A major quake hit the US state of Idaho on Saturday, injuring more than a dozen people and causing extensive damage to homes and businesses, officials said.
The epicentre of the quake was about 1,200 kilometres (930 miles) east-southeast of Lake Tahoe in the Cascade Mountains, US Geological Survey (USGS) said in a statement.
The quake was centered near the town of Silverton in the state’s central Idaho.
A magnitude-6.7 earthquake struck a town in southern Idaho on Friday, killing a couple and injuring more people.
The US Geological Service (USGSS) has issued a magnitude-7.3 earthquake and an 8.1 aftershocks in Idaho.
The region is one of the most seismically active in the country.
The area has suffered several major quakes, including one magnitude-8.1 in the mid-1980s.
More than 40 people have been killed in US quakes in the past 20 years.
