Aftershocks likely for another two years

Current aftershocks as recorded by the Alaska Earthquake Center.

ANCHORAGE (KTUU) - Aftershocks from the 7.1 earthquake on Nov. 30, 2018 are likely to continue for another two years, according to Natalia Ruppert, seismologist with the Alaska Earthquake Center. Ruppert says an updated estimate actually indicates that "it will take up to two and half years (from the time of the 7.1 quake) for the aftershock sequence to go back to background levels.”

“Right now, we are recording about a dozen aftershocks per day, but most of them are really small,” says Ruppert. She also says the rate of activity had definitely decreased and it will keep decreasing. “So there will be fewer and fewer aftershocks and fewer and fewer larger aftershocks,” but that aftershocks from the original quake “will continue for many more months.”
