Document Summary
If sf > 1, then safe or stable slope. If sf < 1, then unsafe or unstable slope: driving and resisting forces determined by the interrelationships of the following variables: Historic data: landslide hazard inventory map. Grading code from the least stable to the most stable: application of geologic and engineering knowledge before any hillside development, preventing landslides. Drainage control: reducing infiltration and surface runoff. Slope supports: retaining walls or deep supporting piles: avoiding landslides. October 2, 2017: short lived events, globally kill the most people, greatest loss of life, often defined in terms of moment magnitude (reflects the amount of energy released by the earthquake) Slip rate: how much slip (fault movement) over a period of time (e. g. , 1mm/yr) Low buildings = higher natural frequency body waves tend to vibrate low buildings. Tall buildings = lower natural frequency surface waves tend to vibrate tall buildings.
