2025 earthquakes

Santorini experienced an earthquake swarm in early February 2025.[46][47] Hundreds of tremors occurred in the Aegean Sea in the vicinity of the island, some measuring up to magnitude 5. They are expected to last for weeks. As a precaution, much of the population of Santorini was evacuated by sea and by air.[48]

During the weekend of 1 and 2 February, more than 200 undersea tremors were detected. The epicenters were primarily in a growing cluster between the islands of Santorini, Anafi, Amorgos, Ios and the uninhabited islet of Anydros. Many of the earthquakes registered magnitudes above 4.5 on the Moment magnitude scale. The strongest earthquake of the swarm occurred on 4 February, and measured Mw 5.3.[49] While experts determined the earthquakes were tectonic rather than volcanic in nature, the pattern and frequency of seismic activity prompted significant concern among scientists and authorities.[50] Seismologist Manolis Skordylis indicated on public radio that a seismic fault line had been activated with potential to cause an earthquake exceeding magnitude 6.0. Scientists emphasized that the main seismic event might not yet have occurred.[51]

Greek authorities implemented several emergency measures, which included the deployment of emergency crews and a 26-member rescue team with a rescue dog to the region.[50] Schools were closed on Santorini, Anafi, Amorgos, and Ios.[52] Access to areas near cliffs was restricted due to increased risk of landslides. In Fira, several gathering points for evacuation were established.[50][53] Access to shorelines and certain ports, including Santorini's old port, was restricted due to tsunami risk, with residents instructed to move inland.[51]

Greece's Minister of Civil Protection Vasilis Kikilias emphasized the precautionary nature of the response. Prime Minister of Greece Kyriakos Mitsotakis, who spoke while in Brussels, called for calm while acknowledging the intensity of the earthquake swarm. Hotels were told to drain their swimming pools to minimize potential earthquake damage to structures.[50] Aegean Airlines doubled its flight frequency between Athens and Santorini for a two-day period to carry out evacuations. Ferry companies increased their service frequency in response to surging demand, resulting in long queues forming at evacuation ports.[51] Around 6,000 residents left the island by ferry beginning on 2 February, while up to 2,700 left by air from 3 to 4 February. The South Aegean Regional Fire Department was placed on general alert.[54] A state of emergency was declared in Santorini by the Greek government on 6 February.[55]

In Turkey, the Disaster and Emergency Management Presidency (AFAD) and the Mineral Research and Exploration General Directorate (MTA) warned that the earthquakes could lead to volcanic activity around the Kolumbo submarine volcano off Santorini.[56]

https://en.wikipedia.org/wiki/Santorini#2025_earthquakes

"From 26 January to 8 February 2025, the Seismology Laboratory (SL) of the University of Athens registered more than 12,800 earthquakes in the Santorini-Amorgos zone."

Earthquake details
A major seismic crisis has been affecting the Santorini-Amorgos region since 27 January. To date, more than two thousand earthquakes with magnitudes up to 5.3 have been recorded and 9 earthquakes have a magnitudes greater or equal to 5.0. These earthquakes are concentrated about 25 kilometers northeast of Santorini and 25 kilometers southwest of Amorgos islands. Following a slight decrease in seismicity between February 4th and February 9th , there has been an apparent resurgence in seismic activity since February 10th as shown in the figure 4.

More than 10,000 residents and tourists have been evacuated from the island of Santorini.

We understand that this is not an easy situation for the people of the region, so please listen to the Greek authorities and be aware that, as usual, many people are making nosense statements on social media. Stay safe.

If you felt these earthquakes, please share your experience with us. Your testimony will be useful to update the Intensity map here below, where the felt intensities represent the effects of the earthquake over the impacted area

Pre-earthquake signals were just recently observed and conditions are lining up that strongly suggest that a high magnitude earthquake may be about to occur in the location of the ongoing massive seimsic swarm in the Aegean Sea off the coast of Santorini Volcano.

And here are the earthquake electromagnetic signals that were observed two years ago 4 days before and during the M7.8 and M7.5 Turkey-Syria earthquakes (Fe. 6 2023)

Geophysicist Stefan Burns investigates the massive earthquake swarm occurring right now off the northeast coast of Santorini Volcano in the Christiana-Santorini-Kolumbo Volcanic Field, this time investigating the M7.8 earthquake that occurred just nearby in 1956, and an surprisingly similar earthquake swarm that occurred a few years ago in the Aegean Sea but with some striking differences... Are we witnessing the birth of a new submarine volcano?!

Pre-earthquake signals have been observed nearby in Italy on February 9th and 10th closely correlated with significant M5+ earthquakes from the Santorini Seismic Swarm, and new evidence suggests volcanic processes may be the cause of these unusual extremely-low-frequency signals.

Highly anomalous electromagnetic signals have now been observed in Italy 4x in four days, indicating that something very strange is happening in the Mediterranean region, most likely located in the Aegean Sea at the seismic swarm near Santorini Volcano. Complete Geophysics Report by Stefan Burns
