Android is converted into a network warning zemletryaseniya Dragoons
System operation will start in California, it will be integrated into the existing system earthquake warning ShakeAlert.
Google creates a global alert system for earthquakes based on Android and deploys the first part of the system. It uses the accelerometer in Android smartphones and will collect data from
each smartphone. After processing the data, the algorithm can detect an earthquake and warn people in the area of possible defeat.
The system is available thanks to the strengths of Google — 88% of smartphones in the world run on Android. This allows the IT giant to collect device data and after analyzing them to learn about
earthquake.
Google expands the system in several stages. In the first phase, Google will begin working with USGS and the California office of emergency services. The company will
send alerts earthquakes for Android users in California. These alerts are generated by the ShakeAlert system — it uses the data of traditional seismometers.
On the second and third stages Google will be collecting data from smartphones in a single district and determine going on at the moment, the earthquake or not. This system is much cheaper
the deployment of a costly network of seismographs and does not require expenditures on their operation.
Based on the collected data, Google will display localized results in Chrome. It is assumed that he felt the earthquake, people will glance at your phone to make sure is not happening
whether it is in this point in time.
Before you send an emergency alert, Google starts with a simple posting of information on earthquakes in the search results.
Once the system determines that the earthquake started, it will send warning.
This is especially important for regions that do not have seismographs.
The system will not identify users — it needs anonymous data about the location of the devices.
Phone on Android can become a “mini-website” because it has an accelerometer function which detects the rotation of the device. Android uses data from the accelerometer, to understand
shaking the phone.
Android smartphones are sensitive enough to detect the waves of an earthquake. They are able to detect both types of waves — P-waves and S-waves. So is every smartphone but for full
paintings need a lot of smartphones.
P-wave (primary wave) – the first and fastest wave of the earthquake epicenter. S-wave (secondary wave) is slow but more powerful. Google is able to detect both of these waves.
Often people don’t feel a P-wave, but the system detects it and gives the signal to prepare for the S-wave.
The timing of the deployment of the system in Russia is still unknown. Seismic active regions in the country are the North Caucasus, South Siberia and the far East. The intensity of the seismic shock here
reaches 8-10 points on 12-point MSK-64 scale.
