Listen to the Podcast:
We know we can’t prevent earthquakes from happening, but Google turned on “Android Earthquake Alerts” so that people can take better action when a strong earthquake strikes and save more lives.
Google Earthquake Alert for Android phones is a free service that can save lives, but you may need to activate it directly in some situations.
People often do not listen to the loudspeakers that warn of earthquakes because they do not work or they do not have them in their town. Likewise, in a world where it’s hard to get away from your cell phone, the warning on your phone might be a better way to let you know about earthquakes.
How does the earthquake warning system work?
It is a free service for Android phones that can find earthquakes around the world and warn users before they start. Google is working with the ShakeAlert team to send alerts from their system. His system uses a network of 1,675 seismic monitors to record tremors and then analyzes the data to determine where and how strong they are.
The ShakeAlert system then sends a signal to the earthquake alert system, which notifies people directly. The accelerometers inside all cell phones allow them to detect movement and speed. If your phone detects a change in the Earth’s magnetic field that could be an earthquake, it will send a signal to the computer that finds earthquakes, along with an approximate location.
How to activate the Google seismic alert?
Android phones can be configured to send earthquake alerts in the following ways:
- Open the “Settings” menu of your cell phone.
- Scroll down or find the option that says “Security and Emergency.”
- Turn on the part called “Earthquake Alert”.
- Done, your phone will receive the alerts.
This menu also has a part called “Alert Sound” or “Alert Reminder” where you can choose whether you want the alarm to sound only once or every 2 to 15 minutes. You can also turn off the sound, which is pointless for an alarm.
What kind of earthquakes does Google Earthquake Alert protect against?
Google Alerts will inform you about two types of earthquakes: those that are not too strong and those that are very strong.
danger alert: This is meant to inform you of light tremors and give you more information when you tap the alert. Users who feel tremors between 3 and 4 on the MMI scale during an earthquake with a magnitude of 4.5 or greater will receive this message. Pay attention to the volume and “do not disturb” options.
Action Alert: This is to get your attention before you start to feel mild to strong shaking, so you can take steps to protect yourself. Users who feel shaking of 5 or more on the MMI scale during an earthquake of magnitude 4.5 or more will receive this message.
Sasmex Alert without Internet Connection
In 2023, the Seismic Alert System of Mexico, also known as Sasmex, will be accessible on mobile devices. This year, the Seismic Alert System of Mexico will activate earthquake alerts on cell phones in Mexico City. The goal is to allow the population to take precautions against an imminent earthquake regardless of whether they have an internet connection or mobile data, since, according to Sasmex, the system works with special technology and not with a traditional internet application.
