Factual error: In the scene during the evacuation of the Cedar Hospital, Dr Calder is assessing a patient and uses the defibrillator on him. She puts the paddles in the wrong spots on the chest - right hand one over the abdomen and the other over the left lower chest. As a doctor she should know to put the right hand paddle over the upper right chest. This is important for the normal electrical pathway through the heart to reset and restart normal cardiac activity. (01:27:22)
Continuity mistake: After the bus is flipped on its side and Roarke and Barnes stop to rescue a man lying in ash, a tree falls blocking their escape with high flames, forcing a ladder truck to save the trio. When the ladder is unable to be lifted because of the weight and extreme heat, the fireman explains he will have to swing them out instead. The ladder swings in the direction of the flaming, downed tree, but the flames from the tree no longer seem to be a hindrance.
Character mistake: When they're literally watching lava creep down the street Roark says "whatever this stuff is" (something like that). 2 things: 1) how does he not realise it's lava, and 2) although it's weird to have lava in LA, Amy already told him that lava could push through from the tar pits, so he should have been able to figure it out.
Suggested correction: Even if he knows what it is, he is still in denial and just doesn't want to say the name of it, as it's uncomfortable to say.
