Experts have just discovered something mind-blowing or, at least, totally unexpected.
There seems to be a mix of two of the most feared disasters – hurricanes and earthquakes. Scientists are calling these stormquakes.
It’s been reported that the shaking of the seafloor during a hurricane is able to rumble like a magnitude 3.5 earthquake and this can even last for days.
The info has been revealed by a study in this week’s journal Geophysical Research Letters.
The quakes are really common, but they were not noticed before because these used to be considered seismic background noise.
Stormquakes are not dangerous
It’s been also revealed that a stormquake is stranger than something more dangerous that can hurt you.
As you can imagine, no one is standing on the seafloor during a hurricane, said Wenyuan Fan, a Florida State University seismologist who was the study’s lead author.
The combination of two frightening natural phenomena might bring to mind “Sharknado,” but stormquakes are real and not dangerous.
“This is the last thing you need to worry about,” Fan told The Associated Press.
How are stormquakes created?
Storms trigger massive waves in the sea, and these cause another type of wave according to what experts say. The secondary waves are interacting with the seafloor only in particular locations, and this causes the shaking.
This reportedly only happens in places in which there are a large continental shelf and shallow flat land.
PBS.org revealed that ocean-generated seismic waves show up on U.S. Geological Survey instruments, “but in our mission of looking for earthquakes these waves are considered background noise,” USGS seismologist Paul Earle said.
The official website also mentioned at one point that such a combination between a strong storm and an earthquake can bring scary memories in mind such as the movie Sharknado, but it’s not the case because the results are not dangerous as highlighted above.
