Abstract：Under the background of globalization, the frequency of the major natural disasters is accelerating, with the major threat following. Earthquake is one of the major natural disasters. Although earthquake happened with a low frequency, the economic losses and casualties caused by earthquake are huge. It will be of great significance in reality and theory to do study on earthquake tendency. This paper analyzes the seismic data about MS≥6.8 nearly a century of Ecuador from the viewpoint of time and space, and further does the time symmetry analysis by using the butterfly structure and commensurability structure system and the law of the hypocenter migration about latitude-longitude and space. It comes to the conclusion that there is a strong earthquake signal during 2015 and 2016. And it is likely to happen MS≥6.8 earthquake in 79o-81oW, 1oN-1oS of Ecuador. Theresearch can offer some reference for the trend analysis of earthquake disasters and provide some enlightenment for future research.
