Earthquakes in the Cyclades: Autopsy Lekka in Santorini – “The vibrations are not related to the volcanic site”

The president of OASP and Professor of Natural Disaster Management, Euthymios Lekkas, is in order to perform an autopsy, due to the successive recorded in the Cyclades, near Anafi, Amorgos and Ios. Euthymios Lekkas stressed that the risk of landslides is high in five areas while clarifying that today’s and yesterday’s (01-02.2025) earthquakes have nothing to do with the volcanic area and volcanic chamber neither in the caldera of Santorini, nor in the volcano outside Santorini, Columbus. CORVERSE At the same time he pointed out that the fault that has been giving in the last 50 hours of earthquakes is the fault of Amorgos while leaving open the possibility that “the accumulation of forces could cause an earthquake of 5 – 5,5 not more than 6, though. ” As stated in the lower part of the old port, where the cable car actually ends, during the earthquake that occurred yesterday morning, a rocky mass fell, which has a wedge form. “He was distracted from the pranes and destroyed the roof that existed in the lower space. There are other sticking pieces in the same area, in the same position that we will see in the next few years what actions we will take to reduce the risk here,” he said. The overall picture that exists is that in five areas, Athens, Old Port, Ammoudi, Armeni and Korfus the slippery danger is high, however, as Mr Lekkas added, they have begun to analyse, to see the stability conditions that exist in order to propose the corresponding measures within a short period of time. CORVERSE “In a period of one month the first measures, which are short and immediate, will have been proposed. Then, by summer, the measures that are of a medium-term nature will be proposed, and, of course, the intervention that needs to be made here in order to reduce the risk requires heavy projects, but which must be efficient, economically and in line mainly with the environment,” he stressed. Regarding seismic activity, Mr.Lekkas stressed that this is a seismic activity that is ongoing and which includes the last 50 hours 210 earthquakes. “8 earthquakes are over 4 points on the Richter scale. Most of them occurred this morning. That is why we met at the command of Mr. Kikilia, and with the Committee on Earthquake Risk and the Committee on Volcanic Risk, because the risk exists. Whether the volcanic risk is not involved in current seismic activity. So the two committees met in order to propose the measures that the Civil Protection will apply here in Santorini. Yesterday we decided to close schools in Santorini. Today we decided to close the schools in Amorgos, Anafi and Ios, because the vibrations are particularly noticeable there too. We do it for no other reason except for the earthquake to not find the children in the classroom, ” he stressed and added: “From there, we decided not to meet many people in the spaces, not to have access to the Old Port and Ammoudi and Armeni. In Athens the danger is less so we decided not to take any measures except to have some supervision. And of course, the inhabitants of Santorini should be informed of what they should do from the pages of GGP and OASP in the event of an earthquake. One of them is not to be found or pass through old homes or ruins, not panic and follow the instructions of the authorities. In the event of a strong seismic vibration not approaching the coasts, and of course not crossing paths or roads that have large morphological inclinations so that we do not have any falls during the earthquakes.” At the same time Mr Lekkas pointed out: “As long as the fault is active, it drains. The point is that we don’t know how much energy this breach has, and if the remaining energy will cause some remarkable earthquake in size. We don’t know that at world level. That is, what capacity has been concentrated in a fault.” As explained by this rift that gives the last 50 hours of earthquakes is the breach of Amorgos, – it is two – three parallel faults, from Amorgos to almost outside Santorini – and noted that these faults gave the 1956 earthquake with magnitude 7.6 , which caused widespread disasters in both Santorini and the other islands. “It is certain that this rift will not give an earthquake 7.6 as it gave in 1956 because in order to repeat such an earthquake it must go through millennia. But there is an open possibility that the accumulation of forces will cause an earthquake of 5-5.5, not more than 6, though. Here there were converging views of all scientists and both committees. In these sizes we will have no impact on Santorini, because the epicenters are far away, there is one direction, in any case the effects will be minimal. We are even trying to prevent these few cases in order not to have problems. From the analyses we carried out, we saw that today’s and yesterday’s seismic activity has nothing to do with the volcanic site and volcanic chamber either in the caldera of Santorini, or in the volcano outside Santorini, Columbus”, concluded Mr.Lekkas. Regional Fire Command is on alert. D.) South Aegean It is noted that scenes were placed by the Fire Corps at the facilities of the Santorini Sports Center to stay the units of EMAK and EMOSE , according to the protocol regarding their stay. It is recalled that the Regional Fire Administration (P.S.) has been put on general alert. D.) South Aegean due to increased seismic activity in the marine region of Andros, between Santorini and Amorgos while the regional commander is located on the island as head of firefighting forces. A team of 1st E.M.A.K. with a rescue dog and two teams of 1st E.M.O.D. arrived in Santorini and today a group of drone operators arrived with their equipment, as well as air rescuers.
