    There's a lot of people in this thread who see "North Korea" and "nuclear test" and get fired up but would otherwise shrug if it were instead, say, "Oklahoma" and "fracking".

    The supplemental information is available and says: > Our earthquake catalog consists primarily of small events with magnitudes of < 2.0 and there were 1399 of them.

    The cited Ren&al says: > The magnitudes of these seismic events primarily range from 1.5 to 2.5 and that there were 647 of them.

    USGS (<a href="https:&#x2F;&#x2F;www.usgs.gov&#x2F;media&#x2F;images&#x2F;earthquake-and-energy-comparisons-updated-2025" rel="nofollow">https:&#x2F;&#x2F;www.usgs.gov&#x2F;media&#x2F;images&#x2F;earthquake-and-energy-comp...) says that a magnitude 2.0 earthquake is the equivalent energy of 56kg of explosives, which is more than I&#x27;d want to be around but I think for people who actually use the stuff it&#x27;s not a lot.

      It&#x27;s simple, really. Fracking has offsetting pro-social benefits in a way that NK possessing nuclear weapons does not.

        “Pro-social” is a strange way to describe something that’s actively contributing to the death of our civilization.

          Looked at another way, shale natural gas has largely displaced coal which emits more CO2 and can be burned in the same power plants. This base load allows for more wind and solar. Natural gas is a great bridge fuel.

            I don&#x27;t believe nat gas is burned in the same plants as coal.

              Most &quot;closed coal plants&quot; in the US are really plants that retrofitted to use nat gas.

              here&#x27;s a decent recap (now a couple years out of date)

                Ah, cool.

              It’s a straightforward retrofit.

            If you could remove a gigaton of usable coal from the world and replace it with an equivalent amount of natural gas, that would be a nice improvement.

            When the natural gas is displacing coal by being cheaper, that&#x27;s pretty bad in the long run. We&#x27;re still probably going to use that coal later, and cheaper fossil fuels reduce the price pressure to install renewables.

            1. ch4s3 · · focus · HN ↗
              We probably won’t go back to coal, most of the cheap high quality surface level coal is gone and we have a lot of natural gas. We also may see a resurgence of nuclear power and a lot more solar of course.
              1. Dylan16807 · · focus · HN ↗
                If we were running out of cheap coal anyway then we would have been better off without the surge in natural gas.

                Higher prices would promote a faster shift directly from coal to solar (or nuclear if the price works out). And there was already enough natural gas production to fill the gaps that solar, wind, and batteries can&#x27;t fill.
