World Scientists used the Richter Scale for or a number of years to measure earthquakes but now largely follow the “moment magnitude scale,” which United States Geological Survey says is a more accurate measure of size.
THE BIGGEST PROBLEM WITH EARTHQUAKE
There is no proper warning system for Earthquakes.
We only get vague warning like “an Earthquake .can occur in this area in the next 100 years or so”
A RECENT REPORT
The last big tremor in the Himalayas was the Nepal earthquake of 2015 with a moment magnitude (Mw) of 7.8, killing nearly 9,000 people and injuring 22,000.The quake flattened large parts of the capital Kathmandu.
The quake was strong enough to shift Kathmandu south by I .5m, wasn’t a big earthquake like the ones that measure over Mw8.
GOOGLE’S NEXT BIG PROJECT
American multinational technology company Google recently conducted an experiment using its subsea fiber optic communication cables, which showed that it could be useful for earthquake and tsunami warning systems.
Mattia Cantono and Valey Kamalov from Google Global Networking posted a blog detailing how Google plans to detect earthquakes globally.”in 2019 October, an idea came to us: we could detect globally earthquakes based on spectral signatures performing a spectral analysis of Stokes parameters to look at frequencies that are typical of earthquakes:’ .
SUBSEA FIBER OPTIC CABLES
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals worldwide across stretches of ocean and sea.
Millions of kilometers of fibre optic communication networks already span the globally, operated by countries government, telecommunications providers, and technology companies, including Google.”By collaborating with the worldwide subsea cable community, we may be able to improve the world’s ability to detect and research seismic activity around the world:’ Google Earthquake Detection System
