Small-Titan, an array system deployed in Sendai City and used for observing strong ground motion succeeded in obtaining strong ground motions at many sites during the 2011 Great East Japan Earthquake. Small-Titan installed in 1998 to investigate local site effects on strong ground motions consists of 20 observation sites with different soil conditions and has obtained over 500 records of various kinds of earthquakes since its installation. The 2011 Great East Japan Earthquake caused severe damage in Sendai City, including that from a tsunami. One site of the Small-Titan system was also hit by a tsunami. This paper describes the background leading to the success of the records of observation of strong motion by Small-Titan for this earthquake and outlines characteristics of records.
