How movement along a fault generates tsunami
Did you know?
WebA magnitude 7.0 earthquake along the Denali Fault generated a massive rockfall into the bay, which produced a 1,700-foot tsunami. However, the bay contained most of the energy, and thus a major catastrophe was averted. Nevertheless, another such event is occurring in Glacier Bay, Alaska, which is a significant tourist attraction for cruise lines. WebAfter an earthquake, rocks snap back elastically to their pre-stress condition. TRUE Because they travel through the earth, body waves cause the most structural damage during earthquakes. FALSE P waves can travel through solids only; S waves can travel through both liquids and solids. FALSE
