[MP3-08] Fragility curves for economic losses in industrial sectors after strong wind disaster: A case of 2018 Typhoon Jebi

Hasi (Kyoto University)

This study proposes strong wind disaster fragility curves for economic losses of industrial
sectors, which represent conditional probabilities of reduction of economic losses given a
strong wind. This is an extension of the method of fragility curves for structural vulnerability.
The present paper conducts a questionnaires survey regarding economic impacts on
business activities of firms after the 2018 Typhoon Jebi and estimates the functional fragility
curves by using the data. The estimation is conducted for different industrial sectors and
the result imply that functional fragility curves are different between sectors. The
information of functional fragility curves in this paper are helpful for conducting quick
estimation of economic impacts on business sectors in case of large scale strong wind
disaster. In addition, the functional fragility curves can be used by individual firms for
understanding the potential impacts of future disaster on their businesses and preparing
countermeasures for the risk such as business continuity plan (BCP).
