U.s., California Residents Have Been Protesting Geothermal Exploration Will Lead The Earthquake?
Recently, a California geothermal exploration Project Local residents have been protesting
on the grounds that the project could trigger small earthquakes. As with the wind, Solar Energy , Tied for the major biomass New Energy One, clean and stable geothermal industry has been promising. Keep an eye on??
Located in northern California, from San Francisco, 2 hours north of where a drilling depth will reach 3,200 meters, produced using high temperature steam geothermal power generation projects have been protests by local residents, residents are worried the project trigger earthquakes, after all, experienced in the 20th century San Francisco in 1906 and 1989 earthquake.
Geothermal exploration and geological disasters, there is a connection do you? How to make exploitation of direction?
Drilling for water, will drill a bad crust?
"When the development of deep geothermal drilling, mining of water vapor actually adopted will have a certain influence of stratum structure, but the earthquake in particular, need the earthquake energy is orders of magnitude difference, are not comparable." Hydrogeology of Chinese Academy of Geological Sciences Environment Research Fellow, Research Director of the regional hydrogeology and groundwater system, said, "In addition, dozens of earthquakes in general in the ground, hundreds of kilometers deep beneath the earth, and our deepest geothermal drilling only more than 4000 meters." Technically, California and Basel, the project is to underground rock burst method to produce the steam injection pressure, while the majority of the geothermal project is extracted from underground steam and hot water, on the formation of smaller.
According to reports, more than 150 temperature geothermal resources are located in earthquake zones, such as California and Taiwan, Indonesia, New Zealand in the Pacific seismic belt, the Qinghai-Tibet Plateau in the Himalayan seismic belt, the crust and magma frequent activities of deep groundwater "burn" into high-temperature steam, or even directly to the surface forming hot springs. However, the activities relative to the earth, the human activities minimal. Such as geothermal power stations in Tibet Yangbajain that is put into operation in 1981, nearly 30 years, did not trigger earthquakes.
"The extensive development in eastern China, geothermal resources, is more for the water temperature below 100 low temperature geothermal, crustal movement is not very active, the earthquake caused a much lower risk even more." EXPLOITATION said.
Pumping settlement, how serious harm? While geothermal development may not be called a "seismic devil", if developed properly will also lead to a slow and serious geological disasters?? Land subsidence. Solid mining can be replaced, the oil and gas injection when required to ground, and ground water after being taken as hard as shallow groundwater through natural precipitation to add, so it will create gaps in the ground, gradually destroying the geological structure.
"The study found that all these years, Tianjin and North China land subsidence in some areas, the main reason may be the groundwater, geothermal water and oil and gas exploration." EXPLOITATION said. Some large-scale geothermal development in the northern city, already for many years because of drought and water shortage and excessive extraction of groundwater, and the exploitation of geothermal water is exacerbated by land subsidence, occurred in some areas increased the risk of subsidence. In recent years, Beijing, Tianjin annual rate of decline in geothermal water level permitted by the state have more than 1 meter, Xi'an even reached 5 meters.
