Four events were M3 or greater, but most of the seismicity is below M2.

Map of earthquakes in the area

Seismicity has occurred throughout this area, occasionally as clusters, in the 1980s through the early 2000s. Though there are a lot of earthquakes in the area in a short period of time, this type of activity is not uncommon. Typically we record an M4 earthquake about once a year in Utah. While it is possible for a larger earthquake to occur in this sequence, the probability of a larger future earthquake is low.

Earthquakes like these, that are felt but not damaging, are a great reminder of the earthquake threat in the Wasatch Front. The Wasatch fault system has the potential for a much larger earthquake, so it is important to practice earthquake safety and prepare your home.
