Widespread damage was caused in eastern Japan as a result of the earthquake and tsunami which occurred in 2011 off the Pacific coast of Tohoku (hereinafter, the 2011 Tohoku Earthquake). A large tsunami struck the coastal area of eastern Japan and caused damage to buildings, breakwaters, tide embankments and river levees. The joint reconnaissance team of the Tohoku and Kyushu branches of the Japanese Geotechnical Society investigated the geotechnical damage in the south-central coastal area of Iwate Prefecture from the beginning of April to September 2011. This report summarizes the geotechnical hazards and the damage to port structures, roads, railways, river levees, and buildings caused by the earthquake motion and tsunami in the 2011 Tohoku Earthquake in the south-central coastal area of Iwate Prefecture. Major investigation areas are Kamaishi City (Koshirahama Port, Touni-Chou), the coastal area of Ofunato City (Sanriku-Chou Yoshihama, Sanriku-Chou Okirai), and Rikuzentakata City. In the 2011 Tohoku Earthquake, many people could not or did not evacuate from the tsunami. However, students at junior high and elementary schools started tsunami evacuation quickly, resulting in what is known as the “Kamaishi Miracle.” This study focused on the tsunami evacuation of children in Unosumai district, Kamaishi City.

A destructive earthquake struck the Kobe region on January 17, 1995, and a massive earthquake and tsunami struck eastern Japan on March 11, 2011. We present an overview of the casualty aspects of the 2011 Tohoku earthquake compared with those of the 1995 Kobe earthquake. In the Tohoku disaster, some water gates and seawalls saved some villages from the tsunami effects, though some did not. Based on these examples, we discuss the efficiency of soft and hard measures and consider their respective merits and demerits. The main causes of death in the Kobe and Tohoku EQs were, respectively, collapsing buildings and drowning in the tsunami. Although the time to death was very short in both cases, people often have more time to evacuate in the case of an interplate earthquake leading to a tsunami. Basic countermeasures against tsunamis include such hard measures as water gates, seawalls, and embankments. Soft measures need to be implemented in areas where hard measures are insufficient
