EESA06H3 Lecture Notes - Lecture 3: Fault Scarp, Heat Flux, Geomorphology
Document Summary
It is found in area called abduction where plates are moved together towards each other, so collision of this cause the rocks to move up. Other ways of rocks coming to the surface is by volcano and through meteorites. Slide 2-2: deepest drill hole anywhere on the planet is about 13km. There are physical limits to the depth we can measure because of geothermal heat flux. Steel which we use for drilling starts getting soft as we go down so we use cold fluids inside it to cool it continuously. Slide 3-2: focus-the location where the energy is generated and earthquake begins. The ground ruptures at this spot, then seismic waves radiate outward in all directions. Focus can be any depth down to about 700km. Epicenter-the point on the earth"s surface located directly above the focus of an earthquake. Beyond 700km is too hot where steel can become plastic.
