Fears of a huge quake have risen in California after a series of 10 ‘mini quakes’ yesterday hit the San Andreas fault.
A string of 10 tremors struck Monterey County, a rural area in California, in what seismologists call a ‘swarm’ of earthquakes.
The largest of this swarm, a 4.6-magnitude quake, was felt in San Francisco more than 90 miles (145 km) away.
The structures were uncovered in the Harrat Khaybar region in Saudi Arabia in the 1920s and were referred to as the ‘Works of the Old Men’ by the region’s Bedouin population.
Most of them were discovered through satellite surveys and no archaeological fieldwork has yet been carried out.
Previous research has found thousands of stone structures that form geometric patterns in the Middle East.
American troops would find themselves badly outnumbered and at risk of defeat if war suddenly broke out with North Korea.
That is the stark warning issued by Lieutenant General Jan-Marc Jouas, the former deputy commander of U.S. Forces in Korea, in a letter to Democrats this month.
Jouas cautioned that it would take days or months for reinforcements to reach the region, leaving 28,000 American troops and 490,000 South Korean soldiers to fend off 1.2million North Korean fighters.
