    I was working on the Pacific Northwest coast in a small coastal town that was built on mud flats and wood waste from sawmills. The Nisqually Quake occurred while I was outside a pump station and I watched the ground making waves across the area , much like what you see when wheat fields are being blown by a gentle wind. I saw sand blowing out of cracks in the asphalt streets during this event.

      @Memes Are KEEM tall buildings in earthquake zones are designed not to fall in earthquakes, so they don’t. The glass on the *outside* of them however will, then it will fall dozens of feet onto anyone who ran outside and wasn’t able to get more than a few feet away from the building before it started raining glass because earthquakes happen very fast. Short buildings in earthquake zones also won’t fall during an earthquake; the only difference is that the glass which you run into when you run outside won’t be falling as fast

      @Riverside it feels like the contradictory opinions are just answering different questions.
      If you’re in a large suburban sprawl then probably going outside would be safer, because there’s lots of outside, the buildings aren’t tall, and with the way single-family homes in the US are generally structured, there often isn’t much stuff on the outside to fall off.
      In a denser urban environment however, staying inside is definitely safer, for all the reasons people have been talking about.

    These are used primarily in oil and gas surveys, called vibrators. A whole fleet generates a wave of large magnitude and the resultant sound waves are picked up by geo phones . The collected data is produces 3D slices of geological mapping

      Yep, that's seismic surveying. They complement the data they get with ground based gravity surveys (a box with a spring that you precisely measure it's stretch at a certain temperature) as well as aerial sensors on aircraft.
      Travelled all over Australia and northern Canada doing this. Best job I ever had.

      Twelve years ago I watched a formation of trucks like this drive in sync across the Kuwaiti desert near a military base. They'd all stop simultaneously for a minute or two, then continue driving (still in formation) to whatever the next spot was during their surveys. Unfortunately I was too far away to actually feel/hear shaking.

    Had the interesting experience of the purely vertical shakers being used in the middle of the city a few years ago. Seismic testing for geothermal energy. Fun when they are right outside your window, and you are on one of the upper floors of a late 18th century building. Been in a few earthquakes in Japan, and was rather odd to suddenly get the same feeling in a geo-stable city in the middle of Europe.

    But I'm sure these nice folks at the University of Texas would never do something like that, right? *Right?!!* 😉😂

    • Jedi Sentinel

      you dont have to precisely time it at all. every time the camera took an image the shaker would cycle once, so we have no way of knowing if it was at the top, middle or bottom of its stroke. it just was in the same spot because its cycle rate matched the cameras framerate.

    Something similar was brought in to test the subsoil before engineering the final specs that the Cape Hatteras Lighthouse was lowered onto or should I say lowered to the appropriate grade with high psi bricks filling the gap between the huge block of reinforced concrete and the base of the granite foundation where the cable saw cut the original sub-grade foundation off. The actual foundation was pine beams which were perfectly preserved by being under the water table which was a huge surprise but further inland at that depth there is a lot of organic material hence the testing.

    I work in passive source seismology where we just wait for the earthquakes to happen and use that data, but I learned quite a bit about active source in my undergrad. I once heard a story about some researchers at a university who wanted to use a hunting rifle as their source, but it was too weak. So they got a Browning M2 Machine Gun. The airwave from the explosion however was affecting their sensors, so they mounted it on a cherry picker to get it higher off the ground. Better, but it was still an issue - so they decided to try and redirect the hot gases coming off the barrel. Their solution? Put a condom around the barrel. The final bill for their project included 2 Browning M2’s and 10,000 condoms

    Growing up on oil rigs on the Omani desert in the 1980s, we had similar but not identical pieces of equipment, we called them “thumper trucks”, used for seismic exploration for oil. A line of them would drive across the desert, pause, then all would drop their enormous weights at once to create a shockwave, which another truck a set distance away would read and produce a seismic survey of the rock strata underneath as they progressed forwards.

    27hz is the highest frequency my sub can play at 0db before dropping into nothingness (-120db) at 23hz, thanks to some EQ magic pushing the roll off point down to the physical limitations of the driver itself. I had to turn this thing down while it was pummeling the ground lmao. The high end was actually louder but it was also rumbling my room a little bit since I usually listen to your videos quite loud anyways. I've got a bit of experience causing miniature earthquakes myself, except we always did it using standard concert PA speaker stacks, during sound test before a large show! We'd flip a bunch of subs over on their face, so they created a compression chamber out of the entire horn, which lets the sub run more efficiently while transmitting the energy more effectively into the ground. If you hit the ground with enough directed sound energy all at once, you might get a visit from the local USGS team while they investigate what the hell is going on! Great people those folks are, we had a good laugh together once they realized what we had done.

    I grew up in Nevada, in a geothermal rich area. I remember, as a kid, these series of trucks that drove through the area. They were going very slowly, and one of the trucks was shaking the ground. What they were doing was using sonar to see the cavity underground of geothermal activity. It very much felt like an earthquake - just, an earthquake that lasted for 5 seconds, every minute and a half, until they were out of range.

    In the mid 70's a company came through our town with a machine like this. The day or two before they came by and drove a bunch of sensors into the dirt. Truck came by and sat in the street and did the vibrating for about 30 seconds. Then it picked up and moved about 200 feet down and did it again. I believe the whole point was subsurface oil or gas exploration.

    I remember when I was a teenager - so we're talking back in the 70s - coming back to sixth form college after the summer break, and many of us had had summer jobs.
    One guy had been working for an oil company - perhaps BP, I'm not sure - but they had a similar vehicle, which was used simply to drive around the UK, park in designated spots, and do similar testing. Probably not to these levels of force, but the purpose was for oil and gas surveying, and they were taking seismometer readings back for analysis. Thinking back, it might have been in preparation for fracking.

    They use this for oil and gas exploration as well. Installed sensors all over the place, closed all streets and forbade all the farmers to use their tractors and then they drove around with a rattler like this which helped them exactly locate the resources

    Aha! That's what that machine is! I saw one of these at a dam near me, driving (and getting stuck) on the dam wall while the water level was low. I knew they were installing some kind of seismic sensors, but couldn't figure out what the truck was.

    Shakers have been around for decades. While working at UT at Dallas in the 80s, I designed a remote radio control system to control one out in the Nevada Test Site. I sat on a mesa at night and used it to synchronize my recording truck with the shaker thirty miles away.

    I would like to add that this is in no way a new technique. Colleagues of mine used this type of machines already 20 years ago to explore the underground for geothermal potential in western Europe. They were typically able to "see" about 2-3 miles deep.

    I'm sort of confused as I was working with a seismic exploration company that would bring in up to 3 of these type of shaker trucks and that was back in 1983. Granted they weren't using it for earthquake analysis. You could program the shakers to run through a complex signal to inject into the ground to pick up on the sensor lines for "looking" under ground at the various strata based on the return picked up at the sensors. This was advanced back then when other strong signals were used previously by the geologist world.
