Minoan eruption is debated. Early theories proposed that ashfall from Thera on the eastern half of Crete choked off plant life, causing starvation of the local population. However, after more thorough field examinations, the theory has lost credibility, as it has been determined that no more than of ash fell anywhere on Crete. Other theories have been proposed based on archeological evidence found on Crete indicating that a tsunami, likely associated with the eruption, impacted the coastal areas of Crete and may have devastated the Minoan coastal settlements. Another theory is that much of the damage done to Minoan sites resulted from
Cypro-Minoan syllabary decipherment. Currently, the total number of signs on formal Cypro-Minoan inscriptions (approx. 2,500) compares unfavorably with the number known from the undeciphered Linear A documents (over 7,000) and the number available in Linear B when it was deciphered (approx. 30,000). Furthermore, different languages may have been represented by the same Cypro-Minoan subsystem, and without the discovery of bilingual texts or many more texts in each subsystem, decipherment is extremely unlikely. According to Thomas G. Palaima, ""all" past and current schemes of decipherment of Cypro-Minoan are improbable". Silvia Ferrara also believes this to be the case, as she concluded in her
