Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes ...

Central Arkansas
Central Arkansas, also known as the Little Rock metro, designated by the United States Office of Management and Budget as the Little Rock-North Little Rock-Conway Metropolitan Statistical Area, is the most populous metro area in the U.S. state of Arkansas. With an estimated 2020 population of 748,031, it is the most populated area in Arkansas. Located at the convergence of Arkansas's other geographic regions, the region's central location make Central Arkansas an important population, economic, education, and political center in Arkansas and the South. Little Rock is the state's capital and largest city, and the city is also home to two Fortune 500 companies, Arkansas Children's Hospital, and University of Arkansas for Medical Sciences (UAMS). History The site known as "little rock" along the Arkansas River was found by explorer Bernard de la Harpe in 1722. The territorial capitol had been located at Arkansas Post in Southeast Arkansas since 1819, but the site had proven unsu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guy-Greenbrier Earthquake Swarm
The Guy-Greenbrier earthquake swarm occurred in central Arkansas beginning in August 2010. The epicenters of earthquakes in the swarm showed a linear distribution, with a clear overall shift in activity towards the southwest with time, and the largest event in the swarm was the 2011 Arkansas earthquake, at 4.7 on the moment magnitude scale. Cause It has been suggested that the swarm was triggered by drilling activities associated with the exploration and production of shale gas in the Fayetteville Shale in northern Arkansas. Analysis of the swarm has found no link between this relatively shallow drilling and the earthquakes, but has instead suggested a link with deep waste disposal drilling similar to that identified at the Rocky Mountain Arsenal in the 1960s, and has led to a moratorium on such drilling being proposed covering an area of .
