Document Summary

A submerged mass of continental crust that sank after breaking away (rifting) from australia. A concept that is still poorly understood. When two plates converge, one plate containing oceanic lithosphere descends beneath the adjacent plate, thus consuming the oceanic lithosphere into the earth"s mantle. The base of how far you are away from the fault to the epicenter. Closer you are to the fault, the more damage. When the earthquakes releases its energy / as the energy spreads, the energy dissipates as it gets further. Ground you"re actually standing on and what it"s like. Fine grain sediment, silicate minerals, and lots of water in between those minerals (mud) Sand and gravel (more shaking since material is loose) Looser, softer substrate = more shaking, more damage. Soft substrate + further away = more shaking than hard substrate + further away. Actual movement of the ground surface (when ground breaks during eq)
