We've written about reporting sinkholes--hopefully before they get bad--on SeeClickFix. While this is not new to the site, it's an important reminder that being engaged doesn't mean just reporting graffiti and parking meters. 

We know a lot of times these events happen with no noticeable warning, but in many cases holes, dips, and fissures can be documented before anything really bad occurs--and many cities want to receive them!

The sudden formation of a sinkhole in Florida today fortunately ended without human damage, but it's a healthy reminder that up to 20% of the United States alone are areas susceptible to sinkhole damage.

This heatmap shows areas of the continental U.S. potentially affected.
