Which risk increases when strike-slip motion along an undersea transform fault displaces the seafloor?

💡 Explanation

When strike-slip motion occurs underwater, sudden vertical displacement of the seafloor can trigger tsunami generation because of the kinetic energy transferred to the water column. Therefore a tsunami results, rather than methane release, acidification, or erosion, which involve different geophysical mechanisms unrelated to displacement.

• Which effect on stream drainage patterns is caused by strike-slip offset along a transform fault?
• Which effect is most significantly magnified in delta regions when artificial levees are constructed along major distributaries?
• Which mechanism causes the formation of explosive stratovolcanoes at subduction zones?
• Along subduction zones, which mechanism primarily controls variability in explosive volcanic eruption intensity?
• Which mechanism dictates volcanic eruption explosivity when magma's silica content rises above approximately 65%?
• Which risk increases when an earthquake occurs in a region with unconsolidated, water-saturated sediment?
