Since we usually hear about earthquakes with ratings somewhere between 3 and 9, a lot of people probably think of 10 as the top of the scale and 0 as the bottom. In fact, there is no top or bottom to the scale!
Randall Munroe is the author of the New York Times bestsellers What If? 2, How To, What If?, and Thing Explainer; the science question-and-answer blog What If?; and the popular web comic xkcd (xkcd.com). A former NASA roboticist, he left the agency in 2006 to draw comics on the internet full time.

Fun fact. A magnitude 11 earthquake is calculated to have happened when the Chixculub asteroid hit the earth. The researcher who determined this found a fossil of a sturgeon that had been washed ashore from the seiches that occurred as a direct consequence from the seismic waves travelling through the earth. This happened 3500km away from the point of impact. Another juicy factoid, he determined that the fish had been hit with micro particles of molten glass. Which had been launched into the atmosphere on impact and came down 3500km further. Insane.

I like the fact that the energy levels of negative-magnitudes "earthquakes" make less and less sense but are actually decreasing at a comprehensible rate.
I believe in theory you could go even lower than the -15 example, but then you run into conceptual problems (e.g. "Can earthquakes can meaningfully be considered to occur on the microscopic and quantum scales?")
If you don't care about how the results look and just define it as "a transfer of energy from one object interacting with another", then the scale would end in meaningful terms with the equivalent of the smallest amount of possible available free energy (i.e. non-zero-point energy) being transferred between two objects, whatever that value might be. If you try to do anything different, then it becomes just as much an exercise in definition and philosophy as it would be science to get an answer. :3

@@gordontaylor2815 It wouldn't be so much about the minimum amount of energy, so much as, the minimum detectable disturbance. Eventually the quake would be indistinguishable from a measurement error (Heisenberg uncertainty) aka background noise (quantum foam).
As a geophysicist (earthquake scientist), I found this explanation extremely accurate and useful with 2 exceptions. There are no such things as "fault lines". We call them "fault zones" since a fault, especially at or near the surface, doesn't really have a definite boundary. Also, magnitude is proportional to rupture area. So a strike slip fault like the san Andreas is only about 30km deep and 800km long. While a subduction zone like Cascadia is about 1200 km long and can be several hundred kms deep. This is why large earthquakes (above 8.8) only occur here since the surface area of plate contact is much greater.
In your explanation you said that magnitude is the proportion area of rupture. How in this video relate a magnitude with the falls of things, and also with destruction of sun?
I live right on top of a fault zone then. There had been several newsworthy earthquakes with an epicenter very near my home in the south of Mexico. Is good to know there won't be any level 9 earthquakes here, I've always been worried about a very big one happening.
@@eduardoarmenta9232 If you are in southwestern Mexico, then you are located along a major subduction zone which can cause earthquakes as large as 9.0. Luckily, these only happen every 300-600 years.
also you forgot to mention that because of the way the scale works, there can't be an earthquake over 10.0, that is what the strongest earthquake could ever possible be
@@bendalton5221 There can be, but it would require an impact.

God has a strange sense of humor.
Every time you walk around, you produce tiny little earthquakes. And yes, they are absolutely detectable by seismometers if any are nearby and connected to the ground you're walking on. That's why seismometers are preferrably placed in remote areas, where they are shielded from seismic noise produced by things like traffic
A professor at the university I briefly studied at was doing femtosecond spectrography. That means resolving the energy states of particles in a timescale of 10 ^(-15) s.
Then, the city build a tram right next to the university, which seismically interfered with his measurements.
He worked around that by scheduling his measurements around the Tram.
that's a lot of text for something very intuitive that needs maybe one short sentence, if anything at all.
@@gordonlekfors2708 1053
@@gordonlekfors2708 Ok Mr. Genius, who considers 3 sentences a long essay. How about something less intuitive? A seismometer placed in a chamber in the middle of a mountain, sealed off from any air pressure changes, can still detect a changes in weather. Seismometers are so accurate that they will measure the tilt of the chamber as a result of the atmospheric pressure change deforming the mountain.
@@gordonlekfors2708 Okay, again, rude, and actually adds a whole sentence to the problem you imply exists, but let's take it as a challenge:
"The tiny earthquakes made by footsteps can be heard by close seismometers, so we put seismometers far from disturbance."
Hm... it's certainly a tad more concise, and has a little bit of XKCD simple-complex charm, but it loses a lot of its energy. LordAJ12345's version also parcels out the learning more clearly and attempts to speak to the reader, which may be better for learning depending on a few things. Conciseness is only useful insofar as it suits its purpose; here, the purpose is clearly to teach the passerby, which presents limitations other than simple efficiency.
It's crazy how many earthquakes are caused by house pets every day.
Yeah, I really should stop putting coins on my dog's back.
crazy how as im typing this im doing earthquakes
I was a kid in Bremerton when the Good Friday quake hit.
The epicenter was nearly 1,000 miles away in Alaska, but it broke windows in our house, tumbled our neighbor chimney.
And that was 'only' a 8.4-8.6!
Wikipedia says 9.2 tho. in the 70s or 80s almost all intensities were recalculated from Richter to Mw scale. Valdivia 1960 changed from 8.6 to 9.6
for anyone confused why it gets so powerful so quickly, the scale doesnt increase linearly, it actually multiplies by 32. for example, a magnitude 8 earthquake is 32x stronger than a magnitude 7, and a magnitude -3 earthquake is 32x weaker than a magnitude -2.
Wouldn't the difference between of 32 times the amount of power be ~1.5 difference in magnitude?
I'm not really sure how the math of it works. I see online that a difference of one magnitude seems to 31.667 times the energy released, but how come it is measured as 10 times bigger then?
I kind of conceptually don't understand I suppose.
Also, now I'm curious.. does a negative powered earthquake represent anything real?
@@wolfxlover I don't understand what you're asking.

