Thousands of people who live near a volcano in Ecuador in South America are in danger of losing their homes.
The Tungurahua volcano is shooting hot ash 100m into the air after lava began to come out of its top last month.
Children in the nearest school are being taught how to protect themselves as the volcano may violently erupt at any time.
Many families in villages at the bottom of the volcano are not moving as they say they have nowhere else to go.
Victor Rosario, who lives with his family in a village on the lower slopes of the volcano, says he is not frightened.
"This is our land and the volcano will tell us before she acts, and then we will have time to run."
The volcano, which is one of the most active and dangerous in the world, had three eruptions last year.
