Thera is the largest island of Santorini, a collapsed caldera about 100 km distant from Crete.
The Thera eruption has been identified by ash fallout in eastern Crete, and in cores from the Aegean and Eastern Mediterranean seafloors.
The cataclysmic eruption of Thera led to the volcano's collapse into a submarine caldera, causing tsunamis which may have damaged naval installations and settlements near the coasts. The level of impact of the Thera eruption on the Minoan civilization is debated.
Claims were made that the ash falling on the eastern half of Crete may have choked off plant life, causing starvation.
It was alleged that 7-11 cm of ash fell on Kato Zakro, while 0.5 cm fell on Knossos. However, when field examinations were carried out, this theory was dropped, as no more than 5 mm had fallen anywhere in Crete.
Earlier historians and archaeologists appear to have been deceived by the depth of pumice found on the sea floor. It has now been established that the pumice oozed from a lateral crack in the volcano below sea level.
A huge earthquake in around 1700 BC destroyed many palaces including Knossos, though these were all rebuilt by the Minoans. In fact these palaces were not only rebuilt but also became complex multi storey living quarters with facilities such as drainage. They were also beautifully decorated with Minoan fredcoes.
·During this late period there is evidence in tablets inscribed in Linear B language that the Mycenaeans (emerging power from mainland Greece) controlled the entire island, while many Minoan sites were abandoned for a long time. ·We cannot be certain of the causes for this sudden interruption of the Minoan civilization. However scholars have pointed to invasion of outside forces, or to the colossal eruption of the Thera volcano as likely causes. ·Professor Marinatos was the first to suggest in 1939 that the eruption of Thera, along with the associated effects, was the cause for the catastrophe. ·The theory argues that the earthquakes destroyed the palaces, tsunamis obliterated the fleet and peers of the Minoans, and the volcanic ash of Thera covered the whole island destroying crops and suffocating animals. ·Another factor that might have contributed to the end of Minoan civilization is the invasion and occupation of Crete by the Mycenaeans.

There is evidence that the trade networks collapsed, and that Minoan cities perished by famine. The Minoans' grain supply is believed to have come from farms on the shore of the Black Sea.
Many scholars believe that ancient trading empires were in constant danger from uneconomic trade, that is, food and staple goods were improperly valued relative to luxury goods, because accounting was undeveloped.
The result could be famine and decline in population.
One theory of Minoan collapse is that increasing use of iron tools impoverished the Minoan traders.
When the trade networks ceased, regional famines could no longer be mitigated by trade.
Another theory is that Minoan naval capabilities were damaged in some fashion by the explosion of Thera.
This may have led to a conquest by the Myceneans. The Myceneans probably lacked the skills to manage a large trading empire.
The impact of the Thera eruption on the Minoan civilization is still controversial. Since the Thera eruption is thought to have been one of the most powerful in the past 10,000 years, archaeologists and geologists have been arguing over why there is such a big gap between the radiocarbon date of the eruption (1628 BC by bristlecone pines and 1645 BC by the Greenland ice sheets) and the date of the fall of the Minoans (c. 1450 BC).
This gap has sparked the interest of experts all over the world and there are now increasing amounts of evidence and theories as to why and how the Minoan civilization of Crete collapsed.
These theories all revolve around the Theran eruption, estimated now to have reached a reading of VEI-7, which would have devastated the island of Crete only 70 miles (100km) or so away.
An eruption of this magnitude is thought to have pushed tsunamis towards the island, destroying its ports and fleets. Being a trade centre Crete relied on its seafaring capabilities for the stability of its economy.
The next major theory is that the volcanic ash blocking out the Sun would have resulted in a famine for a number of years.
Some experts believe that in these moments of vulnerability the Mycaneans took advantage and conquered the island.
Two events lead to the end of the Minoan civilization.
First event that weakened the Minoan Civilization was the volcanic eruption on the Aegean island of Thera (end of the 15th century B.C.) (Hammond, 2009).
The eruption generated a devastating tsunami on the north coast of Crete, as well as a fallout of ash (Chadwick, 2009).
Chadwick (2009) hypothesised that the natural disaster weakened the Minoan kingdom where they were unable to resist the invasion by the Mycenaean civilization
The final decline occurred about 12th century B.C (Hammond, 2009).
The second event was the rise of the Mycenaean civilization upon Crete, where they seized the capitol (Hammond, 2009).
Leadership for the Minoan civilization was based on bureaucratic monarchies (Hooker, 2009).
Beneath the monarchy was a large administration of bureaucrats (Hooker, 2009).
A great area of interest was trade and mercantilism with neighbouring countries (e.g. Egypt) (Hooker, 2009).
Crete was associated with “thalossocracy” or sea power (Hooker, 2009).
Crete built warships to trade and to protect themselves from pirates (Hooker, 2009).
The palace of Knossos was only destroyed twice in its history, once from fire (roughly in 1700 BC) and a wall collapse, the second and later destruction from a major earthquake which ravaged Crete.
The later earthquake not only brought destruction to Knossos, but to both Kato Sakro and Mallia as well. These events, however, were not to end Minoan civilization.
Not until 1450 BC was the end of Minoan Civilization realized. The final collapse of the Minoan state remains a half-solved mystery.
Two factors are thought to have contributed to the end of the Minoan: the possible eruption of the volcano Thera and the rise of the Mycenaean civilization upon Crete.
All archaeological evidence suggests that the Cretan states of the first half of the second millenium BC were bureaucratic monarchies.
While the government was dominated by priests and while the monarch seemed to have some religious functions, the principle role of the monarch seemed to be that of "chief entrepreneur," or better yet, CEO of the Cretan state.
For the Cretans operated their state as a business, and entrepreneurship seemed to be the order of the day. While the bulk of the population enjoyed the wealth of international trading, the circumstances of that trade was tightly controlled from the palace.
Beneath the king was a large administration of scribes and bureaucrats who carefully regulated production and distribution both within the state and without.
This administration kept incredibly detailed records, which implies that they exercised a great deal of control over the economy.
In order to facilitate trade, the Cretans and their Aegean relatives developed the most advanced navy that had ever been seen.
While scholars earlier believed that Crete must have been a "thalossocracy," that is, a "sea power," that view has been seriously challenged.
The Cretans probably did not develop a military navy, as did the Egyptians, but concentrated solely on trade and mercantilism.
They did build what looks like warships, but it seems that these warships were most likely mercantile ships with the capability of defense against pirates.
