Hot Dry Rock Geothermal Energy
An enhanced geothermal system (EGS) generates geothermal electricity without the need for natural convection, convective hydrothermal resources. Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock permeability (earth sciences), permeability are sufficient to allow energy extraction. However, by far the most geothermal energy within reach of conventional techniques Hot dry rock geothermal energy, is in dry and impermeable rock. EGS technologies enhance and/or create geothermal resources in this hot dry rock (HDR) through a variety of stimulation methods, including 'hydraulic stimulation'. Overview When natural cracks and pores do not allow economic flow rates, the permeability (Earth sciences), permeability can be enhanced by pumping high-pressure cold water down an injection well into the rock. The injection increases the fluid pressure in the naturally fractured rock, triggering shear events that enhance the sys ...

Basin And Range Province
The Basin and Range Province is a vast physiographic region covering much of the inland Western United States and northwestern Mexico. It is defined by unique basin and range topography, characterized by abrupt changes in elevation, alternating between narrow faulted mountain chains and flat arid valleys or basins. The physiography of the province is the result of tectonic extension that began around 17 million years ago in the early Miocene epoch. The numerous ranges within the province in the United States are collectively referred to as the "Great Basin Ranges", although many are not actually in the Great Basin. Major ranges include the Snake Range, the Panamint Range, the White Mountains, and the Sandia Mountains. The highest point fully within the province is White Mountain Peak in California, while the lowest point is the Badwater Basin in Death Valley at . The province's climate is arid, with numerous ecoregions. Most North American deserts are located within it. The ...

Colorado Plateau
The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries. The Colorado Plateau is largely made up of high desert, with scattered areas of forests. In the south-west corner of the Colorado Plateau lies the Grand Canyon of the Colorado River. Much of the Plateau's landscape is related to the Grand Canyon in both appearance and geologic history. The nickname "Red Rock Country" suggests the brightly colored ...

USDOE
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served in the pos ...

Western Morning News
The ''Western Morning News'' is a daily regional newspaper founded in 1860, and covering the West Country including Devon, Cornwall, the Isles of Scilly and parts of Somerset and Dorset in the South West of England. Organisation The ''Western Morning News'' is published by South West Media Group (formerly known as Westcountry Publications), a division of Local World. Its main office is based in Plymouth and it has journalists based in newsdesks in Exeter, Truro, Penzance and Plymouth. It also has a London editor based in Westminster. Bill Martin is editor and Philip Bowern is print editor. History The ''Western Morning News'' was founded on 3 January 1860, by William Saunders and Edward Spender, father of Sir Wilfrid Spender. It has been published continuously since the first edition, including throughout the 1926 General Strike and the Plymouth Blitz. By 1920, the Devon newspaper market was getting cramped, with all papers running into financial difficulties. In the same ye ...

2017 Pohang Earthquake
The 2017 Pohang earthquake, measuring magnitude 5.4 on the moment magnitude scale, struck Heunghae, Pohang, North Gyeongsang Province, South Korea on November 15, 2017. It is tied with the 2016 Gyeongju earthquake as the country's strongest earthquake in modern history. Earthquake The earthquake, along with several aftershocks, caused significant infrastructure damage in the southern port city of Pohang. At least 82 people were injured in the earthquake, including 15 people who were hospitalized. About 1,124 people stayed in temporary shelters after they had to leave their homes.

Induced Seismicity In Basel
Induced seismicity in Basel led to suspension of its hot dry rock enhanced geothermal systems project. A seismic-hazard evaluation was then conducted, resulting in the cancellation of the project in December 2009. Basel, Switzerland sits atop a historically active fault and most of the city was destroyed in a magnitude 6.5 earthquake in 1356. But the Basel project, although it had established an operational approach for addressing induced earthquakes, had not performed a thorough seismic risk assessment before starting geothermal stimulation. Seismic events in Basel reached the trip point of Richter Magnitude 2.9 six days after the main stimulation was started on December 2, despite precautionary reduction of the injection rate earlier that same day upon reaching earlier "soft" thresholds. However, further tremors exceeding magnitude 3 were recorded on 6 January (measuring 3.1), 16 January 2007 (3.2), and 2 February 2007 (3.2). In all, between December 2006 and March 2007, the six ...

Cooper Basin
The Cooper Basin is a Permian-Triassic sedimentary geological basin in Australia. The basin is located mainly in the southwestern part of Queensland and extends into northeastern South Australia. It is named after the Cooper Creek which is an ephemeral river that runs into Lake Eyre. For most of its extent, it is overlain by the Eromanga Basin. It covers 130,000 km². The surface of the Cooper Basin is mostly desert, including parts of the Simpson Desert, the Channel Country and Sturt Stony Desert. Oil and gas exploration of the basin began in 1962. Energy resources Oil and natural gas The Cooper Basin has the most important on-shore petroleum and natural gas deposits in Australia. The oil and gas window is located 1,250 m below the surface and was originally discovered in the 1960s (although there are larger oil and gas deposits off-shore). The first commercial discovery of gas occurred in 1963. It includes Australia's largest onshore oil field, the Jackson oil field. This ...
