Document Summary
Earthquake is measured by magnitude, release of energy. A fault is a fracture, a crack in the earth across which the two sides relative to each other. Plates can move by slip which moves side ways of each other, Hypocenter is a deep point, everything starts. Shallow is everything above 140 km inside earth, Shallow is more dangerous because it is close to earth surface therefore it carries higher impact on surface. Epicenter is vertical up to the surface. Surface rupture is the only tiny area with line on fig 3. 2. The study of seismology is use to measure earthquake. Wavelength, period, frequency: involves low and high frequency, it carries certain infraction, amplitude: doing up and down. Attenuation: some of the wave depending on the frequency it can reduce the amplitude. green is going slow so it is low frequency, long distance amplitude is still seen as a wave.
