Which risk escalates when shield volcano slope instability occurs?

💡 Explanation

A slope collapse creates instability and can cause a debris avalanche because gravity pulls down material rapidly. This process increases the flow velocity of volcanic debris, therefore increasing landslide risk, rather than other volcanic hazards.
