22 Magnitude 5 Earthquakes in 24 Hours, Why Taiwan Produced a Major Earthquake Swarm

In only 24 hours, a very small section of Taiwan was struck by 22 magnitude 5 earthquakes and 21 magnitude 4 earthquakes in what was an unusually intense earthquake swarm. But, why exactly did this occur? While these events could technically be classified as aftershocks, they occurred in a palindrome like increase before and decrease after two magnitude 6 earthquakes struck.

By experience, here in Costa Rica in 1991 after 7.7, we had 5+ aftershocks almost every hour for a day and a half, so that is kind of expected. However, this happens 3 weeks later, I suspect a local group of small faults got actived due rearregement of the area causing a seismic swarm.

@ThePaulv12 Месяц назад

So are you saying the, "No known existing parallel," assertion in the vid is in wrong?

@cjwild1 Месяц назад

@@ThePaulv12 o I think he’s saying this is vastly different than a “traditional” earthquake and suggesting why that may be. Ironically I was think something similar except I suspect the prior earthquake shifted the ground in such a way as to induce stresses on the upper rock. Overtime the rock was slowly deforming/failing till finally it began to give out all at once. At some point however something happened and it got “stuck” essentially leading to the dip and subsequent spike in activity. Just my speculation though.

That area in Taiwan is highly active. Back in 1951, 5 earthquakes of magnitude 7+ occurred in a month. Seismologists in Taiwan are now worrying about a potential 8+ earthquake as the period of 8+ earthquakes from that fault is around 105 years (the last one is in 1920).

I was in Japan when the 9.2 Fukushima earthquake hit Japan. Around 2-3 months prior to the 9.2, a magnitude 7 hit Japan, and the subsequent months had some smaller swarms and foreshocks before the big one. After the big one hit, there was so many aftershocks that the feeling of the shake became normalized. Edit: the 7 magnitude foreshock actually occurred 3 days prior to the big one, not 2-3 months.

@SparkyOne549 Месяц назад

I was watching all the quakes for months on the USGS earthquake list. I remember it all. I knew it was going to lead to a subduction event. I posted my concerns along with the question “ will there be a subduction event off the coast of Japan?” in a local seismic Facebook group, and my question had a lot of responses from so called experts, some who berated me, and the admin deleted my post from the group. Then the subduction event actually happened. I posted again, saying without saying “ I told you so”, which was also deleted.

@mollyleonard1915 Месяц назад

That actually happens pretty often there. I lived in Hualien for 30 years. Arrived just in time for the last quake season ( mid-1980s, not as large as this time, largest quakes registered at 6.8 and 6.9 on the Richter scale; several others over 6.0). After large quakes, we would go through periods where the ground would simply quiver like jello for 20-40 minutes at a time. After those quakes and several other times during the decades I was there, we had multi-earthquake series in the 4s and occasionally up to the 5s (sometimes with no major quakes and seemingly for no reason at all).The last time this happened was a couple of years after the 2018 quake (I forget which year) and covered the same general area these quakes do. If you can find it, the quakes in that series started south of Hualien and slowly worked their way north. Mostly in the 3s and 4s if I remember correctly. Figured we were working up for another big one, but it came to nothing. Don't know if you can find the data from past decades to compare to this event, but you might find it interesting if you can.

@michaelwoodhams7866 Месяц назад

Here's a simple model of earthquakes: quake magnitudes are distributed as a power law distribution. There is a 'quiescent' rate of quakes. Following a large quake, the rate increases (and the rate then decays back towards quiescent over time.). However, the magnitude distribution remains unchanged --- only the rate changes. So if a magnitude 6 quake raises the overall rate to 100 times quiescent over the next day, the odds of a magnitude 7 quake in that next day is also 100 times normal. "Foreshocks" are merely times when that magnitude 7 event randomly occurs while the overall rate is increased. This model is both obvious enough and easily enough to test that I am confident it has been tested. Can any quake geologist comment please? (The quakes discussed in this video appear to be a big violation of this model.)

Isn't it better to have multiple small earthquakes than one large earthquake? With the smaller quakes the fault slippage is being released in tiny amounts instead of one huge release. They certainly don't need an 8.5 magnitude quake, so multiple 4.5 magnitude quakes should be acceptable as more structures can withstand smaller earthquakes. I'm not saying it's good to have earthquakes but smaller quakes should do far less damage to buildings and other structures. It sure must be unsettling to constantly have earthquakes but Taiwan is in a quake-prone region, so I suppose the people are used to having them.

Well, let's just hope this doesn't turn into a very serious Event, with a continental shelf collapse or shallow incline detachment slide. There's a hell of a lot of evidence on the floor of the trench that Taiwan is hanging on the edge of that this has happened before. Also there is some very large up and down motions in the geological record, just in the last few hundreds of thousands of years here, with the mountain ranges having uplifted 6 kilometres and dropping a similar amount in just a few hundred thousand years before that. While it's fashionable these days to assume this happened at slow and steady rates, the fact is that this uniformatarianist mindset, applied to plate tectonics is dead Jim. But not yet buried. If this is a slab delamination or rollback, things could get very messy indeed. These subduction slab graveyards are full of water and it's essentially red hot high explosive mud lenses at 30km depth where these quakes are occurring. Most motion we know now is slow slip in nature. But the fracturing below the lenses, as this looks uncomfortably like, could be the beginning of a basalt seafloor slab preparing to drop rapidly into the Graveyard and potentially this could cause either a sudden very dramatic uplift, and or a sudden very dramatic drop in surface terrain.... And Transoceanic Megatsunami.
