'Ghost' That Haunts South Carolina Rail Line May Be Caused By Tiny Earthquakes
Wednesday January 29, 2025. 02:30 AM , from Slashdot
Sparks from steel rail tracks could ignite radon or other gases released from the ground by seismic shaking, Hough explains in an interview with Science. In Summerville, I think it's the railroad tracks that matter. I've crawled around tracks during my fieldwork in South Carolina. Historically, when [rail companies] replaced tracks, they didn't always haul the old track away. So, you've got heaps of steel out there. Sparks might be part of the story. And maybe the railroads are important for another reason. They may naturally follow fault lines that have carved corridors through the landscape. The findings have been published in the journal Seismological Research Letters. Hough also cites a paper published by Japanese scientist Yuji Enomoto that connects earthquake lights to the release of gases like radon or methane. Read more of this story at Slashdot.
