Have done some research. The most reliable stuff I can find, states that most reliable sensors, are sited well away from sports stadiums, and if you think about say maybe a Big-Foot contest, well, huge truck jumping may set off a seismic sensor at the side of a pitch?. So the pones set to sense earthquakes are sited well away from human habitation.... Yes a few sensors may have been triggered, but, not enough to trigger a warning, especially when factoring in the ignore feature on stadiums where the crowds may have gathered to watch on Big Screens etc?. So "Could you"? well, yes quite easily, but in real life, "Would you?" well, no, because you would have to have a big crowd near a sensor, which as I just said, are purposely sited away from Public Interference?. So possible myth busted that this event DIDN'T set off earthquake sensors, because those who watch them, said no it didnt?. semantics alert: the news report was that the sensors did register, but it was reported as a manmade event. I'm interested in this from a science standpoint - as in how much DO we effect our environment when we do things like that? i’m sure if nothing else, it must cause global warming. |

Something along the lines of 'can human's trigger Earthquakes?' might actually be an interesting idea, given that the show is filmed in California; so finding experts is hardly a problem. Not sure exactly what they could test. Maybe they could see what effect buildings have on the ground? |

Maybe they could see what effect buildings have on the ground? yeah, the really interesting stuff is not a good fit for the show - being along the lines of what sort of wave propagation does a manmade earthquake consist of. are we just jiggling the surface or are we actually doing something that qualifies as flexing the crust? |

Actually they could test man-made 'Earth quakes' fairly easily on the show, and in a visually interesting way;
Set off explosions of varying sizes above, on and below ground and see if the local stations picked up anything, and compare them to readings from actual crust movement. (This would require working with whatever group studies Earthquakes in their area; probably the Southern California Earthquake Center and/or the US Geological Survey so they know the exact time the detonations take place.)
They could probably also use portable seismometers, the android detection app (seriously, there is one) and even see if they could build their own seismoeters to explain how they work. (Come to think of it the latter is clearly a case of 'Can do at home' and might be a great idea for a cross over with the Junior Mythbusters series)
Its even possible that they might be able to come up with some kind of scale model to show the principles behind what causes earthquakes.

Can you imagine the fallback if the Big One hit while they were doing their tests? |

Can you imagine the fallback if the Big One hit while they were doing their tests? you think they might be blamed for it? but cyber: I'd prefer to stay away from explosives and just stick with impact testing - or heavy trucks (or trains) driving by. also would make it more kid doable if it came to that. |

There already specially designed "Thumper" trucks for seismic survey work, they could hire on of these if they can afford one.

They could get kids from the local school to jump up and down on the sports field, which would also tie into 'homemade' detectors. The latter might even be something the school itself could have some of the kids make as a science project.
'Thumper Trucks' are used for Geological surveys, so I'd guess the US Geological Survey office would probably have some they could loan MB.

I’m not sure we aren’t getting a little off track here. Wasn’t the original idea to see if people jumping up-and-down could trigger an earthquake sensor?

OK, so let's do just that. Get a couple of hundred volunteers, I'm sure that wouldn't be a problem if you put out a call for Mythbuster's fans to help out with a myth, put some seismic sensors around the volunteers and see what effect the people jumping have. Then move the sensors further away and test again. Keep moving the sensors until you can no longer sense the jumping. You should then be able to project that data to what would happen if you had a larger group of people. |

Get a couple of hundred volunteers, I'm sure that wouldn't be a problem if you put out a call for Mythbuster's fans to help out with a myth, put some systematic sensors around the volunteers and see what effect the people jumping have. Then move the sensors further away and test again. Keep moving the sensors until you can no longer sense the jumping. You should then be able to project that data to what would happen if you had a larger group of people. they can arrange the sensors like they do in blast pressure tests. and then compare their results to the thumper truck. if they do three tests with successively larger crowds, they could extrapolate the larger scale results. there is also the angle of how the dynamics of the jumping coming into sync work. (edit: I've already mentioned that, so I won't rewrite it on this post) |

Proffesional seismic survey rigs already use a number of detectors placed at a certain interval between them, the difference in when particular stations receive a signal (along with Maths) helps to figure out what the structures beneath the Earths surface look like.
I would use a mixture of what the USGS has on offer and homemade ones, to see what real seismologists detect and what the Mythbusters and schoolchildren detect.

Correction alert, I saw and am now going to have to find it again that that was a "Myth Busted", as in the original news story was maybe "Madeupium" because no one could find anything that substantiated that event?.. OK< so "Here is the news".. Its from CNN, so I suspect they have done their homework, because if it were true, that would be just as newsworthy?. Did World Cup goal celebration trigger an 'artificial earthquake' in Mexico?edition.cnn.com/2018/06/18/americas/mexico-earthquake-world-cup-goal-celebration/index.htmlAnd as the story quotes a "tweet", as a tweetering user that is highly sceptical, I can confirm there is a LOT of viral phake news on there? I am still sceptical, as I am trying to find anything at all that confirms with seismic science conformation that it actually "DID" occur. Man-made earthquake is a different story. Frakcing and other human activity can and will trigger seismic activity, such as testing BIG explosions etc?. On the actual story, Which is the background for my previous posts, that just one event registered that is close to habitation is almost on the "Ignore" list of events, micro-events happen all the time, such as building demolition, yes it shakes the ground around it, but... Can you describe it as an "Earthquake"?. Erm, No. For me anyway, others may get differing mileage?. Read that article in CNN and see what you get, you may see it different?. |

No I have always thought that although seismic stations recorded micro events it was not a true earthquake.
But surely that's part f what Mythbusters is about, sometimes it's fun to show that a myth is possible and sometimes showing that a story that has made the rounds in th news media is incorrect.
Often the media aren't lying, many of them have an arts and humanities background Journalism and English degrees etc. they simply don't understand enough about the science to differentiate between a seismograph detecting small tremors that are in no way an actual earthquake and an earthquake.

to make it abundantly clear: the news reports were that the jumping was sufficient to register on the sensors, but it was reported as the sensors registering the jumping, not as an earthquake at any time.
