the progression of seismic events.
Unlike the caldera, the underwater Kolumbo volcano, located about 8 kilometres northeast of Santorini, has been regularly active over time.
During the 2024 sequence of events, the epicentres of these quakes in Santorini were mainly located in areas such as Nea Kameni and the broader region of Imerovigli to Fira.
They followed a line from northeast to southwest, referred to as the “Kameni Line”. Meanwhile, seismic activity also emerged east of the Kolumbo volcano, similar to the pattern observed in 2011-2012.
Between June 2024 and January 25, 2025, over 1,600 earthquakes were recorded in the Santorini-Kolumbo area. The largest was registered on January 25, with a magnitude of 3.8, centred on the southeastern coast of Thirasia.
On January 26, a new set of quakes began to surface east of Kolumbo, escalating noticeably the following day.
By January 29, more than 1,300 tremors had been detected in this region.
The use of artificial intelligence played a key role in identifying these quakes, with strict criteria ensuring the accuracy of results.
As the events unfolded, they painted a complex picture of seismic behaviours, requiring continuous observation.
By the end of January, over 2,500 earthquakes had been detected, with more than 800 on February 1 alone.
The dynamic nature of these events highlighted the evolving geological landscape around Santorini.
These developments hint at an ongoing seismic process, with a network of professionals working tirelessly to provide updates and maintain public safety.
Understanding the pattern and implications of these activities is crucial for anticipating future seismic reactions in the region.
