Why might these watery threats be attributed to this geographical feature?

Answer 1

If you're talking about Scylla and Charybdis, that is because there is a rock opposite the Strait of Messina called the Scylla, a real geographic feature that Odysseus travels through in Homer's Odyssey. As for Charybdis, there is actually a whirlpool, not very strong, that exists in the Strait of Messia (Which again is a real place between northeastern Sicily and Southwesten Italy).

Answer 2

The high likelihood of flooding in this area is due to its low-lying topography, making it susceptible to inundation from heavy rainfall or rising sea levels. Additionally, its proximity to rivers or lakes may contribute to the increased presence of water-related threats. Furthermore, human activities such as improper land use or urban development could exacerbate these risks.
