After East Coast's strongest earthquakes in 100 years hit New York and surrounding areas, seismologists warned that more aftershocks could continue up to a week, CBS News reported.
The United States Geological Survey (USGS) has issued alerts that the ground is not done shaking yet.
No significant damages or injuries were reported after 4.8 magnitude earthquake on Friday, however, more than a dozen aftershocks have been reported from or near the epicentre since then.
As of Saturday, the USGS has given a 60% probability of aftershock registering 3 magnitude or greater within the next week, Fox News reported.
The probability rises to 84% of a 3 magnitude or greater aftershock by stretching the timescale to over the next month.
Dax Soule, a seismologist and assistant professor at Queens College, said, "While aftershocks are a concern for the first 24, 36, 72-hour period out to about a week, the entire East Coast is a seismically active area."
