Can you predict an earthquake?

For decades, researchers like Dr. Bob Herman relied on paper and ink to study earthquakes. The Raspberry Shake helps geophysicists get more data around the world as citizen scientists can participate in ShakeNet, a global aggregation of real-time seismic data!

As a scientist, I can relate to spending most of my time preparing the data. That hasn't changed, the difference now is we write programs to compute terabytes of data. Very cool to see this evolution in a different field.

The noise isolation reminds me of LIGO, had a friend who did his undergrad work with the project, most of the early days was figuring out how to filter our local noise. He sent me a recording once of a telephone call he was able to decode back into audio that the equipment had picked up.

[@JeffGeerling]

It's incredible what data can be pulled out of a signal most people would think is just noise. Dr. Herrmann and I talked about a lot more than just what was covered in this video-he mentioned he did a number of studies on the local noise at SLU in the 2000s, I think, around the time when I was a student there!

[@Rafy_24]

I worked for a while in a Scientific Center about geology. Its a fun and amazing science. Nowadays its all digital. GBs of data. The sensors are really sensitive tho. You can "track and see" storms, fireworks, cars even planes and lighting bolts. We even detected a meteorite that entered the atmosphere near by. Seing something like this using the raspberry pie is just awesome. A global seismic network of raspberry pies :D

[@0tiochico]

This video was super awesome and i can very much relate to that. In my undergrad days i used to monitor a seismic station 10 years ago, complex job, lots of math and programming involved. I'm not from the generation that used smoke paper or analog sensors, but we had an broadband seismometer connected to and old pentium PC. I've always thought how could it be to make a simpler yet effective seismometer using some small chipsets, and now we have it! Seeing the professor using Linux command lines and combining and stacking various seismograms to determine it's where it happened and magnitude reminded me when i used to do it. I remember a fun day, when i basically freaked out when i picked up the 2011 earthquake in Japan (that caused the fukushima accident), i went running to my supervisor to warn him, that same day a reporter from the local news came to interview us about the quake. Outstanding day!

[@raspishake]

[@earthling_parth]

I totally understand the price working as a software engineer how software upkeep and infrastructure in cloud/hosting would be a big part of the cost. This is an amazing global citizen science project which is crucial and extremely helpful when researchers want to understand a specific seismic event.

[@SeanHodgins]

There is a bad pothole/manhole cover on the road near me and big trucks are constantly shaking my house during the day when they hit it. I don't know how useful my data here would be. But maybe I could find some exposed bedrock near by and setup a remote solar/battery shake on LTE. That would be neat!

[@JeffGeerling]

Definitely! Networking is sometimes the hardest part, because to get better data, you want to be isolated from structures / deeper in the ground. That's precisely where wireless signals can't get :D But if you can run PoE to the device, you could get by with one Ethernet cable to it.

[@wayland7150]

It might be useful data to get them to repair the pothole.

That data telling you about the washing machine and dryer is great to be able to automate and work on things, lights can flash when the laundry is done, you can monitor all kinds of things that produce a change in the air pressure and vibrations in the house and setup automations to respond to those things. It seems like it may also be sensitive enough to combine with a power sensor to quickly identify what appliance is causing a power draw and a whole bunch of other ideas. This is so neat.

[@johannnn]

I have so much respect for all these scientists who have been studying their fields for 20+ years. It's incredible!

[@rayoflight62]

I have operated a swiss-made smoked paper seismometer up until 1984; they were particular cheap to operate. Normal seismometer like the famous Geotech S-13 are velocimeters, as they measure the prime derivative of the Earth movement, with a cutoff frequency of 1 Hz. The geophone used in the Raspberry are accelerometers, measuring the second derivative of Earth movements; a measure of less value. The true value of Raspberry sensors is their networking, and the filtering and crosscorrelation of data. The true forecast job can only be conducted with the study of telesismology, measuring Earth movements with a period of 20 seconds up to an hour. I believe this type of information cannot be extracted by the Raspberry Shakes.

[@lfarge]

[@UTubeRangerBob]

I was an AFTAC nuke sniffer back in the 70s-80s. Then went to work as a contractor for USGS. And finally for the NSF/IRIS EarthScope project. I've worked on just about everything seen in this video including the Benioffs. While working for USGS I had to replace a set of Benioffs with fancy new Streckeisen sensors, which look a lot like the Nanometrics Trilliums seen here. I had to haul the 3 Benioffs on a sled behind a snow machine across a frozen lake in Kevo Finland. Had to scoot across as fast as possible because the ice was cracking due to the weight of the Benioffs. Seen but not mentioned in the video is a Quanterra Q330 digitizer. Every product made by Quanterra is named after a John Deere tractor because the company founder is an old tractor enthusiast. The JD 330 was a johnny popper from the early '60s. Also seen but not mentioned is a Kinemetrics EpiSensor strong motion accelerometer (black hockey puck-looking thing in the middle of the pier). It's used to record the really big and/or local quakes that would over range the more sensitive seismic sensors.

