With California introducing the Sustainable Groundwater Management Act in 2014, new estimations of subsidence based on water usage plans have revealed that stretches of the California Aqueduct are still at a substantially high risk of subsidence. These projections range from 10-15 feet of subsidence in the most at risk areas. [16]
In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2] Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured. [3] [4]

Rancho Palos Verdes, a coastal community in the Los Angeles area, could be described as a geological ticking time bomb. The affluent city sits atop steep cliffs overlooking the Pacific Ocean that ...
When groundwater is extracted from an aquifer, a cone of depression is created around the well.As the drafting of water continues, the cone increases in radius. Extracting too much water (overdrafting) can lead to negative impacts such as a drop of the water table, land subsidence, and loss of surface water reaching the streams.
At around 6:30 p.m., the Eaton Fire erupted in the Altadena area, north of Pasadena, and has now churned through more than 14,000 acres and has been 35 percent contained. At 10.29, the Hurst fire ...
In the Texas Panhandle and western Oklahoma, the Smokehouse Creek fire in February 2024 was the largest in state history. It killed two people, burned more than 1.2 million acres and destroyed ...
This is a list of Superfund sites in California designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up ...
