The day after a 2.3 magnitude earthquake rattled residents of eastern Connecticut, another very small earthquake was detected, according to officials from Weston Observatory at Boston College.
On Thursday morning, several residents called police to report loud booms, followed by shaking.
Then around 10:30 a.m. on Friday, police received two more calls reporting something similar.
After hearing of those reports, a reporter called Weston Observatory and officials there saw a smaller seismic wave and measured a 0.4 earthquake around 10:26 a.m.
An expert at the observatory said because it was so small and shallow that people would have been more likely to hear the quake, than feel any shaking.
