subterranean

China is setting out to chart an exquisitely detailed subterranean atlas across the country’s vast expanse.

Volcanoes set off a cascade of chemical changes in the environment that make their way to the subterranean rock.

There would be subterranean and above-ground parking, and at least 20% of the units are expected to be designated as affordable with subsidized rents.

That can cause the dynamic subterranean forces below volcanoes to produce increased quantities of magma, leading to more frequent eruptions.

By the early 2010s, this long subterranean decline finally became impossible to ignore as drought dried up wells, land sank and canals collapsed.
