Hi Helen. It's similar to Florida. The geologic materials in Florida include carbonate rocks, such as limestone. Over time, water flowing through these rocks can dissolve the rock, resulting in large cavities (in Mexico, these are called "cenotes"). The cavities (also know as karst) can be deep underground, and they can collapse under certain conditions. When they collapse, the ground above can sink!
Would that be the reason for the ' sink-holes' in parts of Florida as well?
Thank you for this Blog.
