🌎 Earthquake Liquefaction - 2D Soil Column (Seed-Idriss Safety Factor and Pore Pressure Build-Up)

2D companion of the earthquake-liquefaction lab: a layered saturated sand column shaken by a design earthquake, with cyclic stress ratio, SPT-based resistance, factor of safety against liquefaction by depth, pore-pressure ratio build-up and a surface structure that sinks.
