Sundar Pichai reveals Google’s next big project to make the world a safer place – Gadgets Now
Natural disasters like floods or earthquakes catch completely off guard and are available with none serious prior warning intrinsically. sometimes one often wonders, is it possible to detect earthquakes? Well, that’s exactly what Google and its CEO Sundar Pichai have asked an equivalent question and that they seem to possess a couple of answers also.
Is it possible to detect earthquakes with submarine cables? we expect it'd be.https://t.co/6oIZTxg1wk

Google recently conducted an experiment using its subsea fiber optic cables, which showed that it might be useful for earthquake and tsunami warning systems.
Valey Kamalov and Mattia Canton from Google Global Networking posted a blog detailing how Google plans to detect earthquakes. “Last October, a thought came to us: we could detect earthquakes supported spectral signatures—performing a spectral analysis of Stokes parameters to seem at frequencies that are typical of earthquakes,” they said within the blog post.
Google believes that its approach relies on technology that's widespread on today’s fiber-optic networks. many kilometers of fiber optic networks already span the world, operated by governments, telecommunications providers, and technology companies, including Google. “By collaborating with the worldwide subsea cable community, we could also be ready to improve the world’s ability to detect and research seismic activity around the world,” Google said within the blog post.
How Google can make it work: By using undersea cables
Google features a global network of undersea cables which makes it possible to share and search information “around the planet at the speed of sunshine .” “Fiber optic cables connect far-flung continents along the ocean bottom, and far of the internet’s international traffic travels over these cables,” Google explained within the blog post.
Google first started performing on this in 2013 but it had been only in 2019 that Google conducted its first experiment. Initially, there was no state of polarisation (SOP) changes that would detect an earthquake. “Then, on January 28, 2020, we detected a magnitude 7.7 earthquake off of Jamaica—1500 km faraway from the closest point of 1 of our cables!,” Google further said within the blog post. The state of polarisation continued to point out a sole for five minutes after the earthquake happened. This, as per Google, correlated to the time period of the seismic wave from Jamaica to the cable, and therefore the duration of the spike was about 10 minutes.
Since then Google has been ready to detect moderate-sized earthquakes in Mexico and Chile.
“We’re excited by the first success of detecting seismic events with subsea cables, which may improve our ability to watch both the Earth’s structure and earthquake dynamics,” noted the corporate within the blog post. However, this is often just the start, consistent with the tech giant. The blog post further noted, “to create a strong earthquake monitoring system, researchers need advanced mathematics and data analytics, where advanced computing systems like Google Cloud are often instrumental.”
