Which seismic hazard intensifies due to soil liquefaction along transform fault zones during an earthquake?

A)Ground subsidence affecting infrastructure
B)Tsunami generation from seafloor uplift
C)Pyroclastic flow propagation distances
D)Landslide frequency in mountainous regions

💡 Explanation

When seismic waves pass through saturated granular soils, liquefaction occurs because pore water pressure increases, reducing soil strength, leading to ground subsidence that can severely damage infrastructure built on it. Therefore ground subsidence and infrastructural damage result, rather than tsunami generation, pyroclastic flows or landslides which involve different triggering mechanisms.
