EESA06H3 Chapter 3: Chapter 3 Notes
Document Summary
The earth puts stress on the rock, and it bends (strain) Elastic rebound theory: the sudden release of stored elastic strain energy in rocks, causing movement along a fault. Tectonic forces act on a mass of rock over many decades. Damage to buildings depends greatly on the type of geological material it was built on and the type of construction. Can also calculate the amount of energy released; done by measuring the squiggles on a seismogram. Richter scale is open ended which means there is no earthquake too big or too small. Can also measure the seismic movement; determined from the strength of the rock, surface area of the rupture, and amount of rock displacement along the fault. Richter scale is logarithmic, so the difference between 2 consecutive numbers on the scale means an increase of 10 times the amplitude www. notesolution. com. This means that an increase of about 32 times of energy is released.
