Algeria Water comes out in the places of cracks in the ground, created by the M5.2 #Earthquake yesterday in the eastern province of Mila, Algeria It’s sign of Soil Liquefaction. Soil liquefaction, also called earthquake liquefaction, ground failure or loss of strength that causes otherwise solid soil to behave temporarily as a viscous liquid.
