How safe are you? Did you know that scientists are saying the number of earthquakes could double this year?
We are still in January, and yet
we have seen THREE
major earthquakes clocking in over a magnitude of 7! When
the 7.9 occurred in Alaska on the 23rd of January, there was much
fear of it creating a tsunami in the west coast. Lucky for us, it only was a
few inches high, but it could have been a lot worse. This earthquake was bad
enough to affect Florida, which is on the other side of the country!
I can't help but ask myself, what if it was a higher
magnitude? Sure, a magnitude
8.0 or higher don’t occur often, but when they do, they can completely destroy
the area where they happen.
It is being estimated that the earthquake count will double
this year. Below
is a map of the earthquakes that occurred last year. As you can see, most of
the earthquakes were small ones in the middle of the ocean, that really aren’t felt.
However, there have been big ones. Last
year there was a devastating earthquake that occurred in Mexico. It was a magnitude
of 8.1, and killed over 90 people. They had a tsunami hit, and one of the waves
was reported being 5.8 feet.
With the possibilities of earthquakes doubling, that also
means there are greater odds of the higher magnitude earthquakes occurring. Below
is a map showing how far the intensity of the earthquake, that occurred Mexico,
spread. Keep in mind, this is only feeling the earthquake. Not the after affects
like the ones seen in Florida from the smaller earthquake in Alaska.
You may be asking yourself, why now? What is making the scientists
believe this? The
rotation of the earth has a lot of impact on earthquakes. There are devices
that are used to measure the motion deep inside the earth’s core. If the earth
spins faster or slower, by even a millisecond, then it can impact what we feel
on the surface. However, it takes about 5-6 years for this impact to make its
way up to the surface. An occurrence of this was measured back in 2011. At the
end of last year, we saw quite a few earthquakes, as well as with the beginning
of this year.
Projections of where these earthquakes will occur have been
done. Back in 2015 a World Risk Report came out as seen in the picture below.
This shows which places are at risk.
The equator can
be seen as a danger zone. The reasoning if this is that it is the widest point
of Earth. That means that it also rotates the fastest. When there is a slowing
of the rotation of the Earth, this is the point that is going to be impacted
the most.
Of course, what areas at risk should be taken with a grain of salt. There
was a 7.9 earthquake that occurred in Alaska, even though this map shows they
have a lower risk.
