New plan to detect earthquakes early by Sundar Pichai

In previous days, India is witnessing a significant problem of the earthquake. Everyone has a question in their mind, how to detect the earthquake early? After so many issues, Google came up with the answer to this question. Sundar Pichai, the CEO of Google and Alphabet, tweeted that the company is coming with a new experiment of detecting the earthquake. Google is using subsea fiber optic cables for this experiment. The cable is capable of detecting earthquake and tsunami early and can be used as a warning system.

According to the experiments, optical fiber is used for sensing the earthquake activity within a radius of 100km. This technique would work over tens and thousands of kilometers. The fiber cable can also detect disturbances on the seafloor. Also, the company has posted in a blog that “Better yet, our technique relies on equipment that is present on the vast majority of the world’s existing fiber optic systems, so it is broadly applicable.” The company also told me that the cable can connect far-flung continents from the ocean floor. Most of the international traffic travel over these cables. Google also added, “Google’s global network of undersea cables makes it possible to share, search, send, and receive information around the world at the speed of light.”

The cable used is made up of optical fiber. The data carried in the wire in the form of pulsing light with the speed of 204,190 kilometers per second. As the cable is capable of traveling data at such high speed, it can encounter a minimal distortion. The company has thoroughly explained the SOP, “The SOP changes in response to mechanical disturbances along the cable and tracking these disturbances enables us to detect seismic activity,”

Google started this project in 2013, and the first experiment took place in 2019. The technique was able to detect a moderate earthquake of Mexico and Chile. India is also likely to use this technique for detecting mild earthquakes for about three-four months.
