Seismologists are constantly watching the intense seismic activity that continues between Santorini and Amorgos.

At 11:30 another earthquake of 3.9 Richter marked 17 km southwest of Amorgos with a focal depth of 13.9 km.

The suspension in the X of the Euro -Mediterranean Seismological Center, which speaks of a change in the earthquake pattern, which could also mean a possible arousal of the volcano and an inexplicable “noise” has caused even greater concern, with seismologists, however What is going on.

Some scientists like to draw conclusions that do not understand how much damage they can do in a place being tested, “Professor Dimitris told SKAI on Saturday morning. Papanikolaou, Commenting on the posting of the Euro -Mediterranean Seismic Center.

Mr Papanikolaou pointed out that it is common to hear noises in earthquakes.

“Small earthquakes are superficial if they break, when the rock breaks and gives the earthquake, the friction that makes the break is spreading especially through the sea and reaches this hum everywhere,” he said.

He expressed the hope that this quietness that has prevailed in recent days “let’s hope that it would really be some decline”.

“We have to be very careful, cautious. We will be patient for a few days to see how things are evolving, ”he said.

In addition, he stressed that the real risk in the event of an earthquake of 6 Richter is for Santorini. “Anafi, Ios and Amorgos are not in danger of all 6 Richter,” he said.

Karastathis: Tectonic activity in activated fractures is associated with a magma rise

“The recession is continuing, but it must be consolidated to be confident that the sequence is on the ground,” the Director of the Geodynamic Institute told ERTnews today, saying that the seismic activity in the area was mild at night. In terms of wicked activity in Santorini o Vassilis Karastathis He stated that “tectonic activity in the activated fractures is linked to a magma rise and the entry of fluids into the tectonic structures, which maintains the seismic sequence. At the same time, it has triggered other geodynamic processes, which are evaluated. “

As the scientist told reporters, “we are not only evaluating seismic activity but also soil deformities, as well as all the data we collect. We need to be very careful in our announcements and cross the information before we make it public. “

Regarding reports from international seismological centers for microscopes attributed to a magical activity under Santorini, Mr Karastathis clarified: “It is a very dense sequence of micro -columns that caused the feeling of a constant vibration, which is characteristic of volcanoes. However, if we look at the signals, we will see that these are extremely small events, successive minorisms that gave this impression. This activity was located in the area of ​​Anhydros, far from the Santorini volcano. “

The director of the Geodynamic Institute noted that “the nature of this seismic sequence is such that it forces us to maintain reservations. There are always fluctuations, but in recent days there has been a recession compared to the early days of the phenomenon. If this trend continues, we can be optimistic. ” However, he noted that “seismic activity is not examined individually. It is important to evaluate other factors, such as soil deformities. “

Regarding the potential magazine, he said that “it seems that tectonic activity in the activated fractures is linked to magma rise and the entry of fluids into the tectonic structures, which maintains the seismic sequence. At the same time, it has triggered other geodynamic processes, which are evaluated. “

Synolakis: Pure Volcanic Earthquakes

Pure volcanic was described yesterday’s earthquakes in the Santorini -Amorgos zone by Natural Disaster Professor Costas Synolakis, who called for a wider meeting with foreign experts.

“Last night there were an earthquakes of a different type, indicating that there was a volcanic magma. Although the vibrations stopped in one and a half hours, it was clear that it was pure volcanic earthquakes, “Mr Synolakis told ERT.

According to the professor, “a volcanic flock happened which, as seismologists say, had too much noise.” He said now, scientists are considering other parameters. “It’s time to become a wider meeting with foreign experts who have experiences.” And as he said, “we cannot only rely on the 2011 experience. We have to compare the phenomenon to dozens of other cases to understand where we are being driven.”

At the same time, Mr. Synolakis said that there was a decrease in seismic activity, which shows improvement in the situation. “We can’t say that we are doing better only by the number of earthquakes. If their nature changes so quickly and become clear volcanic, then the phenomenon must be reviewed, “he said.

Asked how he estimates that the phenomenon will evolve, he said there are two possible versions: “The rise of the magma can cause the formation of a small volcanic cone or lead to a larger earthquake.”

Law: Let’s put aside “Great Disaster” scenarios

Let’s put aside “major disasters” scenarios that only lead to panic and uncertainty, “the volcanologist, Evi Nomikou, demanded on her facebook post on Facebook.

In her post, the Professor of Geology of the NCSR notes that the likelihood of activation and the Anhydros rift remains, with a potential earthquake size of 5.8-6.1 Richter. He also explained that the lifting of the magma is tectonic tendencies in the supernatant thin bark, resulting in the activation of normal gravity cracks, which allow the rise of fluid material by opening space and the creation of volcanic veins.

The post of Mrs Law:

“How can you explain a complex geological phenomenon that evolves into an active marine space where volcanoes interact with tectonics? With a form … the knowledge of many years of research and the collaboration of foreign and Greek associates!

So, based on the time evolution of seismicity from late January to the present day and geophysical data from the underwater space, both in the upper bark and deeper than the analysis of the miracle bodies, there is a most likely cause of seismic stimulation with earthquakes size 4- 5 The magma penetration under the echo of anhydrous up to 4 km depth.

The lifting of the magma has tectonic tendencies in the supernatant thin bark, resulting in the activation of regular gravity cracks, which allow the rise of fluid material by opening space and the creation of volcanic veins. The likelihood of activation and the rift of anhydrous remains with a possible earthquake size 5.8-6.1. The phenomenon is expected to take (possibly weeks) as long as the wicked chamber continues with new material from the lithospheric cloak in the background. The possibility of monitoring the area with a combination of research methods will allow safe assessment of the whole evolution of the unprecedented geodynamic process !! And this is what the whole scientific community does!

The fluid movement we explain these days was recorded in seismographers a few hours ago! The focuses now … are found again in anhydrous !! Let’s not forget that similar processes with cash movements had recorded in 2011-12 without a volcanic explosion !!!!! And as veins we always admire them on the NE side of the cobblestone next to the sevenaps.

Volcanoes are the breath of our planet and the movement of the caterpillar in the earth’s out Ordinary process! So we watch them and put aside “great disasters” scenarios that only lead to panic and uncertainty. ”
