(American Canyon, CA) -- In California, nerves are being rattled again as the USGS is reporting at least four aftershocks within 90 minutes in the Napa-American Canyon area this morning. The first aftershock was a magnitude 3.9 just after 5:30 Pacific time this morning. That's the biggest aftershock since Sunday morning's 6.0 shaker. Three more aftershocks followed, with magnitudes of 2.7, 2.8 and 3.0. Meanwhile, wine country is still in recovery mode after Sunday's big early-morning quake which has already caused at least one-billion dollars in property damage.
