We were on the ship and exited yesterday. We did not leave the ship that day so we were on board when this occurred When the signal went off we clearly heard that it included a first aid response. We knew that someone had to be injured, but also knew that no passenger response was required. It must have been a low pressure release ( speculation on my part) because I did not find anyone who heard an actual explosion Afterwards tne captain explained that there were several water leaks across the ship because of the rapid temperature changes in the lines ( thermal shock and also maybe corresponding pressure changes). We were told the water leakage damaged electrical equipment in the Hard Rock Lounge and that caused the show to be canceled
This was such a sad end to a wonderful cruise
