Typhoons and floods raged through North Korea and affected at least 20,000 people in the country, according to a recent U.N. report published on Sept. 8. North Korea faced one of its worst monsoon seasons in years this summer, and was also hit by three major storms in just a two-week span.

Satellite imagery taken on Sept. 7 — around or just after the time Typhoon Haishen landed — shows at least 33 square kilometers (12.7 miles) of flooded land, the U.N.’s Operational Satellite Applications Programme (UNOSAT) stated. However, this estimate is based on analysis done on only 8,000 square kilometers (3,088 miles) of North Korea’s east coast.
