Gansu earthquake: Scientists in China believe they received an ominous signal days before

Researchers picked up warning signs on Friday – days before a 6.2 magnitude quake struck Gansu – but were unable to say exactly where it would strike.

Chinese researchers expected an earthquake to strike hours before the deadly 6.2 magnitude quake in the northwestern province of Gansu – but were unable to say where it would happen.

More than 120 people have died since the quake struck just before midnight on Monday, with the epicentre in a township located in the autonomous county of Jishishan.
