Abstract
The Noto Peninsula (Noto-Hanto) earthquake occurred at 9:41 on JST on March 25, 2007 and it had a
magnitude (Mj)of 6.9on the magnitude scale of Japan Meteorological Agency. The earthquake killed one person
and injured more than 359 people. The strong ground motions were quite large in the epicentral area with high
frequency components.The earthquake induced many slope failures along the steep shores and mountainous terrain.
Embankment failures and settlements were widespread particularly along Noto Toll Road, rivers and creeks. The
embankments facing the east were failed along a section of the Toll Road between Noto Airport and Yokota
Interchanges (Figure 1). This article describes the fundamental characteristics of the 2007 Noto Peninsula
earthquake with an emphasis of geotechnical damages and their evaluations.
