Which consequence results when a growing lava dome's structural integrity reaches its tensile limit?

💡 Explanation

Block and ash flows occur due to dome collapse because gravitational stress exceeds tensile yield, causing fragmentation via brittle failure, therefore producing hazardous flows rather than persistent effusive eruptions under low-stress conditions.
