Buckle up for likely earthquake aftershocks, geologists say. Here's how the East Coast should prepare.

• Geologists say the East Coast could be in for more earthquakes in the weeks ahead.
• There's also a slim chance of aftershocks with a similar or larger magnitude, the USGS said.
• To prepare, you should create an emergency plan, secure household items, and assemble a bugout bag.

Aftershocks could hit the East Coast following Friday's 4.8 magnitude earthquake, and millions of people in the region should prepare in the unlikely event the earthquake is bigger next time, the US Geological Survey said.
