In Chiba Prefecture, a Japanese Meteorological Agency (JMA) seismic intensity scale (IJMA) of six-minor was recorded at Narita, Inzai-sasagami and Inzai-ohmori. Tsunami damage on the Pacific side and liquefaction damage on the Tokyo Bay side and along the Tone River of Chiba were severe. In addition to this damage, there was building damage by liquefaction. We report here on the building damage in Chiba Prefecture. Key Words: Great East Japan earthquake, building damage, Chiba Prefecture INTRODUCTION The 2011 Tohoku-chiho Taiheiyo-oki Earthquake, Japan that occurred on March 11 2011, caused severe damage over a wide area of Japan including Chiba Prefecture.
