ABSTRACT: Japan has experienced many large-scale natural disasters, such as
earthquakes, typhoons accompanied by heavy rain, and landslides. Based on data
for the damage caused by four recent major earthquakes in Japan, we investigate
the trends in the number of evacuees and evacuation centres after these
disasters as well as the restoration processes for public utilities such as
electricity, gas, water, and communication lines. We compare the restoration
speeds and trends of the damaged infrastructure systems. We also propose
various mathematical models to approximate the recovery trends using both
evacuee-related data and damage recovery process data. These results can be
used to design natural disaster mitigation policies not only in Japan, but also
in other countries. The results of various statistical data analyses and
mathematical modelling techniques are applied to provide policy suggestions.
