Which process amplifies ground shaking during earthquakes in areas with thick unconsolidated sediments?

💡 Explanation

When seismic waves pass through unconsolidated sediments, liquefaction can occur because the soil loses its strength, leading to soil resonance that amplifies the shaking. Therefore liquefaction-induced resonance results, rather than refraction, confining pressure reduction or wave conversion, which occur with differing conditions and mechanisms.
