From: The impact evaluation of soil liquefaction on low-rise building in the Meinong earthquake

Index Description Interpretation
GF0 No observable ground failure No settlement, tilt, lateral movement or sediment ejecta
GF1 Minor ground failure Settlement, D < 10 cm; tilt < 1°; no lateral movements
GF2 Moderate ground failure 10 cm < D < 25 cm; tilt of 1°–3°; small lateral movements (<10 cm)
GF3 Significant ground failure D > 25 cm; tilt of > 3°; lateral movement >25 cm
