Idaho Earthquake - Why Idaho Is Still Shaking

On March 31, a 6.5 magnitude earthquake rolled through Idaho's Sawtooth mountain range, northeast of Boise. It was the second largest earthquake to strike Idaho, according to the .

The area has experienced in the months following the quake, some registering as high as magnitude 4.8. The shaking has been so strong, in fact, that a popular beach along Stanley Lake in the Sawtooth National Recreation Area has sunk into the water. "The most probable cause for the 'disappearing' of the inlet delta is a combination of liquefaction and compaction of saturated sediments and some possible sliding and later spreading on the delta toward the deeper part of the lake," Claudio Berti, director and state geologist of the Idaho Geological Survey, said in a . The March 31 earthquake occurred 16 miles north of the Sawtooth Fault, a 40-mile stretch of fault line discovered nearly a decade ago. Geologists have largely believed the fault was inactive, but the latest round of quakes have reinvigorated interest in the region.Related StoriesGeologists are puzzling over exactly what caused an earthquake in the otherwise quiet region. Some researchers suspect the Sawtooth Fault is actually longer than expected. Others believe the fault is now taking advantage of openings in Earth's crust and is slowly pushing north. One theory suggests energy from the Sawtooth Fault could have jumped to a nearby unknown fault, spurring the recent series of earthquakes.For now, the race is on to collect more data about the region, so that geologists can paint a clearer picture of what's happening below surface. In addition to gathering seismic readings and analyzing soil samples, researchers will use to hunt for signs of movement in the area.In the aftermath of a major earthquake, it's common for a series of smaller earthquakes, called aftershocks, to occur. Aftershocks, which usually originate on the same fault line, can last for days, weeks, months and even years following the main shock. The larger the earthquake, the longer it'll take the fault to get all that shaking out of its system.This content is imported from Twitter.

Thanks guys for making it so easy to access seismic data! — UMN Seismology (@UMNseismology)In some cases, seismic energy along a fault line will build up over a long time. A in the journal Nature suggested earthquakes that occur far away from tectonic plate boundaries may be lingering aftershocks from temblors that happened centuries earlier. The pace at which two tectonic plates slide past each other could dictate how long aftershocks may last, with slower movement leading to longer last bursts of related seismic activity. Scientists are currently working on ways to use artificial intelligence to forecast where aftershocks may occur. A team of researchers used 131,000 reported earthquakes to train a neural network to accurately forecast aftershocks, according to published in Nature. Fear not: Even though Idaho is still rumbling, that doesn't mean Yellowstone is headed for an eruption.Read ThisIdaho lies along the northern edge of a geologically active region called the Basin and Range Province. This region, which spans eastern California to Utah and down into Sonora, Mexico, has been stretched taut over the past 20 million years, creating a series of wide valleys and vast mountain ranges. It's also chock full of old seismic faults—just like the one that sprang to life on March 31.This content is imported from Twitter.

Since then, there have been over 10,000 magnitude 6-or-higher earthquakes in the western U.S. While the temblors can occasionally spur rumblings at the national park's geysers—as a in Colorado did in 1959—they aren't likely cause a volcanic eruption.Advertisement - Continue Reading BelowAdvertisement - Continue Reading Below
