“The earthquakes in Santorini come from the rise of lava volcano,” says Professor Geology, Zellidis

Convinced that the barrage of the last few days in volcanic activity, Professor of Geology of Patras University Abraham Zellidis noted on the radio of the First Program. Mr. Zeliidis referred to the earthquakes that have occurred in the last period open to Santorini and explained: “As Africa sinks under Europe in a bow that passes south of Crete, sinking Africa at a depth of about 80 km, it begins melting the material and thus creates a corresponding arc, the volcanic arc that catches Methana, Milos, Nisyros reaches Susaki. So it is known that volcanoes are active. CORVERSE They haven’t given up in a long time. It is only Santorini that operates at regular intervals. The rest have not been active, but we feel that the volcanic arc is active and at any time the rest can be activated. ” In theory, the evolution of a volcano passes through various stages. The stage of calm, the stage of small activity, the intense until we reach the explosion, noted. Also, the duration of each stage is not clear completed. “We record this seismic activity. In other words, when there are no earthquakes, when earthquakes are increasing, etc. For me, I think this seismic activity is linked to the rise of lava from below up. I think this is the reason we have such intense seismic activity. The truth is that watching the seismic sequence seems to be close, either to the finish or to the explosion, ” he noted. CORVERSE Practical ear means Mr. Zelilid said that “slowly rising lava, there are these break-ins, there are earthquakes. But it’s not always like that. There are many times when this activity is released, this pressure from below up and stops. It is released because lava, as it rises, has water vapors, gases, is under pressure and through these breakups they begin to come out into the atmosphere, so it is deflated.” “It also has to do with the chemical composition of lava. Santorini has given different kinds of explosions and calm and explosive. It’s about the magma viscosity. If it’s lighter, if it’s more compact, it can give some flows quiet without figuring out explosions, but you can give explosions. So because we don’t know the chemical composition right now, I think we don’t know how he’ll behave. If he’ll be discharged and how he’ll be discharged. In 2011 a small explosion caused no problems. Probably the magma was a basaltic composition, it was its calm flow and stopped. We don’t know what this will have. (…) You can’t take evidence from an underwater volcano that you don’t see the lava to get and appreciate its chemical composition. All you can do is see the gases coming up and whether it’s detonating or not. That is why they have set up a mechanism for monitoring evolution. But it’s surveillance. So it’s a precaution. Let EMAC go, clear the pools, protect the world. How this situation will develop, no one knows it, ” said Mr. Zellidis. In case there was actually an explosion in Colombo, he noted that this depends on the type of explosion: “Let me just say this. Lately I too read that, for example, Moses ’ Exodus may be associated with an explosion created, a large tsunami. The sea withdrew and then flooded again. That was the Minoan explosion. So a huge tsunami that destroyed a whole civilization. You don’t know how it’s gonna turn out. (…) And I think that’s why meetings and meetings are held every day, watching the seismic phenomenon see how the pressures develop and if the pressures get out. I don’t know if there’s a gas outlet. Apparently some people are recording this. That is, if gases actually come out of Colombo, it means that pressure can be released and this process stopped.” Asked how long such a process could last without detonating explosives, when, for example, in 2011 it lasted for months the microvibration interval, Mr. Zellidis noted that the vibrations were then smaller: “That is why I say that today we are at a next stage. So the lava is almost up. They break rocks, earthquakes are created. So if the earthquakes eventually stop, it means that the phenomenon may have been defused, so the lava isn’t going up yet. That’s why we watch it so carefully to see how it goes. But you can’t interfere. That’s the point.” In question what is the main evidence showing that a volcano may be driven into an explosion, Mr. Zellidis cited the gradual increase in seismic vibrations, the release of gases, the movement of soils, the increase in temperature: “It’s some criteria we’re following. That is, as the magma rises upwards, the more the water of hot springs increases, the water we drink. That’s where we can’t count it. The gas outlet if it increases or not. I don’t know if they count it. The third is seismic vibrations. Of course the seismic vibrations have increased. The fourth remains to be the explosion. The chemical composition, if the explosion is explosive or calm. There are various criteria. Now, the fact that Columbus is underwater creates a subject because you can’t watch it easily. Only with machinery”.
