A diver can be seen in the cylindrical AquaDom aquarium.

The AquaDom, the world's largest cylindrical aquarium, burst on Friday morning in Berlin, releasing more than 264,000 gallons of water onto the premises. There was "unbelievable maritime damage" according to the police.

Dead fish, bent support beams, and broken glass can be seen in videos and photos posted to social media by hotel guests. There were no human casualties and two people were injured by glass shards.

It is not known what caused the incident. According to Euronews, local authorities are looking into it. A member of the German Parliament, who is staying at the Radisson Collection Hotel, told local outlets that she thought there was an earthquake this morning and that the AquaDom burst. She said it reminded her of a war zone.

According to the New York Times, Weeser told a local TV station that it was a picture of destruction. Those that might have been saved were dead.

There were 100 emergency responders dispatched to the AquaDom. The police evacuated the guests from the hotel out of concern for the structural integrity of the building. The AquaDom was temporarily closed because of the destruction.

The fate of most of the aquarium's inhabitants is difficult to see in the videos. Police and firefighters at the scene didn't give much information about what happened to the fish

Berlin officials believe that the fish in the AquaDom cylindrical tank are not likely to survive. The fish in other smaller aquariums in the building were at risk because the AquaDom had shut off the power.
