There have been entire unpopulated islands wiped out by hurricanes off the coast of the US. Louisiana has lost such islands which were large rookeries. So it is possible, but hopefully it is a mistake or exaggeration.

I find it very hard to believe that the second largest island in Haiti could disappear without a trace. The quake that would cause such a thing would have done tremendous damage all through Hispaniola and other islands.
