Liquefaction Experiment Apparatus


【Product Description】

Table-top vibration generator to observe how simulated seismic waves cause soil liquefaction phenomenon and damage to an on-board mock building.

【Overall Advantages to Users】

  • Generates oscillating motion similar to the horizontal seismic vibration (surface wave) represented as a pseudo-sine wave.
  • Designed to observe how a mock tall building shakes along with the amplitude and how soil liquefaction phenomenon occurs during an earthquake.
  • Contains accessories suitable for reproducing and observing soil liquefaction phenomena in addition to the “Seismic Waves Reproduction Apparatus, K50-1207-W0”.


  • Seismic phenomena, seismic waves, earthquake
  • Long-period vibration and short period vibration of earthquakes
  • Liquification of the ground caused by an earthquake

  • Designed to learn about phenomena of natural disaster in the classroom by reproducing seismic activity to observe:
    • the process of how a tall building (or a house) collapses, and
    • the mechanism of and the damage from liquefaction (note: accessories to reproduce liquefaction are included).

【To teachers】

  • Designed to reproduce the process of how a building shakes and collapses through teacher’s demonstration using the model building of seven (7) stories that comes with the product.
  • Earthquake proof assessment of self-produced mock building and/or its foundation possible.
  • Observation of damages caused by soil liquefaction phenomena possible.

【To students】

  • Easy to observe, in person, the process of how a building collapses and how liquefaction occurs.
