California drought: Joaquin Valley sinking by 2 inches every month

The video discusses the increased consumption of groundwater due to drought conditions, leading to the pumping of groundwater from deep aquifers. This process reduces water pressure and causes the clay particles in the Corcoran clay layer to compact, resulting in the collapse of the ground above. Once compacted, the clay cannot be repaired, permanently reducing future water storage capacity. Subsidence has been observed throughout the San Joaquin Valley, with significant sinking near Corcoran and El Nido.

Explain the relationship between drought and groundwater consumption.

What is the significance of the Corcoran clay layer in groundwater management?
