The AAAS Science article reporting on the study reaches 142 points and 115 comments on Hacker News, sparking discussion about the magnitude of earthquakes, geological risk, and comparisons to induced seismicity from other human activities.
“North Korea's underground nuclear tests have triggered a chain of seismic events, activating ancient fault lines that stretch towards one of the most dangerous volcanoes on Earth, about 100km (62 miles) away”

This threw me into a rabbit hole for a bit. Apparently there is good evidence that a lot of historical earthquakes in california were due in part at least to the oil industry, which early on would not replace pumped out oil with water.Now a days they claim they replace the oil with water and all is well. However, as anyone who has owned an ancient…

Interesting. The nuke tests have stopped... but the earthquakes haven't - https://www. science.org/content/article/no rth-korean-nuclear-test-sets-years-earthquakes - Via Science.Org

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…

Geologic systems are more complex than this. Analyzing something like this as though it were a single system is wrought with the dangers of miscalculation.You could locally release stresses on an incremental, short term basis this way in a local system, while at the same time increasing stresses on nearby systems which could fail even more…

Reminds me of a display at Chabot in the bay area. A bubbling volcano covered by a stable mass stays bubbling underneath, but shaking up the mass gives little bubbles a bath up and they break way for the big bubbles leading to a volcanic eruption. If you fragment a he soil at some point in the mantle of earth and there is pressure anywhere below…

It's logarithmic so you'd need more like 30,000 magnitude 3 earthquakes to equal the energy of a magnitude 7. I don't think it's clear this is better. You can also make the argument that this may trigger the large earthquake that might not have happened for a long time.
-
Could this be considered a good thing?The energy being released in these many tiny earthquakes was always going to exist in this location. Much better to release it slowly via thousands of tiny earthquakes than all at once. Better to have 10k magnitude 3 quakes than one magnitude 7.

I always wondered where and how my country would test nukes if it developed them. Basically there is an expectation that you have to explode at least one.It was much easier in colonial times when everyone owned a desert or remote island
-
If you have an anvil hanging over your head, the potential energy that would kill you already exists. Slowly lowering the anvil makes sense. Damaging the rope holding the anvil doesn't.
-
This article does a very poor job of differentiating earthquakes people feel and care about versus magnitude 2 quakes that are like your neighbor dropping a book upstairs.
-
When gas extraction caused earthquakes in Groenignen, this site was very clear on prioritizing fossil fuel extraction over a few small tremors.
-
The long delay is the interesting part to me. How do they distinguish earthquakes triggered by the test from normal background seismicity?
-
It's simple, really. Fracking has offsetting pro-social benefits in a way that NK possessing nuclear weapons does not.
-
Is this safer overall? Should we give kids a day off from school and detonate a midsized nuclear device near Los Gatos?
-
It can go either way, you might get a relief of pressure or you might get an increased destabilisation in the region.
-
Fracking doesn't result in potential nuclear fallout or the likes of Seoul or Tokyo being held hostage.
-
Curious how we never get articles about the harm caused by western countries nuclear tests...
-
How long until someone attempts to diffuse a pent up fault line via nuclear geoengineering?

Basically, they gave their land Atrial Fibrillation through strong extrasystoles.
