BEIJING - China's State Flood Control and Drought Relief Headquarters on Sept 15 activated a Level-IV emergency response in the northeastern province of Liaoning as Typhoon Muifa continues to move north after making its second landfall.

From the night of Sept 14 to the morning of Sept 15, Typhoon Muifa made successive landfalls in Zhejiang's Zhoushan city and Shanghai's Fengxian district.

According to the meteorological forecast, the typhoon will persist over land for a relatively long time. It is expected to pass through Jiangsu and Shandong, and then proceed north to the coastal areas of the country's eastern, northern and northeastern regions.

Local authorities have been advised to strengthen real-time monitoring and disaster prevention work, and urge people and boats to return to harbors or seek shelter.

China has a four-tier flood-control emergency response system, with Level I being the most severe response.
