Oklahoma's earthquake threat now equals California's due to man-made temblors, USGS says

[Old Rocks]

The seismic risk is forecast to be so high that the chance of damage in Oklahoma and southern Kansas is expected to be similar to that of earthquakes in California, USGS scientists writing in the journal Seismological Research Letters said Wednesday.


In 2016 alone, Oklahoma experienced several damaging earthquakes, including a magnitude 5.0 temblor in November near the central oil town of Cushing — which proclaims itself the “Pipeline Crossroads of the World” — that dislodged unreinforced bricks in chimneys and storefronts, sending them tumbling onto the sidewalks.

OK now has the same quake risk but no ocean, mountains, deserts, redwood forests, or beaches

FRACK BABY FRACK!

Your stupid.

Since what he posted is accurate, and he backed it up with links, why would you say that. Except maybe, for the fact that you are stupid.

1812 Earthquake in Arkansas caused the Mississippi River to run backwards

On this day in 1812, the most violent of a series of earthquakes near Missouri causes a so-called fluvial tsunami in the Mississippi River, actually making the river run backward for several hours. The series of tremors, which took place between December 1811 and March 1812, were the most powerful in the history of the United States.

The unusual seismic activity began at about 2 a.m. on December 16, 1811, when a strong tremor rocked the New Madrid region. The city of New Madrid, located near the Mississippi River in present-day Arkansas, had about 1,000 residents at the time, mostly farmers, hunters and fur trappers. At 7:15 a.m., an even more powerful quake erupted, now estimated to have had a magnitude of 8.6. This tremor literally knocked people off their feet and many people experienced nausea from the extensive rolling of the earth. Given that the area was sparsely populated and there weren’t many multi-story structures, the death toll was relatively low. However, the quake did cause landslides that destroyed several communities, including Little Prairie, Missouri.

The earthquake also caused fissures–some as much as several hundred feet long–to open on the earth’s surface. Large trees were snapped in two. Sulfur leaked out from underground pockets and river banks vanished, flooding thousands of acres of forests. On January 23, 1812, an estimated 8.4-magnitude quake struck in nearly the same location, causing disastrous effects. Reportedly, the president’s wife, Dolley Madison, was awoken by the tremor in Washington, D.C. Fortunately, the death toll was smaller, as most of the survivors of the first earthquake were now living in tents, in which they could not be crushed.

The strongest of the tremors followed on February 7. This one was estimated at an amazing 8.8-magnitude and was probably one of the strongest quakes in human history. Church bells rang in Boston, thousands of miles away, from the shaking. Brick walls were toppled in Cincinnati. In the Mississippi River, water turned brown and whirlpools developed suddenly from the depressions created in the riverbed. Waterfalls were created in an instant; in one report, 30 boats were helplessly thrown over falls, killing the people on board. Many of the small islands in the middle of the river, often used as bases by river pirates, permanently disappeared. Large lakes, such as Reelfoot Lake in Tennessee and Big Lake at the Arkansas-Missouri border, were created by the earthquake as river water poured into new depressions.

Geography in the News: New Madrid Earthquake

The New Madrid is one state away from Oklahoma. The vast increase in quakes in Oklahoma is directly caused by the injection of drilling fluids.

Still just a theory .....

Sunni, have you the faintest idea of what theory means in science?

Denver earthquakes 40 years ago were caused by Uncle Sam, not Mother Nature

Here's the history of the Arsenal quakes from the USGS site:

In 1961, a 12,000-foot well was drilled at the Rocky Mountain Arsenal, northeast of Denver, for disposing of waste fluids from Arsenal operations. Injection was commenced March 1962, and an unusual series of earthquakes erupted in the area shortly after.

It was 32 minutes after 4 a.m. on April 24 when the first shock of the Denver series was recorded at the Cecil H. Green Geophysical Observatory at Bergen Park, Colorado. Rated magnitude 1.5, it was not strong enough to be felt by area residents. By the end of December 1962, 190 earthquakes had occurred. Several were felt, but none caused damage until the window breaker that surprised Dupont and Irondale on the night of December 4. The shock shuffled furniture around in homes, and left electrical wall outlets hanging by their wires at Irondale.

Over 1,300 earthquakes were recorded at Bergen Park between January 1963 and August 9, 1967. Three shocks in 1965 -- February 16, September 29, and November 20 -- caused intensity VI damage in Commerce City and environs.

The Denver series was forgotten, however temporarily, in October 1966, when a southeast Colorado tremor rocked a 15,000 square-mile area of that State and bordering New Mexico. Minor damage, in the form of broken windows and dishes and cracked walls and plaster, occurred at Aguilar, Segundo, Trinchera, and Trinidad.

Another strong shock rumbled through the Denver area on November 14, 1966, causing some damage at Commerce City and Eastlake. Slighter rumblings (below magnitude 3.0) occurred throughout the remainder of 1966, and through the first week of April 1967.

Then, on April 10, the largest since the series began in 1962 occurred; 118 windowpanes were broken in buildings at the Rocky Mountain Arsenal, a crack in an asphalt parking lot was noted in the Derby area, and schools were dismissed in Boulder, where walls sustained cracks. Legislators quickly moved from beneath chandeliers in the Denver Capitol Building, fearing they might fall. The Colorado School of Mines rated this shock magnitude 5.0.

Boulder sustained minor damage to walls and acoustical tile ceilings on April 27, 1967, as result of a magnitude 4.4 earthquake. Then a year and half after the Rocky Mountain Arsenal waste dumping practice stopped, the strongest and most widely felt shock in Denver's history struck that area on August 9, 1967, at 6:25 in the morning. The magnitude 5.3 tremor caused the most serious damage at Northglenn, where concrete pillar supports to a church roof were weakened, and 20 windows were broken. An acoustical ceiling and light fixtures fell at one school. Many homeowners reported wall, ceiling, floor, patio, sidewalk, and foundation cracks. Several reported basement floors separated from walls. Extremely loud, explosivelike earth noises were heard. Damage on a lesser scale occurred throughout the area.

During November 1967, the Denver region was shaken by five moderate earthquakes. Two early morning shocks occurred November 14. They awakened many residents, but were not widely felt. A similar shock, magnitude 4.1, centered in the Denver area November 15. Residents were generally shaken, but no damage was sustained. A local shock awakened a few persons in Commerce City November 25. Houses creaked and objects rattled during this magnitude 2.1 earthquake.

The second largest earthquake in the Denver series occurred on November 26, 1967. The magnitude 5.2 event caused widespread minor damage in the suburban areas of northeast Denver. Many residents reported it was the strongest earthquake they had ever experienced. It was felt at Laramie, Wyoming, to the northwest, east to Goodland, Kansas, and south to Pueblo, Colorado. At Commerce City merchandise fell in several supermarkets and walls cracked in larger buildings. Several persons scurried into the streets when buildings started shaking back and forth.

During 1968, ten slight shocks were felt in Colorado. Only one, on July 15, caused minor damage at Commerce City. In September of that year, the Army began removing fluid from the Arsenal well at a very slow rate, in hope that earthquake activity would lessen. The program consisted of four tests between September 3 and October 26. Many slight shocks occurred near the well during this period.

So the relationship between injection and quakes has been known for over 60 years.

The threat of the "Big one" cannot possibly be equal or close to California though.
