Anyone with a history of lawn use has seen something like this at one time or another. Here at Maison de la Sauterelle we have our own example, providing residents with a miniature Old Faithful event every other day when the automatic timer goes off.
We're now into the fourth week of having this somewhat dubious bubbling perk, despite the fact management & maintenance personnel (seen here walking away, apparently having other things on their minds) being aware of it since the outset. 
Oh well, guess we might as well enjoy it while we we can...
