Residents in Koronadal City, South Cotabato experienced soil liquefaction after a magnitude 7.8 earthquake hits the Mindanao islands on 8 June 2026.
In a post by Bonjing Official, some parts of land in residential areas of Koronadal City spewed water this morning, a tell-tale sign of soil liquefaction in the area after the said powerful earthquake.
Soil liquefaction occurs when water-saturated, loosely packed granular soil—like sand or silt—temporarily loses its strength and stiffness due to intense shaking, behaving like a thick liquid rather than a solid.
It is a major hazard in earthquakes.
