Abstract

According to the book "Earthquake Can Be Predicted", which studied earthquakes of M3.0—M4.0 to M8.0, since very beginning on Chinese Seismic Network via elect-communication lines, in about half a century duration, in view of earthquakes in large scale, the Chinese seismic pattern is studied in the globe scale seismic framework. It is recognized that not anywhere and anytime can a large earthquake occur. Large earthquakes occur in their special temporal and spatial windows. The intersection between earthquake stripe and earthquake circularity, the difference in seismic activities; the earthquakes in great depth and the events outside the Earth are the main factors that control the temporal and spatial windows of the large earthquake occurrence. There are three types of intersections between earthquake stripe and earthquake circularity: stripe with stripe; circularity with circularity; and stripe with circularity. According to the features of the gaps, it is recognized that the gap may be caused by buckling on its earth layer. Therefore, one has to pay attention on the difference between active and quiet regions. Since a large earthquake very often occurs at the time node of a special condition, related with events outside the Earth, one should pay attention to these events that are not random in nature. The main factors that control the temporal and spatial windows of large earthquake occurrences, as described in this paper, were verified in a earthquake of magnitude of 9.0 occurred on 11 March 2011, off the Pacific Coast of the northeastern part of the Japanese main land (Tohoku Region).
