The communities in coastal areas at risk of tsunamis should get proper information about evacuation and mitigation. The government and other authorities should provide information for them to take action. One of them is how does the tsunami warning system work.
This system is integrated with good infrastructure to run. There are many challenges to building legit infrastructure, but it is the country's duty to protect its people. Find out how this system works, so the authorities can prepare and work their best to face this kind of disaster.
How Does The Tsunami Warning System Work?
Earthquake and Triggers Detection
Triggering tsunamis can happen in many ways, such as earthquakes, volcanic, and severe storms in the sea. Most likely it happens because of earthquakes that most systems would focus on. When there is an underwater earthquake, the seismometers will work.
A strong shake may trigger a tsunami and be read by the seismometers. The sensor will deliver information to the integrated system in real-time. Tsunami potential can be read once the shake reaches a certain threshold on the system. Yet, it is not the only thing to consider.
The location and magnitude of the earthquake are also important factors. When it reaches 7.5 magnitude and there is a seabed fault, it may cause big waves that will arrive at the coastal area. Not all kinds of earthquakes will result in tsunami waves.
Checking Tsunami Buoys
How does the tsunami warning system work involving tsunami buoys? They are floating devices that can read the wave movement in the sea. The buoys have sensors to detect the changes in waves in the ocean. The sudden movement can be read as tsunami potential.
Besides floating sensors, the buoys are also on the seafloor. Usually, these buoys will detect the water height. Sudden small changes may cause big tsunami waves to the coastal area nearby. The buoys are monitored at the stations to confirm whether or not it is forming.
Modeling Data and Forecasting Disaster
Data from sensors will be used to model the prediction. It is very important for the system to work fast in this stage because a tsunami may come in a few minutes after the severe trigger. With a computerized system, the result includes arrival time, wave height, and areas.
Another result that the government can expect from the modeling is the simulation of tsunami waves. The speed and depth are very important to understand. After that, the authorities in this field should predict when and where the tsunami could hit and how the effect will be.
Spreading Information
After it is confirmed that a tsunami will hit a certain area, the system will work to deliver this information to the community in the coastal area. The fastest and the most efficient option is using an SMS broadcaster. It can deliver messages fast to people in a dense area timely.
Only the authorities can issue this warning to the communities. It can be a simple text that pops up on the phone screen. Usually, this information contains the request for evacuation as soon as possible to a higher place so the waves will not affect them.
Evacuation and Mitigation System
This system is also part of how does the tsunami warning system work. People who get the messages should evacuate themselves. It means the disaster will happen soon and is risky to ignore. The authorities should deliver clear information about evacuation plans.
The people should follow the guides and routes, as well as the signs during evacuation. The message tells people what to do for the next steps. This method can save many lives and decrease the economic impact of the tsunami. Beforehand, it needs good public education.
Earlier evacuation is required to save more lives. However, it also depends on the quality of the system. If the devices are not reliable enough to use, delays are inevitable. They do not have a chance to prepare and evacuate to a safe place. The damage and loss can be severe.
How does the tsunami warning system work could it save more lives? The system is integrated and works with many devices. Using an SMS broadcaster to share information and warnings for the communities is a great choice since it can spread messages timely in a specific area.
