Earthquakes 8 October 9, 2007 I. Moving into Earthquakes a. More physics/equations will be involved II. Waves a. Seismic waves: i. Important cuz they cause all the damage in earthquake and also provide means by which to see how interior of earth looks like 1. use them as x-rays b. Definitions; i. See figure one in drawing notes: explaining parts of a wave ii. Figure B: explains that period is the time between successive peaks 1. timing between one wave and next wave iii. Frequency—how many waves go by in given time 1. f= 1 / T a. so its basically the inverse of “period” 2. EX: so if period of a wave is .5 second, then the frequency is 1/.5= 2 i. One cycle / Second = a hertz (hz) iv. Velocity (v) 1. V = Frequncy * Wavelength a. In EQ, use km/ second 2. Frequency = V/ Wavelength i. EX; 800km/hour divided by 200 km = 4 cycles per hour ii. This applies to tsunamis c. Tsunamis (tidal waves) i. Look from shore that a tide is coming in, except that its very tall and fast; hence “tidal wave” 1. tsunamis are not driven by wind like tides are a.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
