On the other hand that very divide, once bridged, led to a successful evacuation operation in the case of cyclone Phailin. It is thus important to study the linkages between science and […]

Liquefaction of Soil During Earthquakes

Earthquakes cause liquefaction of soil, transforming granular material from a solid to a liquefied state as a consequence of increased pore-water pressure and reduced effective stress. The generation of excess pore pressure under undrained loading conditions is a hallmark of all liquefaction phenomena. This occurrence was brought to the attention of engineers more so after […]
