Precaution can help prevent land subsidence
A cleaning truck, an electric vehicle and their three occupants were swallowed by a sinkhole in the subway construction zone of Guangzhou, Guangdong province, on Sunday. To rescue the three missing people, who were identified on Wednesday, more than 1,100 rescuers and 192 emergency relief vehicles were pressed into the search operation.
The accident is a big tragedy for the missing people's families. But the urban authorities should do more to draw a lesson from this and prevent such tragedies from happening again.
Although the authorities are still investigating the cause of the collapse-and despite the unpredictable occurrence of sinkholes-relevant government departments need to take more precautionary measures to prevent such incidents.
