Seattle's 'Swift Quake' surpasses 2011 'Beast Quake' seismic activity

Western Washington University geology professor Jackie Caplan-Auerbach said she’s part of a Pacific Northwest earthquake Facebook group and saw someone ask how the seismic activity from the two events compared. 

“Somebody posted and said 'Well, did the Taylor Swift concert make a Beast Quake?' And I was like 'Oh I am on that, that’s fun',” she said. 

She got to work, pulling the data from the two nights of concerts.
