On June 2nd, I posted something saying I guessed the 2 holes
( piping features ) in Guatemala
were 1800 meters apart.
Someone has published a map with a scale.

According to that map, it is more like 1300 meters.
The city supposedly has storm sewer drainage tunnels about
3 meters in diameter, and are supposedly old and in disrepair.
There does not seem to be any real news about this hole, or what
they did about the old hole 3 years ago.
For example, there is hardly a mention of it on the web-site:
http://www.earthmagazine.org/
Here is an illustration showing how the holes formed:
