Magnitude 7.0 - Haiti Earthquake 2010 January 12 21:53:09 UTC See USGS for more information: www.earthquake.gov . Epicenter: ~15 km from Port-au-Prince (2-3 million people) Enriquillo-Plaintain Garden Fault system

“Mechanics” and “Thermodynamics” Govern Earthquakes “Displacement” (or rupture) along a fault is caused by “forces” generated within the Earth by nuclear decay. Within an extended body, forces are usually called “stresses” – with units of force/area. Earthquakes radiate “energy” as “waves” , as well as release “heat” energy and do “work” on the Earth by deforming it. Deformation prior to rupture is commonly called “strain” – which is unitless. Faults operate in accordance with “Newton’s Laws” and, of course, conserve “energy”, “momentum”, and “angular momentum” . Earthquake size is quantified by magnitude, which can be converted to “energy” .

    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.
