The China Earthquake Administration has activated level-I emergency response procedures following a 7.0-magnitude earthquake Tuesday in Jiuzhaigou County in southwest China's Sichuan Province.

Work teams have been sent to the stricken area to carry out emergency operations, the administration said in a statement.

China has a four-level earthquake emergency response system, with level-I being the top.

The Red Cross Society of China has also launched its emergency response procedures, sending 1,000 first aid kits, 2,000 quilts and 200 tents to the area.

The Chinese Red Cross Foundation has sent work teams to verify the casualties and damage, and has allocated 100,000 yuan (over 14,914 U.S. dollars) for emergency aid.

At least five people have been killed and over 60 others injured in the quake, including 30 in serious condition.
