EGGS 107 Lecture Notes - Lecture 3: Rayleigh Wave, S-Wave, Glossary Of Tennis Terms
Document Summary
Faults-breaks in rocks where pressure was released and the rocks are displaced. Foot wall is high, hanging wall is low. The block above the fault (the hanging wall) moves up relative to the block below the fault (foot fault) Where the rupture first hits the surface. Important for earthquake warnings; small bits of energy and cracks before the biggest main quake. Result of the shear wave reaching the surface. Buildings could of been made of weaker material than another. Largest displacement in mm on the seismograph that"s 100km from the epicenter. Richter scale doesn"t work on earthquakes 07. Richter scale is now ml (magnitude local) Rigidity of the rock (how strong the rock is) How big was the fault movement area. Transform fault max out at about an 8. In high rise buildings, there"s usually first floor damage because the first floor is attached to the ground so the other floors move at different rates.
