The Commission decisions After the long -running meeting of scientists, the Professor Papazachosregarding the measures to be followed in the Cyclades islands affected by earthquakes in the marine area between Santorini and Amorgos.

As the professor announced, the committee proposes:

1) Closed schools until Friday in Anafi, Ios, Amorgos and Santorini

2) No gatherings of many people in indoors

3) Not on routes dangerous for landslides and in particular, not in the use of the four Ports of the Caldera

4) Attention to dangerous objects inside the houses

5) The engineers’ controls in buildings have not shown something

6) New meeting of the Scientific Committee to reassess data on Saturday

Mr Papazachos made a statement after the end of the meeting of the two OASP permanent scientific committees, dealing with seismic hazardous and seismic risk reduction, as well as the issues of the Greek volcanic arc, with the main subject being the recent seismic seismic. Extension in the wider area of ​​Santorini.

As he said, this activity occurs in a southwest-northeast direction in the area of ​​Anhydros and in recent days has shown a slight shift to the Amorgos area, which is quite common since it has happened in the past few days to have activity along of the rich zone of Anhydros, but also regressions without it being special. “It is not alarming that residents in different islands feel the earthquakes differently, since both the distance and the way earthquakes occur affects how much every person feels these seismic vibrations,” he said.

He also stressed that beyond this activity, the earthquake stimulation inside the caldera remains at the same level as in the announcement of the Ministry of Civil Protection at the end of January.

“Beyond these phenomena, the committees would like to point out to residents that they should keep with great care the measures announced by the Commission and I am referring to the main ones such as avoiding large rallies, the choice of safe routes against Their move to the islands, in particular the avoidance of areas with a severe landslide risk, especially for Santorini to avoid the use of the four ports of Caldera at which this risk is increased, and all other measures proposed by the Commission such as the reduction of the Dangerous in the houses, not having blocked objects, and so on, “he noted.

He also stressed that as it is known, schools will remain closed on the four islands, namely in Santorini, Anafi, Ios and Amorgos until Friday, while stressing that according to the updates they had by engineers in the committee, all of them Public buildings that have been exposed so far have had very good seismic behavior.

More specifically the Commission’s announcement:

“According to the Commission’s findings, more than 1,100 earthquakes have recently occurred in the Anhydros region from February 1, with a maximum of 3 with a maximum of 5.3 and the earthquake activity continues at about the same levels.

There has been a slight shift in the seismic activity of the Edigers to Amorgos in recent days, but this is common, he said. “It is also not alarming that residents in the different islands feel the earthquakes differently, both the distance and the way earthquakes affect how much every person feels these seismic vibrations,” he added.

The earthquake stimulation inside the Caldera remains at the same level.

In addition to these phenomena, the committees would like to point out to residents that they must keep with great care the measures announced by the Commission, such as the avoidance of large gatherings, the choice of safe routes when moving to the islands, the Avoiding areas with a strong decisive risk. Especially for Santorini, the avoidance of the use of the four ports of the caldera, at which this risk is increased.

In the four islands, namely in Santorini, Anafi, Chios and Amorgos, schools will remain closed until Friday.

The set of public buildings that have been examined so far have exhibited very good seismic behavior.

The Commission will meet on Saturday to re -evaluate the new data and issue the finding. “

On alert scientists – what do they declare

A new cycle of concern is open to yesterday’s powerful powerful earthquakes of 5.3 and 5 Richter in Santorini and Amorgos with scientists today being more cautious about the evolution of the phenomenon.

The announcement is expected on measures from the re -seismic and volcanic risk meeting, and the first data from the seismographs lifted by the area is expected.

