Thera was just a small part of the Minoan civilization centered on the island of Crete. The explosion of Thera was once thought to have causes serious damage to the Minoans in 1450 BCE, but this catastrophe was redated to before 1628 BCE using ice cores. Also it is now thought that the ash cloud mostly missed Crete itself. The lack of gold found in ruins on the remains of Thera indicate that the island was evacuated before the final explosion.
That leaves mainly the tsunami. The Minoans had a large merchant fleet, but it evidently survived: ships at sea are not endangered by tsunami. In any event the Minoans recovered quickly. Their civilization continued for about 200 years before attacks from the Greek mainland destroyed some of their cities.
There just does not seem to be much similarity with Plato's account. Thera or Crete do not resemble Atlantis. And the greater Minoan civilization went on almost as if nothing happened after the eruption. The timing and location are all wrong to be Atlantis. Plato puts it in the Atlantic and thousands of years before the Minoans.
The civilization of Atlantis lasted over 50000 years. They had settlements in the Mediterranean, Africa and America. They mined gold, silver, tin, copper and inconel(orichalcum) in America and even constructed roads in South America to get the metals out. They are said to have mined uranium in Africa and constructed nukes. They had wireless transmission of power which they extracted from sun light or the solar wind. Their aircraft and ships used this wireless power and carried no fuel. They could levitate large stone blocks and other objects. They had a Ray that could reduce anything to fine powder. That is how the got rid of their trash, but it is also a weapon.
Atlantis had high technology but it did not resemble ours. Tesla may have reinvented some of it, (He said he could pulverize the Empire State Building in seconds. And his wireless power.) but most of his work has been classified and weaponized. The Coral Castle is said to be an example of construction using levitation so that may be possible today: "if you know how to do it, it is easy".
