Document Summary

Ea(cid:396)th(cid:395)uakes: earthquake definition, a sudden shaking motion of the ground, caused by the propagation of energy (travel of seismic waves) through the earth (ie: Due to climate change, melting takes place at the base and top of the glacier so the ice moves faster, causing more earthquakes: fracking areas: technique for getting petroleum, gas, and oil from rocks. This generates a lot of toxic wastewater that are gotten rid of through injection wells in the ground. Fault movements: not all major faults creep. Highest intensity is near the fault, as well as in muddier sediment areas: seismic gaps: areas where we expect earthquakes to occur in the future. Areas where earthquakes have occurred have already shown a shift in the rocks downwards. Large earthquakes: large areas may slip during an earthquake, bigger faults make bigger earthquakes that last longer. The designation of the shocks can only be possible after the event.
