Which outcome worsens when cooling felsic lava creates a lava dome with a high aspect ratio?

💡 Explanation

Increased pyroclastic flow results because dome aspect ratio intensifies gravitational instability, enabling cohesive blocks to detach, thereby triggering block-and-ash flows, rather than promoting stability or eruption changes, because cooler magma increases internal dome friction.
