Knowing when an earthquake is about to occur, even a few seconds before its starts, surely seems like a scenario from sci-fi movies. But thanks to the ShakeAlert software app, meaning US Geological Survey’s earthquake early-warning system, it has become a reality.
The Washington Post tells us about the incredible powers of ShakeAlert: once installed on your smartphone, it will alert you about 20 seconds before a significant jolt starts. It’s not much, but 20 seconds still represents enough time for you to go outside or grab onto a wall. You may still have your underwear on as you head over outdoors, but who cares if a 7-level magnitude earthquake occurs that could kill you?
Available for the West Coast of the US
For the moment, ShakeAlert seems to be available only on the West Coast of the US. The app will display a countdown from 20 seconds until the earthquake starts so that the user will know exactly how much time he has left to find shelter.
ShakeAlert is not a USGS-exclusive invention. State and university partners contributed as well. The software app even has its own dedicated website, and here’s an important part of the description found there:
Many partnerships to utilize ShakeAlert in authentic environments such as utilities, hospitals, transportation systems, and educational environments are active today and more are being developed. In 2022 and beyond, the USGS and its partners will continue to expand these applications in coordination with state agencies in Washington, Oregon, and California.
Around the world, half a million earthquakes occur every year. Most of them are barely noticeable. The jolts are generally almost impossible to predict. However, we can sure hope that a lot of software apps similar to ShakeAlert will appear soon and be available in other parts of the world except the US.
