NASA radar shows Mexico City's rapid subsidence threatening water and infrastructure

Mexico City is sinking at up to about 0.8 inches per month (roughly 9.5 inches per year) due to over-pumping of its ancient aquifer. NASA’s NISAR radar maps reveal the pace of subsidence, accelerated by dense development on clay-rich soils, and the ground drop is fracturing roads and infrastructure while threatening the city’s water supply for about 22 million residents, raising concerns of a potential day zero if groundwater loss continues.

Hidden Freshwater Reservoir Revealed Beneath the Great Salt Lake

Hidden Freshwater Reservoir Revealed Beneath the Great Salt Lake

University of Utah researchers used airborne electromagnetic surveys over Farmington Bay to map beneath the Great Salt Lake and found freshwater permeating sediments up to about 4 kilometers deep, indicating a substantial subsurface reservoir. The study linked reed‑filled mounds to freshwater breakthroughs and mapped the potential volume, though the full extent remains unknown and requires more surveys. If confirmed, this groundwater could help wet dust hotspots and contribute to water resources without overly perturbing the lake system.

Ancient Freshwater Deposit Discovered Beneath Sicily

Ancient Freshwater Deposit Discovered Beneath Sicily

Geologists have discovered a massive deposit of ancient freshwater deep below the mountains of Sicily, estimated to contain 17.5 cubic kilometers of water. The deposit, trapped for around 6 million years, could potentially provide a solution to the water scarcity issues faced by arid lands along the Mediterranean coastlines. The discovery was made by analyzing maps and data from previous surveys looking for oil deposits. The researchers believe the water may have been trapped during the Messinian salinity crisis, a geological event that dried up the Mediterranean Sea basin. This finding has significant implications for addressing water scarcity in southern Italy and other regions in North Africa.

Ancient Subterranean Pool Found in Sicilian Mountains

Geoscientists have discovered a deep underground pool of fresh water beneath the Sicilian mountains, estimated to be around six million years old. The researchers used publicly available data from oil exploration efforts to study the groundwater in the Gela formation. They found evidence of an aquifer holding approximately 17.5 cubic kilometers of water, which they believe was trapped during the Messinian salinity crisis. The rainwater that accumulated underground was likely soaked up by carbonate rock, and the researchers identified the Malta Escarpment as a probable conduit for the ancient rainwater.

Ancient 'fossil groundwater pool' found beneath Sicilian mountains

A "fossil groundwater pool" containing 4.2 cubic miles of fresh water has been discovered deep beneath the Hyblean Mountains in Sicily, Italy. The water, trapped underground during the Messinian salinity crisis 6 million years ago, became sealed off from the Mediterranean Sea by sediments and mineral deposits. Researchers believe the water could potentially alleviate water scarcity in Sicily and hope the discovery will inspire further exploration of deep groundwater reserves in other parts of the Mediterranean.
