Turbidity Current

Earthquake

Earthquakes, ground motions, landslides, turbidity currents, and turbidites:• Seismic Forcing of Slope Stability

• Earthquake creates Ground Motions• Ground Motions trigger Landslides• Landslides transform into Turbidity Currents• Turbidity Currents leave deposits called Turbidites

Submarine Landslides

Ground Motions
