How to spot a big earthquake in your country

A massive earthquake is likely, according to the US Geological Survey (USGS).
The USGS said on Monday that it was investigating the magnitude 5.1 earthquake that hit northern China’s Hebei Province on Monday, killing at least eight people.
The quake, which was felt in several parts of the country, struck at a depth of nearly 200 kilometres (125 miles).
The USGS has previously reported that the biggest earthquake ever recorded in the world was recorded in South America’s Andes Mountains in 1879.
It’s estimated that there are about 6,000 smaller quakes in China, the world’s second largest economy.
