There is a moment after the volcano eruption that shows a little girl holding a kitten on her front porch who is crying. It is very brief and may be upsetting or disturbing to some viewers, especially children and parents or those who have pets. We never see these two again, which also may be upsetting.
The volcano eruption itself is very intense and scary.
The scene with pyroclastic flow is very intense.
Harry and a woman drive through a darkened, panic-filled street with burning rocks falling from the sky.
As a guy and girl skinny dip in some hot springs, scary music starts and they scream as burning rocks emerge at their feet.
Two bodies are seen floating in some hot springs and their bodies look as if they've been boiled (with welts and many red marks).
A technician gets trapped under a rock slide in the volcano.
The scenes described above in violence/gore may appear frightening to some viewers. A lot of screaming. Children in peril.
