Enola earthquake swarm

Last updated

The Enola earthquake swarm was a series of earthquakes in 2001 that centered on Central Arkansas. It follows the earthquake swarms of Arkansas in the 1980s, and predates the Guy-Greenbrier earthquake swarm that started in 2010. [1]

<span class="mw-page-title-main">Earthquake swarm</span> Series of localized seismic events within a short time period

In seismology, an earthquake swarm is a sequence of seismic events occurring in a local area within a relatively short period. The time span used to define a swarm varies, but may be days, months, or years. Such an energy release is different from the situation when a major earthquake is followed by a series of aftershocks: in earthquake swarms, no single earthquake in the sequence is obviously the main shock. In particular, a cluster of aftershocks occurring after a mainshock is not a swarm.

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).

The Reno earthquakes of 2008, also known as the "Mogul-Somersett earthquake sequence", occurred in or near the western Reno, Nevada, suburbs of Mogul and Somersett. The earthquake swarm began in February 2008, but the first significant quake of the series occurred on April 15, 2008, registering a 3.6 magnitude. On April 24, 2008, two quakes in the same area registered 4.1 and 4.2. On April 25, 2008, the quake of largest magnitude occurred, registering 4.7 on the Richter scale and causing damage in the immediate area around the epicenter, including destroying 200 feet (61 m) of a wooden flume supplying water from the Highland Ditch, also known as the Highland Ditch flume. The flume carried up to 50 million US gallons (190,000 m3) a day from the Highland Ditch to Reno's Chalk Bluff Water Treatment Facility and another 5 million US gallons (19,000 m3) to area irrigation users.

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.

California Township is one of 22 townships in Faulkner County, Arkansas, USA. As of the 2000 census, its unincorporated population was 1,467. The township experienced much unusual geologic activity with the Guy-Greenbrier earthquake swarm in 2010–2011.

The 2011 Oklahoma earthquake was a 5.7 magnitude intraplate earthquake which occurred near Prague, Oklahoma on November 5 at 10:53 p.m. CDT in the U.S. state of Oklahoma. The epicenter of the earthquake was in the vicinity of several active wastewater injection wells. According to the United States Geological Survey (USGS), it was the most powerful earthquake ever recorded in Oklahoma; this record was surpassed by the 2016 Oklahoma earthquake. The previous record was a 5.5 magnitude earthquake that struck near the town of El Reno in 1952. The quake's epicenter was approximately 44 miles (71 km) east-northeast of Oklahoma City, near the town of Sparks and was felt in the neighboring states of Texas, Arkansas, Kansas and Missouri and even as far away as Tennessee and Wisconsin. The quake followed several minor quakes earlier in the day, including a 4.7 magnitude foreshock. The quake had a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale in the area closest to the epicenter. Numerous aftershocks were detected after the main quake, with a few registering at 4.0 magnitude.
