Short summary
Groundwater extends to the base of the Kanto Plain, some 3,000 m below sea level. Much of the Kanto Plain surface is at sea level. By the early 1970’s, local overdraft of groundwater resources caused major ground subsidence. The lowlands around Tokyo subsided to 4.0 m below sea level. Local government led to installation of about 500 monitoring wells and about 5000 bench marks by the 1990’s. Many of them are still working with new monitoring system. Long-term monitoring is important.
