A man in his 50's is pulled under water (by an unseen shark) and then the water turns red.
A shark jumps off the water making Rory's surfboard smash and sends him flying in the air, Josh tries to pull him onto the jet ski, but is pulled under two times and after the third time he is killed offscreen and the water turns red, we then see his body (missing a leg) float underwater and the shark pulls it away.
While in the staff toilets, Josh hears a gun shot and we see a female worker dead on the floor with a pool of blood beside her head implying bullet in head.
We see the tsunami swipe through the city, and trees and cars are carried in the tsunami and destroying everything in it's path, including the underground supermarket, the tunnel leading to the underground car park and the car park itself.
We see many dead bodies floating in the water after the tsunami hits the supermarket and the car park, including one of the masked robbers (which we later see.)
Heather and Kyle hear something thump their car's rear end, and then we see a dead body float pass.
The tsunami's force a boat's propeller to stab into a woman face, and probably dies offscreen.
Ryan gets a sharp object and cuts a dead body's hand off, and holds it in the water so the shark can go to him while Heather (carrying her dog) and Kyle swim to his upside down van.
Bob comes back from the loading deck, unaware about the group discovering a shark he is pulled the water, appears again and is pulled under again and jumps out of the water and swims to the shelves and Jaime tries to help but dies and floats under the water, and Jaime holds onto his severed hand and throws it back in when she realises.
We see a metal bar jammed into Todd's leg, we see some blood and later Josh pulls it out and blood splatters on the screen.
While trying to reach the vent, Jessup is bitten in half by a shark and is he left hanging for a couple of seconds then Josh and Doyle let go of the rope and his body falls into the water with Kirby after he fell in, the shark then eats his remains and Kirby is pulled to safety.
While Josh is talking to Tina in the flooded supermarket water, a decayed, eaten body suddenly pops up (but they turn around as it comes up.)
Jaime hits the shark with a mallet-like object about three times, then it backs off.
