Android devices make up as much as 70% of the total market share worldwide. And because of this wider network and the new technology, it can emerge as a powerful earthquake early warning system. Recent research indicates that the Android network can aid in early earthquake warnings , even in remote parts of the world.
How Android’s larger network could help it become an effective earthquake warning system
According to research conducted by Alphabet , Google’s parent company, the Android Earthquake Alert (AEA) has been able to provide “life-saving” warnings in many places across the globe. The co-founder of the study, Richard Allen, who’s also a visiting faculty at Google, adds that “ Android devices make up for 70% smartphones worldwide, and this helps it in becoming a reliable earthquake warning mechanism.”
If we talk about the traditional earthquake mechanism, it uses a network of seismic sensors to detect vibrations and send earthquake warnings. While this mechanism is considerably more reliable and faster, it is hard to set up the system in remote places. Many parts of the world, including those that are prone to earthquakes, do not have this mechanism. And this is where the Android network comes into play .
Your Android device is also an early earthquake detector
Almost all modern smartphones come with the accelerometer sensor built in. Interestingly, this sensor has been able to detect the vibrations. And therefore, researchers have been trying to figure out the best use of it to detect earthquakes from the very start. Many developers even made a dedicated app for detecting earthquakes, but they weren’t very popular, primarily because of the regional availability and more issues.
After a long research and development, we saw the Android Earthquake Alert (AEA) being introduced. As per a test carried out between 2021 and 2024, the system was able to detect an average of 312 earthquakes each month. It was able to take note of the earthquakes with magnitudes as low as 1.9 and as high as 7.8.
To further check its reliability, Google carried out a survey between 5 February 2023 and 30 April 2024, in which 1,555,006 users participated. Per the response, 85% of the users were able to experience the shaking, 36% of the users received the warning before the ground started shaking, and 28% users got the warning during the earthquake. About 23% of the users received the warning a few seconds after the shaking started.
It’s very interesting to see how our smartphones are able to detect earthquakes and save lives. This is a positive sign of how far the technology has come.
