Which risk increases sharply within unstable lava domes?

💡 Explanation

Catastrophic dome collapse increases because the internal pressure and weakening of the dome structure exceeds its structural integrity allowing rapid outward and downward movement during gravitational instability. Therefore, an avalanche, rather than increased insolation, occurs abruptly.
