Realistic-
1.They had the events (earthquake, lava, lahar, mudflow, pyroclastic flow) in order.
2. Harry tested the water in the lake and that is one way of finding out if an eruption will happen.
3. The lake would become acid because of the eruption.
Unrealistic-
1. The earthquakes before the eruption would not have caused all of the buildings and bridges to fall.
2. They would not have been able to scream or inhale in all of the ash there was.
3. The lava would have completely destroyed the grandma's house and they would have been killed.
4. All of the events that they some how managed to escape from (Lava,Ash, driving through ash, dodging every falling building, not getting shocked by lightning, getting across an acid lake, crashing through a mine, dodging bombs and blocks, and surviving a mine that collapsed on them) would have never happened.
