The Core Principles about Earthquake Alarm

Earthquakes may invite worse disasters following, such as another wave and tsunami. This is why local authorities should understand better about earthquake alarm because the warning could save people who live in the potentially affected area. It is also part of the duties to protect lives in the country.

For the countries who are in the Ring of Fire, it is important to prepare mitigations. Earthquakes in these areas happened almost every day with different magnitudes. With an alarm, people can evacuate when it happens. Here are some core principles of alarm to inform about earthquakes.

The Principles about Earthquake Alarm

Detecting Waves

The wave of an earthquake usually consists of two parts, the primary and secondary. The primary wave is the first wave that arrives. Some people may not feel it if the magnitude is low. Thus, the damage because of this wave is usually low. It can be detected by sensors in the system.

The second wave is usually slower, but it can barely happen. However, its destructive level is higher compared to the primary wave. The system usually predicts the second wave only according to the primary wave. During this critical time, a warning is issued to inform people.

Monitoring The Earthquake

Before an alarm is issued, the system monitors the earthquake in real-time. The ground motion can change until the next few minutes. So, it is important for the system to see the possibility of another earthquake. The destructive earthquake can trigger a tsunami and damage on the land.

While monitoring, the sensors in the system continuously communicate. Since the system about earthquake alarm is centralized, all data is recorded on the central server. After that, it can determine earthquake alarms to tell people to do the next action to save themselves.

Analyzing and Predicting

After the sensors record that there is seismic activity, the system immediately works to analyze data. There are many factors to estimate, such as the magnitude of the earthquake, the epicenter of the earthquake, intensity felt in different areas, and estimated secondary earthquake.

This prediction can help people to understand that their lives are threatened or not because of this disaster. The messages that pop up on their screen could inform them that the earthquake may happen again and tell them to do other actions regarding their safety.

Earthquake Alarm Issued

This is a critical stage because the alarm should arrive timely on everyone’s gadget. This is because the time to prepare everything is limited before another wave and potential tsunami if the magnitude is high. So, the system should rely on the latest devices to ensure it works efficiently.

Besides sending to cell phones, this alarm can be connected to other devices where people pay attention to wherever they are. Some alerts are on TV, radio, and public announcements. The most efficient one is still a pop-up message on the cellphone because most people have it.

The Function of Earthquake Alarm

Gaining Public Attention

Some people may not realize that an earthquake comes because of low intensity. However, the secondary wave could be dangerous. With an earthquake alarm issued, people can have better awareness. The text is usually informing about magnitude, location, and intensity in different areas.

Telling People to Take Actions

People in different areas should take different actions. For example about earthquake alarm, those who are in the car or vehicles should stop for a while because another hit can lead to an accident. Meanwhile those people who are in the building should go outside and go to a safer place.

In industrial settings, the machines should stop working because it can lead to dangerous and harmful cases such as fire. Some utilities also had better shut down because it could trigger another disaster that may not be related to the earthquake itself. The warning could help people to take action fast.

Following The Guidelines

With a timely alarm, people can follow the guidelines on the text. It helps people to do many things as preparation and mitigation. They can go to evacuation areas or higher areas in case the earthquake triggers a high wave like a tsunami that threatens many losses.

Sending messages to everyone about earthquake alarm can be more reliable by using an SMS  broadcaster. This is a device to send messages to a large volume of users at the same time. It can be integrated with the Internet of Things which is useful to be part of a disaster warning system.
