Oklahoma Suffers Its 2,724th Earthquake Since 2010

A cluster of earthquakes in Oklahoma earlier this month helped push the state to 62 temblors this year alone of magnitude 3.0 or more — and 2,724 of that magnitude or more since 2010.

This year is on track for a huge decline from the peak of Oklahoma’s restlessness in 2015, when the state felt a staggering 903 quakes of magnitude 3 or greater. But it’s also a far cry from Oklahoma’s norm before 2009, when the state recorded an average of one or two magnitude 3.0 or more earthquakes each year.

The rapid rise in quakes and subsequent fall bolsters the findings that Oklahoma’s foundations are moving because of oil and gas activities. Most quakes are due to the injection of large amounts of wastewater from wells into subterranean rock layers. A few localized quakes are likely the direct result of fracking, in which underground charges are set off to puncture rock and improve the flow of oil and gas into a well. As Oklahoma regulators have finally limited the amount of wastewater that oil and gas operators can inject underground, quakes have fallen off.

7 Years After Fukushima Disaster

It’s been seven years since a magnitude-8.9 earthquake in northeastern Japan triggered a massive tsunami that led to a meltdown at the Fukushima Daiichi Nuclear Power Plant. Seven years since radioactive materials from the plant poured into the air and the ocean and began making its way toward the West Coast of the United States.

Now that seven years have passed, how radioactive are the waters around the U.S.-Canadian West Coast? And how radioactive is the air and soil on the mainland?

The U.S. and Canadian coastal waters in the Pacific are contaminated, analyses show, but radiation levels are still well below federal standards set by the Environmental Protection Agency, said Ken Buesseler, a senior scientist at the Woods Hole Oceanographic Institution in Woods Hole, Massachusetts. []

The levels are so low, that swimming eight hours every day for a year would only increase a person’s annual dose of radiation to an amount that is 1,000 times less than a single dental X-ray, Buesseler said.

6.6 earthquake hits New Guinea, Papua New Guinea.

At least 18 people were killed by a magnitude 6.6 quake that struck Papua New Guinea’s mountainous Southern Highlands early Wednesday, an official said, adding to the death toll from a larger quake last week. It was the most severe of a series of aftershocks that have rattled the resource-rich region, about 600 km northwest of the capital Port Moresby, complicating efforts to provide aid to nearly 150,000 people in need of emergency supplies.

Yellowstone Swarm

A swarm of more than 200 earthquakes struck Yellowstone National Park over the past two weeks. The 200 temblors began on Feb. 8 and ramped up on Feb. 15 in an area about 8 miles (13 kilometers) northeast of West Yellowstone, Montana, according to the U.S. Geological Survey (USGS). In reality, many more tiny quakes hit the region but were simply too small for seismometers to pick them up, according to the USGS.

These swarms occur when stress levels shift along smaller faults in an earthquake region, according to the USGS. Swarms typically have two ultimate causes: shifting at major tectonic plates; or movements of water, gas or magma under the surface.
