Heavy equipment like generators and water mains must be designed to withstand an earthquake, according to a US government report published on Wednesday.
The USGS, the government agency that oversees earthquake safety, said in a report that it had reviewed more than 5,000 reports of the 2011 San Andreas Fault shaking.
“We have documented the risks associated with the use of hydraulic fracturing, or fracking, as well as the risks posed by wastewater injection,” the report said.
The report said that while hydraulic fracturing can help to reduce the amount of energy required for fracking operations, it is still a “critical step” in reducing the amount and volume of wastewater injection.
“The risks of wastewater injections to natural systems are not well understood, especially the risk of induced seismicity and associated earthquakes,” the USGS said.
“While some of these risks are well understood and may be mitigated through design and implementation of appropriate infrastructure, others are less well understood.”
Hydraulic fracturing involves injecting water and chemicals at high pressure into the ground to release trapped gas and oil.
In the process, fluids such as water and oil are released and rock is fractured.
The resulting fluids are then used to create natural gas or oil, and are used to supply power and water to industrial or industrial facilities.
The risk of earthquakes in Texas is one of the highest in the United States, according the US Geological Survey.
On Tuesday, a magnitude 6.1 earthquake struck just after midnight (20:00 GMT) in the city of Lubbock.
It was the second largest earthquake to hit the region since 2003.
