Document Summary
Geo 303 lecture 14: earthquakes and seismology, chapter 16: Earthquakes and faults: earthquake: seismic event generated by a sudden shift or rocks across a fault, rocks under stress fail when stress exceeds strength. Strain results from stress: when stress grows across a fault or shear plane, rocks bend until they can no longer resist and then break causing a fault rupture, elastic rebound theory (h. f. reid) Stress builds across a fault or plane of weakness, rocks bend until they can no longer resist. Blocks slip suddenly, rocks snap back into place, and stress is temporarily relieved: different types of faults: Normal fault: things are pulled apart, block sliding down the middle. Reverse fault: things are being compressed, one is slipped up relative to another. Strike-slip fault: forces are horizontal, two plates are sliding along each other. Transform fault: contact between two plates, that slide horizontally past one another, commonly connected two mid-ocean ridges.
