Which hazard increases with steeper cooled lava dome slopes?

💡 Explanation

Pyroclastic flow generation increases greatly because gravitational instability leads to dome collapse through the mechanism of mass wasting; therefore, a pyroclastic flow results, rather than slow effusion typical of lava domes reaching gentler angles.
