Subsidence

The subsidence hazard in Japan has actually greatly decreased over the years thanks to new laws and ordinances that restrict groundwater pumping in soft ground.  Although there has been a slight increase from the recent low due to the nation-wide dry spell Japan is experiencing.  but they continue to protect their citizens from threats like sinkholes by placing informative signs to make citizens aware of dangerous areas and enforcing their ordinances on pumping ground water in sensitive areas.