See HERE all developments from Tuesday morning

The three potential

As said by Kostas Synolakis, Professor of Natural Disaster: There are three different possibilities:

  1. The rod to finish and to have nothing
  2. The rod to lead to a larger earthquake
  3. The sneaky to lead to a small eruption of the volcano in Nea Kammeni or Columbus, that is, something similar to what we have seen in the last 100 years (the last 100 years have been three small explosions in Santorini in 1925-1926, the 1939-1941 and 1950 and no casualties)

And adds: ‘They said we are doing better, that we are optimistic etc. This is wrong because you cannot say that you are going to go better with Covid -9 with Covid -9“

Has not been the main earthquake

According to seismologists, yesterday’s earthquake, which was the largest so far, does not seem – with the data so far – to be the Lord.

As the Vassilis Karastathis, Director of Geodynamic Institute: “To say an earthquake gentleman must be quite far from the others and not only that, but also accompanied by a characteristic sequence, which has specific characteristics and post -seismic sequence“

And continues: ‘We are in the same situation, in the same form of seismicity. It has stabilized in this form but we always have this reservation, that is, there is a risk of a greater earthquake. “.

Characteristic for the evolution of the phenomenon is that within 2 hours, between 7 and 9 in the morning, 8 earthquakes were held over 4 Richter.

According to the Dimitris Papanikolaou, Emeritus Professor of Tectonic Geology and Geodynamics of the NCSR: “For 2-5 days we see an apparent recession, which is then covered by a larger earthquake, as did the 5.3-earthquake. From the 5.2 Richter earthquake for a few days and some imagined it was time to start shrinking in size and you see that the thing came back.

The question is now: as long as rifts have been activated and earthquakes are giving 5.3 Richter, if the entire accumulation of voltages will be more mature to activate the large 6 -rich rift. “

The phenomenon can take months – suspicions of volcano awakening

Experts point out that the phenomenon can last for months.

In particular, the Professor Kostas Synolakis He stresses: ‘The previous time an earthquakes were magnified from 3 to a maximum of 4-5 Richter in the caldera this had lasts almost a year. The volcano has begun and gives us some symptoms already in August, so it has begun to seem to be a move. If in 2011 we were suspected that the volcano may have been in a wake -up phase, the same is the case and now“

Meanwhile in Santorini, the seismic activity tests the strengths of residents that form the tails in the port to leave.

Santorini for Santorini – Amorgos: Over 14,000 earthquakes – no main earthquake may be ruled out

Over 14,000 earthquakes has detected and identified and identified from the onset of seismic activity in the Santorini-Amorgos zone on January 26 to February 9, 2025, the EKPA (SS) Laboratory of the EKPA, with strict criteria for ensuring the quality of the results. , by mechanical learning methods (artificial intelligence), of which about 12,000 with sizes M≥1.0, according to today’s announcement by the University of Athens.

On February 9, more than 1,100 earthquakes were recorded, with ~ 240 having a size of M≥2.5, 14 earthquakes with M≥4.0, and 2 earthquakes with M≥4.5, with the largest earthquake in size m = 5.0. According to the daily seismic data analysis data (without the use of mechanical learning methods) of the EKPA seismology laboratory, 109 earthquakes have been recorded on 10 February, of which 13 with sizes mq4.0 and 4 with µ≥4.5. The largest earthquake occurred at 20:16:30 UTC and was 5.2, while at 22:37:26 UTC was followed by an earthquake with M = 5.0.

These earthquakes can be considered to be part of the framework of a sequel that will continue with several earthquakes of similar sizes. However, the possibility of a main earthquake may be ruled out. Although largely the seismic activity remains active in a section of ~ 12 km southwest of anhydrous, as in previous days, the focus of the larger earthquakes are found northeast of anhydrous.

Meanwhile today, Tuesday 11/2/25 for the recording of territorial movement in the center of the last days of the seismic activity, from the Geophysical Laboratory of the NCSR, they are held:

  • Installation in the area of ​​Akrotiri Columbus of one (1) new GPS/GNSS Station.
  • Installation at the Anhydrous Anhydrous island of one (1) new permanent GPS/GNSS Geodetic Station (in collaboration with the Geological Department of the University of Patras and the Geodynamic Institute of NSA).
  • Re-counting of the non-monthly Network of 21 GPS Stations in Thira-Therasia-burnt.
