Document Summary

Geology 106: week 5, lecture 13: surface faulting, ground shaking, ground failure, tsunamis, fires, disease (disruption of water supply, e. g. cholera, human induces seismic hazards. Human-induced seismic hazards: dam construction fault (earthquakes can happen, loading of earth by water changes the stress below on, water infiltration below the dam can lubricate faults (earthquakes can happen + possible dam failure e. g. Malpasset dam in frejus, france: mining, the rocks will squeeze into the newly opened space due to release of pressure. Threat of rockburts (e. g. in sudbury ontario: pumping water underground, water pumping in denver colorado (quantity of water injected into the earth resulted in more earthquakes) Possibility of earthquake control: fracking (fraccing): hydraulic fracturing. Some are inactive, has not moved in the past 2 million years. Some are active has moved in the last 10,000 years. Yes, there are faults in the kingston area. All the way from small ones and very big oes (like the st.
