My neighbor hears it...My cats hear it. I live in Sahuarita, but i heard it at my in laws place in Rio Rico (it sent their dogs into a frenzy), and I've heard it in East Tucson with my friend (who could hear it as well)

Maybe mine blasting? Anyone else experiencing this?
I've been hearing this exact same thing and live in Tucson near River between Swan and Craycroft. It seems to really get active around 2-4am as you said, but I've heard it even later in the morning than that. It's a very low frequency hum that will cut down to even a lower frequency hum that is a little difficult to hear. I can hear it outside as well if it's quiet enough. Not sure where it's coming from, it seems to be coming from all over. It doesn't take much other noise to wash it out, but it's definitely there. I rule out pool pumps because the hum will last a random amount of time and pool pumps are generally set to run for a set amount of time, usually in hours. There is no vibrato to the hum either - it's very constant in frequency.

It doesn't annoy me, but I really wonder about the source.

I agree with Marcy, probably aliens. I would think that they visit early in the morning when there is less of a chance of being seen and they probably leave their saucer idling. Remember the low tones in the movie "Close Encounters of the Third Kind" when the mother ship appeared?

Default Rumblings shake house

I live in sahuarita. For 9 yrs now n I've always hv heard booms n rumbles that u can hear when outside and rumble the house when inside. They're so loud that the cats look all shook up. People say it might be the sonic booms of jets and they're not. I know how those sound. Others say mining,but that's not it either. I work at Freeport when they blast in the pit. I've seen it n we get to see the blast n u hear it but we r not that far away and u don't even feel it. So the only thing I could think of is earthquakes, but r they that loud? It happens always in the mornings. Usually 8,9,10 am. No one can explain them.

My neighbors in Green Valley mentioned hearing booms, but they said it was mine blasting. I am not sure how they know that. I live a couple of acres away and I did not hear anything. Go figure!

In Hawaii, they claim that low rumble is the volcano.
In California, it was blamed on the freeway.
I'm in SW Tucson now, hear something similar now and then, thought it was traffic related.

Since I first posted here in 2013, I've moved a little farther west in Oro Valley. I used to be in La Reserve, and what I heard then was a high pitched whine. Not loud, but there and once you're focused in on it, it seems it was happening all the time. I was told then it was "the mine". I only heard it at night, and only in winter when I had the windows open at night.



Now, I'm in Rancho Vistoso near First Avenue and Tangerine. I hear the rumbling day or night and usually once a day for both. It's like a low rumbling, almost like a big rig diesel idling. It doesn't rattle the windows or shake anything in the house. I've gone out in the back yard, front yard, and I can hear it, but I don't feel the ground rumbling. I live near a fire station and I used to think it was a ladder truck going by without lights or siren, but when I go outside, there's nothing there, just the low, rumbling. It's hard to pinpoint where it's coming from, or whether it's underground or above ground. Again, some of my neighbors hear/feel it and others look at me like I'm losing my mind. Those who hear it again attribute it to "the mine". I have no idea what mine they're talking about. I'd love to know what it is.

This is interesting, Marcy. I wonder if the prevailing winds have anything to do with the rumbling being more noticeable at certain times. Do you ever get winds from a southerly direction? (mines located along I-19, south of Tucson). Or perhaps sound travels underground along the path of a freeway or pipelines. If not, maybe there is road construction going on somewhere. I do like a good mystery.

Some aspects of the phenomenon is still partially unexplained, but the gist of it is this: sand is composed of several minerals, including tiny pieces of quartz. When you squeeze a quartz crystal, a tiny bit of electrical potential is created. So in a sand dune, the sand under the surface is being compressed under its own weight and when the top of the dune shifts slightly from the wind, trillions of little quartz crystals are being triggered to release a tiny bit of electrical potential - and some of that potential is released as an audible sound. There is tons of information about this phenomenon, and here is just one of them: click here.

Hope that helps.
That's all very interesting, and I like the video of people sliding down a sand dune.

But where are the sand dunes causing this? I'm on open land. The soil isn't sand, it's silt, and it's all stuck together, not loose and flowing.
