Document Summary
near japan there is a pacific plate which caused the earthquake. extremely dangerous area around the rim, epicenter is about 80km offshore. Japan moved 25m due to the earthquake in less than an instant, moved east. moved 25m in one go because the plates were locked and then they were released; were under a huge amount of stress which caused such a huge earthquake. plates should move about 2. 5cm per year. The recurrence intervals for these super quakes are about a thousand years. Japan goes east and the pacific plate underneath goes west. killed people because the vertical uplift which was like tilting up the ocean floor which went west to japan which caused a tsunami. The edge of the plate springs up from being dragged then the earthquake happens and the plates becomes unlocked and the overriding plate comes up. different fossil types can show evolutionary change through time.
