Abstract
In order to investigate behaviors of buildings during earthquake due to accumulate observation data, low-cost seismometers are produced and checked. Using data by shaking table test results and observed earthquake motions, the accuracy verification of low-cost seismometer is conducted through comparison with servo-type seismometer. The low-cost seismometers were installed in a detached house and earthquake motions have been observed since about three years ago. In these periods, many earthquake motions have been obtained to discuss characteristics of the earthquake motions at the site and characteristics of dynamic behavior of the detached house. The low-cost seismometer has been operational for about four years since the low-cost seismometer was produced. From the result, it is confirmed that the low-cost seismometer has enough durability.
