Ten days after the supermoon passed close to earth a 6.0-magnitude earthquake has rocked parts of northern California, injuring dozens of people, damaging historic buildings and setting some homes on fire. The biggest quake in the region in 25 years jolted many residents out of bed when it hit at 3:20am (8:20pm AEST). The earthquake was centred about 10 kilometres south of the city of Napa. Three people were seriously injured, including a child who suffered multiple fractures after a fireplace fell on him, One local hospital said it had treated 89 patients following the earthquake.
Most damage on Sunday, appeared centred around Napa, a famous wine-producing region and a major tourist destination in northern California. It was the largest to hit the area since the Loma Prieta quake in 1989, which killed 63 people and caused $US6 billion in property damage. That quake measured 6.9, while the famous one that levelled San Francisco in 1906 measured 7.8.
