A new map released by the U.S. Geological Survey reveals that nearly half of Americans should be prepared for a potentially damaging earthquake.

About 148 million Americans live in an at-risk area, nearly double the number of people believed to be in earthquake zones a decade ago.

USGS Seismologist Lucy Jones said this afternoon on “Happening Now” that people who live east of the Rocky Mountains tend to think that earthquakes are just a West Coast problem. She said that all Americans should know how to prepare for a quake.

“They don’t have to kill you, and they don’t have to even really bankrupt you if you take precautions,” she said.

Jones said that it’s important to be informed about quakes.

“Don’t think it’s somebody else’s problem,” she said. “It could happen to you.”
