Good morning, everyone.
Thank you for joining me.
I hope everyone has a wonderful weekend.
Today is February 5, 2022.
Yesterday afternoon at 4:14, a local time there in
Lake Erie, not far from Cleveland, there was a
magnitude 4.2 earthquake, the 7th earthquake of this year.
Ohio normally only gets about one earthquake a
year, but of late that's been changed. Evidently,
according to USGS, these are all aftershocks of an
earthquake of a magnitude 4.0 that occurred in 2019.
Why don't they just say it was aftershocks
from the 2011 earthquake, which was a 4.2?
According to geologists, about every ten years
there in Ohio, there will be an
earthquake of a magnitude 4.0 or greater.
Past earthquakes were on February 1, a magnitude 1.6, January
29, a 2.0, on January 27, a magnitude 2.7, and a
2.5, January 5, a 1.9, and January 4 Magnet 2.8.
There is no tectonic place in this area to be
causing earthquakes, but there is ancient fault lines because at
one time this area was going to divide up in
half, rip apart and allow the oceans to come in
and create two actual separate bodies of land.
That would be the Mid-continent rift system.
Probably hard to see right here.
I got so many data put on the map, but it's the
red line here, or part of it is the red line.
It is the largest failed rift system ever discovered.
On Physics.org, they got the original traditional
Midcontinent rift system, but then using
ground penetrating radar, it was revised.
And you can see now here it's more
extended than what it was originally thought.
Here we got the Greenville fault, and now
they question about where they think that goes
compared to where it was before.
All right, here's Lake Erie, Lake Superior.
And originally they thought the Greenville Front fault line
was what caused the rift to stop rifting.
And now they disagree about that.
I keep saying how there is so
little that's known about volcanism and earthquakes.
Well, Ohio do not have
any earthquake monitors until 1999.
There are 21 monitors now in the state, and
they plan to put in more sometime this summer.
You may have noticed here in 1986 there
was a magnitude 5.0, 1944 over here, 2001.
Supposedly they have a 4.0 or
greater earthquake about every ten years.
And it used to be only one earthquake that was
felt by people, only one a year used to be.
And this is the 7th earthquake
they've had so far this year.
Eleven people said they felt this earthquake
that occurred yesterday at 04:14 P.m.
local time.
Can you imagine the damage that would happen, the
injuries and death, if there was an earthquake there
in Cleveland with all the unreinforced older buildings, they
gave an intensity level of three here, which means
it was felt quite noticeably by those eleven people
indoors, especially if they were on the upper floors
of a building.
But most people probably didn't even
recognize it was an earthquake.
May have thought it was just
the vibration of a passing truck.
Might have been strong enough for people to
realize what direction the earthquake came from.
This is one of the farthest
earthquakes out in the Lake.
See that the 2.4 USGS does
not have a moment tensor ball.
But if you look at the earthquakes, yes, there's
probably a fault throughout here and I've talked about
these ancient fault lines that are being reactivated.
And in Ohio, there's actually no
sign of any ancient fault zones.
There is ancient beds of lava that
can still be seen in Lake Superior.
Let's see up over here.
Yeah back long time ago when the
rift was going to divide the country.
Yeah, there was lava coming up
and volcanic eruptions in this area.
Anyways, that's all I have for you right now.
Did you feel this earthquake?
If so, please put it down below.
Thank you very much for watching.
Thank you for subscribing.
Please stay safe.
Always be prepared for a disaster
and I'll talk to you later.
God bless you all. Bye.
