← GeographyWhich phenomenon initiates turbidity currents along submarine fault scarps during seismic activity?
A)Liquefaction of sediment✓
B)Seafloor methane hydrate release
C)Tsunami wave propagation
D)Erosion by thermohaline circulation
💡 Explanation
When seismic shaking occurs near submarine fault scarps, liquefaction of sediment happens because grain structure weakens due to increased pore pressure, initiating downslope movement and turbidity currents. Therefore liquefaction results, rather than hydrate release, tsunami propagation, or thermohaline erosion that depend on different triggers.
