Right after the Great East Japan Earthquake in 2011 many public elementary and middle schools served as emergency shelters for people who had lost their homes. Some of these schools
Pre-slip is defined as the abnormal crustal changes just before an earthquake, which it has been said in Japan, would be impossible to detect by the existing measurement methods. If one can detect pre-slip a few days before an earthquake, it would be really helpful in alerting people to be better prepared for evacuation. The pre-slip can become clearer if one checks the daily height changes over two years at critical points. Figure 11 shows the daily changes of X, Y and Z over two years at Kesennuma at the most critical location in which dramatic falls in the X, Y, Z values can be seen on the last three days (March 8, 9 and 10) before the Earthquake. In particular, the largest fall of 3 cm occurred in the Y values over these three days. Figure 12 shows very clearly the height changes at the 10 worst points with large preslips on the last three days. A reason why the Y values showed the maximum pre-slip can be explained as follows. Firstly, the Pacific coast of the Tohoku District which is almost parallel to the Japan Trench (a border between the Pacific Plate and the North American Plate), and the direction of which almost coincides with that of the Y axis as shown in Figure 13. Secondly, the increase of the Y value means a movement upwards and to the west with an oblique angle to the horizontal direction, while a decrease of the Y value means a movement downwards and to the east with the opposite direction of the oblique angle to the horizontal direction, since the Pacific coast at the Tohoku District is located roughly on a longitude meridian of E 142°and 52°east along the Y axis. The actual movement of the Pacific coast at the Tohoku District during and after the Great Earthquake consisted of a south-easteast horizontal movement and downward vertical movement, which is almost equivalent to the decrease of Y values.
