Good afternoon YouTubers, I'm glad you're here.
Thank you very much for joining me.
Mammoth Lakes has been having an earthquake swarm.
So far in the last 24 hours there has
been 54 and these are all above sea level.
Here we got 1 mile above sea level.
Half a mile above sea level, right at sea level.
Another one half a mile above sea level.
That's what the minus sign means, right at sea level.
Let me see what else we got.
This one here was 1.4 miles above sea level.
1.1 mile above sea level.
Almost 1.5 miles above sea level.
The largest of the earthquakes was a magnet to 3.0 that
was almost, not quite a half a mile above sea level.
What's concerning about this, all these earthquakes have been
right next to the Mammoth Lake Resurgent Dome and
they actually got some property right next to it.
We got the Hot Creek Trout hatchery, Mammoth School.
Now this image here is from 2019.
Looks like the school has been removed.
And what else we got over here? The hatchery.
I know the hatchery is over here.
As you know in the past, because of the gases
that are coming up from Mammoth, several people have died.
They've died in the hot springs that are near here.
We got the Hilton Creek Fault.
And let me bring this out a little bit.
This is the area Long Valley caldera.
Like I said, all these earthquakes have
been right next to the Resurgent Dome.
The magma comes up under the ground coming from
southeast a little bit, following along these fault zones.
Right here we have the Convict
Creek Fault and the Laurel Fault.
We also have the Mammoth
Yosemite airport in this location.
About a year ago reported about the
activity that had increased over here.
And there was an area near Mammoth Mountain
where there was over 100 acres of recently
die off of trees and dead trees.
Horseshoe Lake also had some recent die off
of trees and USGS knew in fact it
was the gases that were coming up.
And you can't see CO2 I don't know if you can see
it, but there's the area of some of the die off.
So I downloaded the data from two different stations.
Here we got LRL and we got MLAC.
This one actually is picking up the earthquakes better
probably because we got this mountain range in between.
It's closer to this Convict Creek fault zone.
They're not fudging too badly about
the size of the earthquake.
They actually did two together.
I've talked about how they've done that in the past
to get magnitudes but it's two different distinct earthquakes very
close together and so they just added it as one
and it comes in as a magnitude 3.14.
Now that earthquake was at 08:39, a.m.
Pacific Standard time and there's actually been a lot
more earthquakes than what they're reporting, which is 56,
the most recent being a magnitude 1.3, which is
this one right here, I'm going to show you
what the monitor, the stream view is showing.
But that's the last one.
They reported being a 1.3.
That would probably be somewhere in here.
Okay.
And this is what it's currently showing.
You can see there's all kinds of earthquakes.
15 right here within a three hour period.
But I come up with a magnitude one point 93.
Let me bring it down.
And they're saying it's a 1.3, but I got a
one point 93, and it's not marked in red.
This one here at 2038, they're
saying is a magnet to 2.5.
And that is exactly what I get.
Let me show you the signature and I'll bring it down.
I get the same exact two point 52.
They don't ever put up the extra little point,
but yeah, so they're not fudging about that one.
I never took into consideration what percentage
of them that they do fudge about. Okay.
This on the left is LRL.
Like I said, it hasn't been picking up the earthquakes.
And I think that is because of that mountain range.
I see.
This has got rounded tops.
This is volcanic tremors, which means
magma is moving through the system.
And you can see how we got if you got
I don't know if you can see it or not.
Let me make that larger.
Yeah, look at that.
It's all through this area.
Like I said, convict fault is where the
magma comes up through the system and then
goes up to the resurgent dump.
And let's pull it down to what it
was showing when I pulled the files.
Again, rounded tops.
So this is a good site to pull
data to see the seismic signature and see
what's going on with the flow of magma.
Lava is called magma when it's still under the ground.
I pulled the data for about not quite 24 hours.
Let me bring this down and then I'll pull it over.
It looks like it started out somewhere in here.
Let's pull this.
Yeah, see magma.
And that's not good.
It's coming in, pushing up the
ground for the resurgent dome.
That is not good.
I am sure people at the airport would
have felt this earthquake, and people that could
be working at the hatchery felt this earthquake.
And then we got a private storage unit, it looks like.
What does that say?
Let me bring it up so it shows again. Yeah.
24 hours storage, mammoth Lakes.
Oh, and there's a gas propane gas company there.
Oh, yeah, that's good. Yeah.
All right, let's pull this out.
Okay.
This is Mammoth Lakes.
This is a town of Mammoth Lakes.
What monitor we got there?
Yeah, that's the monitor that is
picking up all these earthquakes.
The best as of 2020.
There was 8263 people living there,
and the mayor is Bill Sousser.
The town is a base
for Devil's Postpile National Monument.
I think I covered that one time.
Yeah, I did because I got images of the rock formation.
This is actually a lava that fractured into hexagon
shapes because of the movement of the ground.
A lot of it's laying down.
Yeah, real interesting rock formation there.
There's the top of it.
So can you imagine the amount of lava
that flowed out to make this so tall?
You can see the trees that were growing at the top.
Let me bring this up for you, all right?
And then using Google Earth, let's go to that location where
that is at right there, and we'll bring it out.
There you go.
Post Pile National Monument.
Yeah, that was a lot of magma.
And this over here is
where the earthquakes are occurring.
Surgeon Dome.
Oh, my goodness.
I bet you the mayor is taking a lot of phone calls.
He's probably chatting with USGS.
He might be reviewing his emergency evacuation plans.
At least I hope he is.
And I hope he's not gone on vacation.
We'll have to keep an eye on this.
So, once again, thank you very much for watching.
Thank you very much for your support.
Always be prepared for a disaster.
Have a plan.
Please stay safe, and I will talk to you later.
God bless you. Bye.
