WATCH: Death toll from Dorian climbs to 30 in Bahamas
When Hurricane Dorian struck the Bahamas as a Category 5 storm, it wrecked havoc on the idyllic islands. Satellite images taken in 2018 and on Thursday show in great detail Dorian's destructive force on Great Abaco Island, where some of the worst damage occurred.
Hurricane force winds ripped apart buildings and tossed ships ashore. Whole towns and the local airport became submerged, complicating rescue and relief efforts.
"I have never seen destruction like this on this scale on an island before," ABC News correspondent Marcus Moore told "Good Morning America" Tuesday from Marsh Harbour, a town in the Abaco Islands.

The death toll in the Bahamas reached 30 on Thursday, but Health Minister Dr. Duane Sands told a local radio station that the final death count will be "staggering."
