The Emergency Management Bureau of Shenzhen is accelerating the construction of a modern emergency monitoring and early warning command system in the city.  
The system currently being built was already put to use during an afternoon rainstorm, Aug. 18, when an early warning station the Luohu Emergency Management Bureau installed on a northern slope of the Xiantong Sports Park in Liantang issued red alerts signaling potential landslides.
After receiving the early-warning signals, the bureau promptly alerted relevant district personnel in vulnerable areas of the risk.
At that point, staff from the Liantang sub-district office rushed to the Xiantong Sports Park and worked with the employees in the park to evacuate visitors and close the area down.
According to the Luohu Emergency Management Bureau, the district has installed automatic monitoring and early-warning systems on the slopes of 29 sites.
Likewise, Shenzhen is expanding the system to cover more low-lying sites as well, such as the subway stations, which are vulnerable to flooding during heavy rains. So far, the city has established 202 monitoring stations.
To bolster efforts, the metrological department is making increasingly accurate weather forecasts and warnings for extreme weather conditions, earning valuable time for the city to prepare for emergencies.
Apart from calling 12350 to report geological disasters like surface collapse and landslides, residents can also use a WeChat platform to alert emergency management departments to other potential public security and safety hazards.
