Many people in Interior Alaska felt the M4.7 earthquake near Salcha tonight, July 22, 2021, at 8:20 pm AKDT (Figure 1). This earthquake occurred in the Salcha Seismic Zone, a well-known area of seismicity with no notable fault traces on the surface. This zone has produced many earthquakes, including a M7 on July 22, 1937, exactly 84 years ago, to the day (Figure 1). Tonight’s earthquake is quite close to the estimated location from 1937. The fact that they both occurred on the same day 84 years apart is a statistical quirk, there is no scientific meaning behind tonight’s event happening on the anniversary of the 1937 M7, but it is, nevertheless, interesting.
