Utah’s mini-wave of minor earthquakes doesn’t portend that the big one is coming our way anytime soon — but it doesn’t lessen the chances either, according to James C. Pechmann at the University of Utah Seismograph Stations.
“I don’t think they’re related,” he said of quakes centered near Bluffdale in southern Salt Lake County and near Kanosh in Millard County. “They’re too far away from each other. And they’re not big enough to cause what we call remote triggering.”
On Friday morning, two earthquakes — one a 3.2 magnitude, the other 3.7 — centered south of Bluffdale shook southern Salt Lake and northern Utah counties.