Jeff. Great video, as always! And thanks for the balanced explanation on the price. It seems counter intuitive that they have a network that they want people to contribute to, and benefit from more contributions, but charge a significant premium for those participants to contribute. Especially since the contributors likely get far less from the net data output than the global program does. It'd be nice to see if they were able to secure funding to cover their operating costs and flip their model. I'd expect they'd be able to get *far* more participants - including schools all over. Probably unlikely at this point given how many people have already bought into the model though.

But the buildings and infrastructure were built for this (as well as they could be). The island is the peak of the underwater mountain where the Marianas Trench is, the deepest part of the Pacific Ocean. I'd be certain there are some Geologist stations/equipment there!

I quite like the idea of contributing towards research. But i feel that a university/research council should subsidise at least some of the cost since they're the group that will benefit from it. Eg. I do folding at home and all i had to pay for was a used computer and the power to run it. And if not subsidised, it should be open sourced to drop the cost.

[@WobblycogsUk]

@@Shocker99 I had a good look at their offerings after the video and it seems they are subsidised, probably. Home and education users get a $125 discount but commercial / government pay full price, I assume one subsidises the other. That still puts the DIY kit over $200 though (and I'd need it shipped internationally as well). If I was into this sort of science I'd definitely buy one but it's a bit much for just interest factor.

Fascinating. I live in Southern California and have lived through several large earthquakes. During the Northridge quake, I was far closer to the epicenter than I would have liked. Since then, I have attempted to come up with various mechanical ways to record earthquakes, but this looks like the best idea yet. I have a few spare Raspberry Pi's around here, and it appears they sell "partial kits" of parts, so I suspect I will soon use one of them in a build project. As a graduate of St. Louis University, I was proud to see you included them in this video. I, too, took "extra" classes in weather, simply because they were available, and it was back in the early 70's when Dr. Fred Bates was the head of the meteorology department. He was the original tornado chaser, using his hand held 8 and 16mm cameras of the day, proving his theory that there are far more tornadoes than what was being reported. Today, we know that was true because we have the many, many storm chasers who document it every year. Dr. Bates, and a couple of other professors at SLU, cultivated my intense interest in atmospheric weather.

[@JeffGeerling]

That's amazing! I only took a couple semesters, so I got some TAs, though one of them went on to go into broadcast and is a meteorologist somewhere in Tennessee now. I assume you subscribe to Pecos Hank? I love his videos, and feel like he's one of the best tornado chasers in the world today.

I like to do audio recording at home all the time and I edit with Audacity. I live in a 2 story home with neighbors upstairs. Sometimes when I am recording, I can detect when they walk or move around. There will be a flat recording line and then what looks like the waves on a seismometer graph. If I slow the speed of the recording down, I actually hear what sound like rumbles which I think is pretty cool. I was thinking of burying a large drum in the ground and suspending a microphone from the center to see if I can detect any movement. It might not be an accurate or official way but it will show me if there was some kind of vibrations from the ground.

[@suki4410]

[@michaellehman1549]

Neat that you can do that with a Raspberry Pi! I just might have to take the plunge and get one. Interesting comments about AFTAC. It was a major funder, although in secret, for a vast expansion in academic resources devoted to seismology in the late 1950s and early 1960s. The 1953 Limited Test Ban Treaty drove most nuclear testing underground due to the fallout it created, an eventuality that the Air Force saw coming and wanted to be prepared for. Fallout analysis had provided a vast amount of information of Soviet weapons. While the possibilities of doing that with seismology were considerably less, AFTAC wanted to extract everything it could. There was also considerable controversy. Proponents of a comprehensive test ban that would prohibit all testing argued that seismology was sensitive and accurate enough to enforce such a ban. The Air Force and others argued that it could not do so for testing in the kiloton and below range. Based on what I've seen, such a total ban was feasible, but the military didn't want to go there, supporting the eventual 1963 partial test ban instead, so that testing could continue underground. There is an interesting group of papers in the American Physical Society's library in the DC area that provide a good background on this controversy which I had the privilege of reviewing while doing research on my dissertation, "Nuisance to Nemesis: Nuclear Fallout and Intelligence as Secrets, Problems and Limitations on the Arms Race, 1940-1964.," which discusses the role of AFTAC, nuclear intelligence, and their strategic implications on the arms race. You can get a free copy of it at hdl.handle.net/2142/90554

[@UTubeRangerBob]

Ex-AFTACer here, '78-'84. 'In God We Trust, All Others We Monitor!' We did much more than seismic detection. Each detection method, which we called a 'technique', had an arbitrary letter assigned to it, though quite possibly based on the order it was implemented. Seismic was 'B' technique. I know they went down to at least 'T'. I also ended up working for the Defense Nuclear Agency (DNA) as a contractor doing HE testing (simulated nukes) at WSMR and subcritical testing at NTS. One of my last assignments with DNA was running the transparency instrumentation that would prove that we didn't violate a treaty by going critical.
