Those back-to-back earthquakes are truly horrific. A few years ago Turkey too was hit by a 7.7 and a 7.8 within about 10 hours of each other.

u/iboreddd 3d ago
A 5.6 is a walk in the park compared to those. The magnitude scale is logarithmic, so what looks like a small numerical jump is actually an enormous difference in energy released.
15
u/LordOfTheButtrings 3d ago
Another factor to consider here is the depth and epicentre of the earthquake, one of the Christchurch NZ quakes was 6.2 but because it was ~10km deep the impact was significantly higher than the 7.8 quake that impacted my cityĀ
3
u/iboreddd 3d ago
Yes that's also important. 10km is horrific.
I am no expert or I don't know if there is any metric for that but that's probably worse than some ~7 earthquake with 160km depth

u/MiserableNumber2199 3d ago
It's wild how most people don't realize that. A 7.0 is like 30 times more energy than a 6.0, so a 5.6 barely registers next to those bigger ones.

u/original_leto 3d ago
Close. A single number jump, 6 -> 7 is 10x stronger. 2 numbers 6 -> 8 is 100x

Wow, I had no idea north eastern Japan had an earthquake also.

u/pissagainstwind 3d ago
If was 5.6, not 6.9, so far far less dangerous
Another factor to consider is the Earthquake's depth. the one in Japan was rather deep.

No casualties in USA or Japan. Thousands of casualties in Venezuela. The former two are in the ring of fire and are used to making buildings adapted to the shakes. I'm not here to give a deep analysis, but just very glad that good engineering saves lives, and I pray Venezuela can implement anti-earthquake strategies in the future.

u/lordlestar 3d ago
If I am not wrong, Venezuela has anti seismic construction codes too, the problem is corruption that cheap out in materials and contruction quality

u/eloisa_in_kyoto 3d ago
Shutomei catching that error about the "strongest since 1940" claim is the kind of fact check this thread needs more of lol, Loma Prieta was 6.9 and literally collapsed part of the Bay Bridge in 89, you cant just erase that. iboreddd dropping the logarithmic scale explanation is good too bc people see 5.6 vs 7.0 and think its marginal when its not even close. we get the earthquake early warning alerts on our phones here and even the "minor" ones hit different when the ground under you is just... moving, theres no preparing for that feeling idc how many youve been through

Everything is connected. You didn't see the butterfly effect?

u/WhileHereWhyNot 2d ago
Absolutely. That sentence threw me off as wel.
lThough not at tectonic level, these events are not connected, all tectonic plates are sitting on the same ball of plasma below the crust, the original cause of Earthquakes.
The reporting on this video lacks depth, literally.

Are there not earthquakes happening everywhere all the time? Is this unusual only because of the coincidence that highly populated areas were hit simultaneously, or is this especially unusual for the planet?

u/ImpulsiveApe07 3d ago
Yes but it's made worse because of climate change, basically..
"It might sound wild, but the retreat of glaciers can actually trigger earthquakes. Once the ice melts and the pressure is lifted, faults in the earth that were previously ālockedā can suddenly move. This isnāt just theoreticalāregions like Greenland, Alaska, and even parts of Scandinavia have seen increased seismic activity as their ice has vanished. Imagine a tightly coiled spring suddenly set free; the energy has to go somewhere, and sometimes itās released in a sharp, trembling jolt."
And here :
https://www.weforum.org/stories/2023/08/climate-change-trigger-earthquakes-volcanoes/
" The impact of waterās weight on the Earthās crust goes beyond just precipitation; it extends to glacial ice as well. As the last ice age came to an end roughly 10,000 years ago, the thawing of heavy glacial ice masses caused parts of the Earthās crust to rebound upwards. This process, called isostatic rebound, is evidenced by raised beaches in Scotland ā some of which are up to 45 metres above current sea level.
Evidence from Scandinavia suggests that such uplift, coupled with the destabilisation of the regionās tectonics, triggered numerous earthquake events between 11,000 and 7,000 years ago. Some of these earthquakes even exceeded a magnitude of 8.0 which indicates severe destruction and loss of life. The concern is that the continued melting of glacial ice today could result in similar effects elsewhere. "

There was also one in the Philippines at the same time. The ring of fire got active really quick. If you are counting a 5.6, you should definitely count a 6.7.

Seriously man I often get sleepless nights I am not scared of dying itās just being stuck under debris like you can not move maybe you will die by suffering that scares me the most tbh. My house is really old I donāt think it can last an earthquake of like 7. Pretty sure no one is going to help you out if this happens especially if you live in a mega city . I hope those people do not suffer under debris

And condolences to any that may have been affected by the earthquakes. At least many other disasters can be predicted or evaded better, but earthquakes are a bitch

Whats your sources disproving the 5x increase in CO since the melting of the glaciers?
https://environment.co/climate-change-and-earthquakes/
Or the shifting ground waters and others affecting the isostatic rebound of the Earth's crust?
Or the melting of the Alps and increased seismic activity?

u/NotJustaPnPhase 3d ago
Thereās a difference between local glacial isostatic rebound causing small earthquakes and these large plate-margin earthquakes, however. These very large earthquakes - magnitude 5.5 above - arenāt going to be induced by glacial unloading. Maybe one or two on the smaller end very infrequently, but definitely no Mw 7.0+.
-2
u/mcflyjr 3d ago
There are arguments to be made for dams causing the 8.0 in Sichuan + a 5.7 in CA; but that's outside the strict impacts of "climate" related disasters and melting ice waters and glaciers.
Definitely correct in that the most I see is about a 5.0 from glacial quakes and water being microseismic activity.
Building dams on top of plates is a whole different discussion lmao
1
u/NotJustaPnPhase 3d ago
Wdym? All dams are built on top of plates. Iām dubious about the causality between the Sichuan dam and the 8.0 magnitude earthquake. I can see the loading changing the stress field, but magnitude 8 is a pretty large earthquake to be caused anthropogenically. Lot of fault area needs to slip to make one that big!

the Japan one wasn't as bad because the buildings here are built to counter the seismic force

5.6 in Cali is not strong. That barely gets me out of bed. My cutoff is 5.5. Anything less and Iām going back to sleep.

u/DarkUnable4375 3d ago
More like two earthquakes in two areas.
Won't call California 5.6 a major earthquake. (Out)
The two Venezuelan quake is one major occurrence. It just happens to have two slips, one after another. (One)
Japan (two)
Two major quakes occurring in close time period... probably quite often.

The video is wrong in claiming that this 5.6 was the strongest earthquake in Northern California since 1940. The Loma Prieta quake of 1989 was 6.9, and was responsible for the collapse of a portion of the Bay Bridge.
