USGS eventually learn of rock quarries, mines and other things that cause regular earth movements and they tune them out of their reporting. A rock quarry near me used to generated 3.4's a few times a week. I do not know if there is regular correspondence or schedules relayed however.
- giantrobot 6y agoI'm pretty sure blasting requires some permits. In a sane world I'd imagine blasting permits get automatically funneled into a "booms will be here" list at least at state levels. But then we don't necessarily live in a same world.
- LinuxBender 6y agoThey do require paperwork, a lot of it. One of the youtube channels I enjoy watching use every kind of demo material under the sun and they often talk about the paperwork required.
- ajsnigrutin 6y agoI'm not from usa, but EU. Here, mining operations, quarries, etc. get "booms will be here" licences, with limits (when (usually only daytime), where (quarry/mine limits and how strong the 'booms' are). So for those (rutine, standard blasts), our enviromental (earthquake) agencies don't get the data for each blast (they eg. get data, that company XYZ is allowed to do blasts up to ABC power (KJ or whatever) in location DEF, from 1. jan 2020 to 31. dec 2020 when they have to renew their licence).

- giantrobot 6y agoThat level of permitting at least let's environmental agencies get data after the fact. If they can get the place and time range of blasts they can filter that out of their measurements. It's probably some poor intern's job. Go through a stack of permits and mark measurements likely covered by the permitted blasting.
- jandrewrogers 6y agoI don't know the rules today, but at least in some parts of the US where explosives are used liberally no permits were required at all. You definitely didn't need to inform the government. This likely varies with locale. A considerable amount of explosive in the US is purchased by private individuals for all manner of purpose and use isn't on a formal schedule. Before 9/11, this was literally a cash and carry business in many States. You could back up a truck and fill it with explosives as long as you had a placard for your truck and a non-sparking liner. It simply isn't practical to track usage in many cases, even today.
- AnimalMuppet 6y agoHeh. I once wanted to dynamite my car. (It was a heap, and, you know, explosions are cool when you're young, and why not?) I didn't need any permit. I needed: 1) to prove that I was not a felon, so that it was legal for me to have access to the explosives, 2) permission from the landowner, and 3) to inform the fire department in advance (that was exactly the "booms will be here" list). Note that this was pre-9/11. Current rules are likely more restrictive.
- giantrobot 6y agoOnly now do I realize I missed my opportunity to blow up random shit with dynamite in my youth.
- h2odragon 6y agoYou've only missed it so far. tomorrow is another day. https://www.atf.gov/explosives/binary-explosives https://www.atf.gov/explosives/binary-explosives > Mixing binary components together constitutes manufacturing explosives. Persons manufacturing explosives for their own personal, non-business use only (e.g., personal target practice) are not required to have a Federal explosives license or permit. You might need to find a more remote location than a suburban backyard, however, as local authorities may have some objections too.
- giantrobot 6y agoAlso my neighbors and neighborhood dogs.
- anonymousiam 6y agoI still occasionally see "quarry blast" events on the USGS Earthquake web site.
