Two Earthquakes in NJ

On April 5, 2024, the lab started as usual.  We were getting the equipment out to investigate the coefficient of static friction when quite a strange noise caught the students' attention...  We witnessed a Whitehouse Station earthquake (M 4.8) followed by a few aftershocks.  

In the afternoon, the Gladstone earthquake (M 3.8) shook NJ.

The map shows numerous earthquakes (M > 2.5) within the last 24 hours before the screenshot was taken.  Did you notice anything unusual about the blue dot that shows the location of the NJ earthquakes today?
