The United States Geological Survey continues to analyze Sunday's earthquake, and their estimates show a potential economic impact of more than a billion dollars.

The center's latest update includes an orange alert level for economic losses.

"Our estimates have kind of have bounced around between $100 million to $1 billion to actually a billion to $10 billion based on our shaking," Kristen Marano, a USGS geophysicist said. 

Marano says it's the group's best estimate of the direct losses to infrastructure.

"We kind of multiply the individual populations at each intensity level to figure out economic losses," she said. 

Officials in Napa say they have no idea on a cost estimate at this point, but they will sit down and crunch numbers at a later date.
