“Shaken not stirred”: Mosaic sand – a semi-liquefaction phenomenon originating from strong earthquakes
The formation of mosaic sand, here as exemplified from a 0.23 km2 sand field at the coast of Nordland County in Northern Norway, is thought to be related to earthquake induced shaking, re-mobilization and partial (semi-) liquefaction of water-saturated, stratified fine and medium sand. It is therefo...
