As a big nation with different disaster risks, China emergency alert system is reliable and trusted for the people to take the next action to stay safe. The system informs people about some threats, incidents, and possible disasters so that they can evacuate as soon as possible.
This system covers nationwide without any exception. It works fast and efficiently because the sensors work together with the broadcaster to spread information about emergencies. How does it work and what are the key features of this system that other countries might copy?
Important Keys of China Emergency Alert System
Different Types of Alerts
The best thing about the alert system in China is it has different types of alerts. With the same devices and system, it works for other purposes. The main alert is delivering information about natural disasters. It includes natural hazards, tsunamis, earthquakes, floods, storms, wildfires, etc.
This system also works to deliver information about public health safety. Different outbreaks and crises happen in China from time to time. The government initiates this system to inform people about them, so people can prevent themselves from getting infected.
Alerts work to inform about safety and security issues in China as well. It is related to incidents, mass protests, and accidents that happen in China. If there is a weather warning, the system will inform people about it a few hours before so they can mitigate it before it happens in the future.
Delivery Channels
China emergency alert system has different channels to inform the people about recent emergency situations. Their priority and fastest channel is mobile alert. This system uses a broadcaster to send the messages. It pops up on people’s gadgets immediately to inform them of an emergency in China.
They also inform using public announcement systems that there can be sirens in many public places, such as factories, public buildings, parks, and transportation hubs. The rest are television, billboards, and social media to reach more people who may miss other types of channels during an emergency.
Technology in Alert System
The Chinese government uses an integrated and latest network that works faster than the previous system. With a strong infrastructure in China, they can manage 5G technology to cover their telecommunication system. This network allows China emergency alert system to work timely as per its purpose.
Besides the 5G network, they also use GPS in the system. It helps the system to know which areas are affected because of the emergency situation. Thus, the people in that specific area will be prioritized to get the information fast since they are in critical conditions.
Operation of System
From time to time, China does the tests of this system because it is important to check its effectiveness. The local authorities should issue some texts even though it is not about an emergency case. It can be a general announcement or public education about mitigation and evacuation.
The system also checks the coverage because some areas in China are urban and remote areas. It may be difficult to receive information through text on the phone. This is why the latest technology is required because of this limitation. In a dense area, it checks for delays in delivery.
The Challenges of Alert System in China
Public Awareness
It is still the main challenge since the system is available to use. People may react differently, including to ignore the emergency alerts. It is quite difficult to lead them to have good interpretations and understanding that emergency situations could harm their lives.
Social Factors
The trust of people in the government is low, especially in some areas. This is why people respond differently when they see emergency alerts on their devices. This is the biggest challenge that they may have, especially when they need instructions.
Accuracy of Information
Another challenge is accuracy. The sensors in the system can get triggered because of the event, but it does not always trigger an emergency situation. When people receive messages from time to time, they get overwhelmed and tend to ignore the important alerts.
The China emergency alert system itself includes an SMS broadcaster that will send messages about the emergency situation to the people. The recipients are the communities that might be affected because of it. This device is reliable because it can send to a large volume of users at the same time.
