The earthquake that struck Japan’s coast a month ago gained national attention for the damage caused by the tsunami that was caused by the earthquake. Japan’s coast is subject to multiple earthquakes each year with tremors and aftershocks following. The quakes are bound to have an effect on the growth and development of Camellia sinensis, the tea plant, which is one of the most important exports of Japan. Due to the time restraints of this project, C. sinensis were not tested, instead two week old Phaseolus vulgaris were used to show the effects of constant agitation which might mimic the effects of the tremors of an earthquake. This study is meant to see what effects tremors may have on the growth and overall health of a plant. Our study found that the initial growth rate, based on height of a plant was noticeably stunted in the plants that were subjected to constant agitation. Our data also showed that the average percent growth of a plants total height during the five weeks of study was almost twice as great in the control plants than it was in the test plants.
