This study researched characteristics of the transition in the number of refugees in shelters and the behavior of choosing shelters in the Earthquake Disaster. Results are follows. (i) The number of refugees in shelters exponentially decreases. The number of refugees in The Niigata Earthquake and The Northridge Earthquake is well represented by a simple exponential model. And a sum of two simple exponential model well represent them in some part of Kobe under The Great Hanshin - Awaji Earthquake Disaster. (ii) The degree of the damage to buildings and the velocity of the restoration may influence the transition in the number of refugees in shelters. (iii) The Huff model can express the refugees behavior of choosing shelters in certain areas of Kobe in The Great Hanshin-Awaji Earthquake Disaster.
