Utah has experienced over 1,200 aftershocks following the magnitude 5.7 earthquake that rocked Magna on the morning of March 18.
This week, scientists from the University of Utah Seismograph Stations (UUSS) recorded two separate magnitude 4.2 aftershocks felt across the Wasatch Front — one on Tuesday evening and the other on Thursday morning. But, rest assured, this seismic activity is not unusual.
“The earthquakes this week are still part of the Magna sequence. A lot of you are wondering if this is normal. There is a wide range of what is considered normal and the Magna sequence is within that range,” the UUSS stated in a Twitter thread Thursday morning.
they have more than average. This feels abnormal to us because this is the first time in most of our lives that we’ve lived near an earthquake sequence like this. But for the earth, this is business as usual.

To help prepare Utahns for future seismic activity, the annual Great Utah ShakeOut is taking place Thursday at 10:15 a.m. and is the state’s largest earthquake drill.
Due to the COVID-19 pandemic, experts suggest that residents hold a remote videoconference drill with their community, faith-based group, or employer.
#Prepare: The official date will still be TODAY at 10:15 am, but because of #coronavirus, you can choose any date this year that works for you. Please practice social distancing for your ShakeOut drill. Get info from @UtahShakeOut on how you can prepare: https://t.co/yV9UqzFq62 pic.twitter.com/uaE8FGttog

Utahns can still register for Thursday’s drill or schedule another ShakeOut drill for any day of the year. Participating in a drill can enable residents to be more prepared for a future event.