Side note, it's believed that the strongest earthquakes that have happened on earth were due to impactors, for example it's believed that the asteroid that killed the non avian dinosaurs caused a magnitude 11 quake.

I admittedly knew a decent amount of this given that I live in an earthquake prone area, but I didn’t know that the numbers could be negative or that pushing the upper limits would straight up just blow up the earth
Didn't know they could blow up the damn sun either.
Yeah... welcome to logarithmic scales and exponential functions. Each increase of 1 in earthquake magnitude multiples the energy release by 32 (it's a factor of 10 in shaking amplitude, but that translates to a factor of 32 in energy release.) So, while a magnitude 6 is 32 times more energy than a magnitude 5, a magnitude 15 would be around 32^10 = 1,126,000,000,000,000 times as much energy as a magnitude 5 (and, on the flip side, a magnitude -5 would be 1/1,126,000,000,000,000 times as much energy release as a 5.)
But is it really an episode of "What If?" if we DON'T blow up the earth?

So you're saying that magnitude -15 quakes are happening around the world all the time? Neat!
Based on the examples in the video, that's true of any magnitude -3 or below (well, down until the point where the energy values get low enough that the quantum nature of energy prevents going lower). People drop their phones all the time. -2 to 0 are probably pretty common too, since something like a piece of furniture falling over would probably be somewhere in that range.
Oh, and about that lower limit: according to Wikipedia's "Orders of magnitude (energy)" article and the Richter Scale formula, the emission of a single AM radio photon would be around magnitude -21. I'm sure there are lower meaningful values (I suspect something like "a single electron hitting your table" would be lower, but I'd need to spend a little more time remembering the physics on collisions before calculating the true minimum meaningful value).
Just a person working in an office would be a rapid fire of magnitude -6 earthquakes. Or -5, if they have a nicer keyboard.

I thought it was an xkcd article that said magnitude 40 on the Richter scale would release an equivalent amount of energy as the Big Bang itself, so, you know, all of the energy.
Accounting for the energy of the big bang is tricky. For one, many cosmologists believe the universe has exactly 0 total energy as a result of a balance between gravitational binding (negative) energy and mass-energy etc. For another, if you want to measure a particular component of this, the answer is probably infinite in most cosmological models which model the universe as infinite. I think the best you can do to get a nonzero finite answer is ask for the mass-energy of the observable universe, which is about 10^70J, or a magnitude 43.

Having read every comic and book that you've published, I'm very excited to see you branching out into videos! And with wonderful quality right from the start, no less.
I was in SF for the Mendocino earthquake - 7.2 - in 1992 and that was the single most terrifying moment(s) of my life.

There's nothing you can do except cower and hope you don't get crushed like an ant, or worse. It lets you know just how fragile and mortal you really are unlike anything else.
I think a main point missed is that the Richter scale is logarithmic. A magnitude of 8 releases 10 times more than 7, but 9 is 100 times more powerful than 7.
Yep! At 15, nothing remains but oceans.

@@mathcookie8224 Just a heads up, we indeed do not see your next comment.
I remember one of my geology professors saying if you were to cut the Earth in half and rotate it (either half way around or all the way, I can't remember which) you'd have a magnitude 13 earthquake.
wow these stick figure illustrations are cool!
He should start a webcomic!
I caused a magnitude -4 earthquake to watch this video.
I was literally just thinking a couple days ago, i need some more xkcd , & I wondered if there were youtube videos and i thought, Nah, it's a comic thing, not videos......Silly me 😄
I am so so delighted to have been wrong.

Randall’s on UA-cam now? Subscribed, liked, anything you need! Been reading xkcd since comic 700 or so!
XKCD’s humor translates amazingly well to video! Keep it up!
This is what I love about exponential growth. Going from -15 to 15 on the scale goes from dust particle landing on a table to the complete destruction of the sun.
sun destruction is 25
Earth destruction is 15
*earth
the video shows the sun handling up to 24 ;)
@@Xnoob545 whoops! Good catch, guys.
15 is only enough to boil ocean, but for sun it is only a coffee every its morning
a cme has enough energy to melt earth
and every second sun turn enough hydrogen into pure energy to be equivalent to magnitude 15
If caseoh fell it would be a magnitude 24 earthquake
One unfortunate loss in this format is the hover-text. I'll miss the hover-text.

Hey! I've been a fan of your comic since I got the original 'What If?' for my birthday. I then went on to get complicated things explained with simple words, and the second what of book. I love your work, and this new voiced video series is super exciting! Keep it up, and have a wonderful day!
I'm sure it's just a coincidence but thinking about negative scale earth quakes brought me a sense of peace. A mote of dust coming to rest on a window sill.. ahhh
0:41 not just 2, but 18 earthquakes in recorded history in 9.0 scale
