Solution
The correct answer is "A, B, and C".
a) Mt Saint Helens is a stratovolcano, which is characterized by explosive volcanism. This means that eruptions can be sudden and violent, posing a risk to nearby populations.
b) Rapid melting of the ice cap can lead to violent steam explosions. This is because the heat from the volcano can quickly melt the ice, creating a large amount of steam. When this steam is suddenly released, it can cause a powerful explosion.
c) River channels can direct lahars towards population centers. Lahars are a type of destructive mudflow on the slopes of a volcano. If a lahar is directed towards a populated area, it can cause significant damage and loss of life.
d) It is not a supervolcano. Supervolcanoes are capable of producing eruptions thousands of times larger than normal volcanic eruptions. While Mt Saint Helens is a significant volcano, it is not classified as a supervolcano.
