Many factors can contribute to subsidence, including building, mining, tectonic shifts, earthquakes, and natural soil consolidation, where soil is pressed closer and becomes more dense over time. But “one of the most common causes is groundwater extraction and dozens of coastal regions and cities are sinking at a worrying speed,... read more...

New research has uncovered new evidence to suggest that Earth is leaking gases from deep inside its mantle, even in regions without any volcanic activity. The study reveals that gases including helium and argon are slowly seeping hundreds of kilometres up through Earth’s crust. The highest amount of gas was... read more...

The gin-clear waters of the Kilsby sinkhole, a popular freshwater diving site, provide visibility of up to 65 metres. But water levels have dropped 1.5 metres between January and March 2025. It’s a long-term decline: the vast groundwater network in the limestone crust that straddles the border between South Australia... read more...

Previously untapped heat from a mine water treatment scheme in Wales is now being harnessed to provide low-carbon heating. The mine water is naturally warm due to geothermal energy from the earth’s crust and heat retained from its time circulating through underground rock layers and former coal mines. An innovative... read more...

The city of Bengaluru and its surrounding peri-urban areas have been grappling with severe groundwater depletion, driven primarily by over-extraction. The administrative focus remains largely on technical and financial fixes — laying pipelines, ensuring capital investment. Researchers argue that more emphasis needs to be placed on effective water resource management.... read more...

Land in South Africa has been rising at the rate of 2 millimetres per year, according to a recent report, thought to be due to hot magma rising from the Earth’s mantle. But, loss of water during droughts may have caused the earth’s surface to bounce up as an elastic... read more...

Pakistan’s agriculture sector is becoming increasingly dependent on groundwater due to multiple factors, including declining river flows, erratic rainfall, expansion of water-intensive rice and sugarcane crops, increased cropping intensity, and more recently, the widespread adoption of solar-powered tubewells that offer minimal operating costs, which encourages indiscriminate pumping of groundwater. But... read more...

Jeff Davies died unexpectedly on 3 May at the age of 75. Jeff was a hydrogeologist who spent his entire career putting ‘geology’ into ‘hydrogeology’. He would tell you that there was no point in trying to understand the hydrogeology of an area unless you first understood the geological setting... read more...
