For those of you living in Korea, don't be alarmed if you experience a sudden power outage Thursday afternoon.
The Korean government will carry out a nationwide drill at 2 p.m. on Thursday, in preparation for possible power shortages.
The drill, which will last for about 20 minutes, will be conducted in two stages - first, rescuing people trapped in elevators and controlling traffic, and second, shutting off electricity at 28 buildings.
The government-run exercise comes amid fears of a possible blackout in July and August, when summer is in full swing.
Earlier this month, Korea's electricity reserves fell below the nation's threshold of four megawatts for the first time since the nationwide blackout last September.
