Ch.5, Sec.3 – Earthquakes & Society - seismologists cannot predict when earthquakes will happen, but we can use earthquake hazard maps to predict where they will most likely occur Earthquake Hazard Earthquake Hazard

Ch.5, Sec.3 – Earthquakes & Society - earthquakes are more likely to occur in California, Oregon, & Washington because they lie on the San Andreas Fault - earthquakes are more likely to occur in Montana & Wyoming because they lie on the super-volcano called Yellowstone N.P.

Ch.5, Sec.3 – Earthquakes & Society - when earthquakes occur at plate boundaries, the pressure is relieved in that spot along the fault (unfortunately, this means pressure is building up in another spot though!!!) Earthquake Forecasting Earthquake Forecasting - the majority of yearly earthquakes are light to very minor

Ch.5, Sec.3 – Earthquakes & Society  gap hypothesis – a hypothesis that states that sections of active faults that have had relatively few earthquakes are likely to be the sites of strong earthquakes in the future  seismic gaps – the areas along a fault where relatively few earthquakes have occurred

Ch.5, Sec.3 – Earthquakes & Society Earthquakes and Buildings Earthquakes and Buildings - many of the buildings in major cities along plate boundaries are retrofitted with base isolators, cross braces, dampers, and active tendon systems to prevent structural damage! - the safest place to be during an earthquake is outside of a building!

Ch.5, Sec.3 – Earthquakes & Society Tsunamis & Avalanches Tsunamis & Avalanches - giant ocean waves, called tsunamis, can be created by ocean floor earthquakes - large amounts of moving snow, called avalanches, can be created by earthquakes

Ch.5, Sec.3 – Earthquakes & Society actual Tsunami actual Avalanche

Ch.5, Sec.3 – Earthquakes & Society real Tsunami

Ch.5, Sec.3 – Earthquakes & Society fake Tsunami

Ch.5, Sec.3 – Earthquakes & Society What are some of the hazards you might face if an earthquake occurred in the following situations: What are some of the hazards you might face if an earthquake occurred in the following situations: 1. asleep in bed? Answer: collapsing building 2. swimming at the beach? Answer: tsunami 3. snow skiing? Answer: avalanche
