An aftershock at 6.4 magnitude on Sunday has killed six & injured nearly one thousand. Four people were confirmed dead & 20 others were seriously injured in Shaanxi Province. The aftershock at 6.4 magnitude on Richter scale gave rise to serious fears of quake-created lakes bursting and causing serious floods.

Sunday’s aftershock destroyed 71,000 houses. The scale of damage to property indicates that the number of casualties might go up sharply once detailed information is available. Meanwhile the water resources ministry said in a statement that 69 dams scarred by the force of China’s most powerful earthquake in three decades were in danger of bursting.

The aftershock struck at 4.21 p.m. in the Qingchuan county, but tremors were felt all over Sichuan & large parts of neighbouring Gansu & Shaanxi provinces. The tremors caused a cave-in on a provincial highway & disrupted traffic in Lueyang county of Sichuan, Chen Weiming, publicity official at the local government said.
