Abstract

On March 11, 2011, the giant tsunami following the Great East Japan Earthquake brought damage to much of northeast Japan. The giant tsunami delivered a large volume of water to the area along the shore, resulting in a flood mark as high as 9.3 m. The tsunami resulted in the destruction of at least 129,483 houses, the partial destruction of 255,447 houses, and water damage to at least 35,945 residences, including 20,432 flooded above floor level [1]. As part of this study, we propose techniques for the detection of settled fungi contained in house dust and of adhesive fungi on surfaces such as under-floor joists. Findings show that contamination caused by fungi persisted in under-floor spaces even 2 years after the giant tsunami. Aspergillus and Penicillium were the most frequently recovered genera of fungal contamination on these under-floor surfaces. And the techniques used here to detect settled fungi (house dust) and adhesive fungi (tape-lift) are expected to find use in estimating the status of fungus contamination in indoor spaces.
