Two powerful earthquakes struck South Korea on Monday night, injuring at least 8 people.
South Korean meteorological agency officials warn that more powerful tremors of a magnitude 6 or higher may follow.
Two tremors with estimated magnitudes of 5.1 and 5.8 hit the city of Gyeongju in the south of the country within 50 minutes of each other.
Officials say the second quake was the strongest observed since records began in 1978.
Many families spent the night at elementary schools and other public facilities.
