In 365 AD, a massive undersea earthquake near Crete triggered a catastrophic tsunami that devastated coastal cities across the Eastern Mediterranean, including Alexandria. This natural disaster caused widespread destruction and loss of life, highlighting the vulnerability of ancient civilizations to geological events.
