Document Summary
1. 1 megathrust earthquakes thrust fault- one rock block is thrust up and over another by compressive stress on the system. Submerged coastlines: recognized by drowned vegetation within the sedimentary sequence, can be dated to discover tsunami date aka earthquake, it is the rapid release of stress that pops the coastline under water. Imamura-iida scale: tsunami magnitude is calculated as a function of the maximum wave height measured in the open ocean. 1. 2. 4 how do landslides, volcanic eruptions, and asteroids. 1. 2. 7 pacific tsunami warning center (ptwc: detect/locate major earthquakes in the pacific region, determines whether they have generated tsunami to provide timely and effective info and warnings to minimize the hazards of tsunami. 2. 1 cascadia plate tectonics: the west coast of north america has every type of plate tectonics thus every category of earthquake is there somewhere, kula and the farallon were subducting under the north.
