GEOL 2207 Lecture Notes - Hypocenter
Document Summary
Be familiar with earthquake processes such as faulting, tectonic creep, and the formation and movement of seismic waves. Know which regions are most at risk for earthquakes and why. Know and understand the effects of earthquakes such as shaking, ground rupture, tsunami and liquefaction. Identify how earthquakes are linked to other hazards such as landslides, fire, tsunamis. Know how human beings interact with and affect earthquake hazards. Understand how we can minimize seismic risk, and recognize adjustments we can make to protect ourselves (building code) Over 2 million deaths in last 100 years. Depends on building codes, how deep earthquakes was, population. Results from rupture of rocks along a fault: energy released in the form of seismic waves spreads in all direction. Faults: fractures in along which displacements occurs. Focus(hypocenter): source location of the earthquake on the fault. Epicenter: point on earth"s surface directly above the focus. Seismic: of, subject to, or caused by an earthquake or earth vibration .
