It occurs when saturated, loose, granular soils—such as sand or silt—are subjected to intense shaking. Factors Influencing Landslide Risk The likelihood and severity of landslides following an earthquake depend on a combination of geological and environmental factors.
Tsunami Generation and Rapid Water Surge After Earthquakes
Unlike normal ocean waves, tsunamis often do not crash dramatically but rather manifest as a rapid and seemingly unstoppable surge of water. When the ground stops shaking after a significant seismic event, the immediate danger often feels like it has passed.
The pressure of the shaking forces the groundwater upward, separating the soil particles and causing the ground to lose its strength and behave like a liquid. When an undersea earthquake causes the seafloor to abruptly uplift or drop, it displaces a massive volume of water.
Hidden Dangers Tsunami After Earthquake
Landslides and Debris Flows Among the most visually dramatic secondary hazards, landslides occur when seismic shaking destabilizes slopes that were previously stable. Roads, bridges, and underground utilities are also severely compromised when the solid earth they rely on turns fluid.
