Seismic Damage and Influence to Industrial Facilities in the 2016 Kumamoto Earthquake

Abstract

In order to clarify the seismic damage of machines and equipment, and influence on the industrial facilities in the 2016 Kumamoto Earthquake, the seismic damage investigation mainly based on the questionnaire survey was conducted under the Japan Society of the Mechanical Engineers. From the result of the questionnaire survey, the failure at the fixing or the support of machines were reported, and it seems that the most of the seismic damage observed in the 2016 Kumamoto Earthquake were due to the large seismic motion. 46% of the questionnaire respondent prepared the emergency manual for the seismic events, and most of them said that it was useful in the 2016 Kumamoto Earthquake. Some future issues for the improvement of the seismic safety in the industrial facilities are discussed based on the questionnaire survey, as well as the investigation method for the seismic damage of the industrial facilities.
