Sixty – two years ago, the spirit of the inhabitants of Amorgos and neighboring islands came from the 4.7 degree earthquake on the Richter scale, which occurred at dawn Wednesday in the submarine area 29 kilometers southwest of Amorgos and 30 kilometers deep. in Athens. The losses were not caused, but memories of the 7.5-degree earthquake and the death of 53 people are still alive.
According to the experts, what is worrying about them is the region where the earthquake took place and not its size. As explained, the research director of the Geodynamic Institute of Athens, Vasilis Karastathis, is a well-known rational area stretching from Santorini to Amorgos – and a little further.
In this region, 62 years ago (July 9, 1956), a 7.5-degree earthquake killed 53 people in the surrounding islands. Before the major earthquake of July 8, there was a tilt of 4.9 degrees.
Then, the main earthquake followed a strong drift of magnitude 6.9. A large tsunami caused a tsunami that, according to Vasilis Karastathis, would have reached 25 meters on the coast of Amorgos and 20 meters on the coast of Astypalea. The earthquake combined with the tsunami damaged 529 homes in Santorini, Amorgos, Anafi and Astypalea.
It should be noted that on April 10, 2018, an earthquake of magnitude 4.8 on the Richter scale had occurred in the same area and before the earthquake on Wednesday, there were preliminary tensions: 3.6 and 3.1 points on November 26 and 4.7 points on November 27. Wednesday's earthquake followed aftershocks: at noon, there were four sizes of 3.8, 4, 3.4 and 3 degrees.
For his part, Thanasis Ganas, a geologist and research director at the National Observatory of the Athenaeum, described the current seismic activity as "usual for the region". As the earthquake indicates three kilometers east of the island of Anhidros, where there is a known tectonic moat. The OASP President, Professor Efthimios Lekkas, also appealed.
