It also requires consents from the Environment Agency "for water management, excavation below the water table and similar things".

The flames worsened when the water table dropped, which in turn exposed flammable carbon-rich soil.

Trees with access to shallow water tables "greened up" during drought, the researchers found, while trees over deeper water tables experienced more foliage browning and tree death.

If the subsurface magma level fell below the water table, scientists reasoned, groundwater flowing in from above it could spark a steam-driven eruption.

The new technique will map the top of the aquifer, called the "water table," spanning areas as large as hundreds of kilometers using a radar mounted on a high-altitude aircraft.
