KAVIK RIVER CAMP, Alaska (AP) Alaska's North Slope was hit Sunday by the most powerful earthquake ever recorded in the region, the state's seismologist said. At 6:58 a.m. Sunday, the magnitude 6.4 earthquake struck an area 42 miles (67 kilometers) east of Kavik River Camp and 343 miles (551 kilometers) northeast of Fairbanks, the state's second-biggest city. The U.S. Geological Survey says the earthquake had a depth of about 6 miles (9.9 kilometers.)
State seismologist Mike West told the Anchorage Daily News that the earthquake was the biggest recorded in the North Slope by a substantial amount. "This is a very significant event that will take us some time to understand," he told the Daily News.

Shaking pipeline ?
more data - no info on that pipeline ‘cause’....but it will be MSM’s focus.
Isnt Kavik where Sue from Life Below Zero lives?
Just checked the USGS. Whole lotta shakin’ going on in that neck of the woods, scores of smaller quakes before and after. Anyone know if that’s SSDD or atypical?
Weather and natural events are fascinating. More so than the political pea soup.
We have no control over either one. God does.

God has control, but He made man so man can plan. :-)
I’d say atypical. USGS says around 200 2.5+ quakes in the last day for that area.

This probably automatically shuts down the pipeline. An inspection is likely in order. If a visual inspection finds nothing, they will probably run an intelligent pig through the pipeline.
I worked in the oil patch on the North Slope for 26 years. Earthquakes in that area are as rare as honest politicians. The whole area is permafrost from about 16” below the surface down to about 3000 feet, sometimes more. The oil in the region is typically 8-10,000 feet and comes out of the ground at 140-160*F so we know that its not frozen down there. Its probably The Russians.
Nah, the pipeline was built for this. It’s still pumping and they run pigs thru all the time!
"A cleaning "pig" for a 28-inch oil pipeline. The blue plastic disks seal against the inside of the pipe to propel the device and to remove loose sedimentation or scale buildup. The black rectangles at the top and the circular disks in the center are magnets to attract and remove any loose metal objects in the pipe." They can squeak and squeal when being rammed through the pipeline. (I had to look it up.) https://en.wikipedia.org/wiki/Pigging
I’m familiar with cleaning pigs. The intelligent pigs have things like eddy current sensors to detect any defects such as corrosion and cracking.
I have also seen pigs used in pipelines for product separation. One pipeline where I did some terminal work handled gasoline (several grades), butane, and propane. I installed the custody transfer measurement systems.
I had no idea what running a pig meant. I looked it up and replied to you so others might save a minute or two. I have always been fascinated by engineering of all kinds.
My son sometimes talks about going to work in Oil and Gas. Where does one start?
