← GeographyWhich hazard results from excessive outgassing within a volcanic dome?
A)Potential for lateral dome collapse✓
B)Rapid lahar formation during eruption
C)Increased viscosity blocking vent system
D)Depletion of volatile tephra quantities
💡 Explanation
Lateral dome collapse risk increases because increased outgassing destabilizes external structure material via elevated pore pressure effects; therefore collapse becomes likely, rather than other eruption-related problems, which might not affect instability.
