We were tied up to a mooring ball at Carlos Rosarion beach moorings on Culebra at 3.30 this afternoon, when we heard a huge explosion and saw smoke rising over Cayo Del Agua.

My wife managed to snap the attached picture.[img]https://www.dropbox.com/s/wutoxdrusvdent1/IMG_0377.JPG?dl=0[/img]

Anyone have any idea what this was?
