In parts of Kumamoto Prefecture, it registered 7 on the Japanese shindo (seismic intensity) scale, which reflects the amount of ground shaking at a particular location. The shindo is a better indicator of the likely amount of damage than the magnitude is. A shindo of 7 is extremely strong [1].
Ten minutes ago (at around 17:15 p.m. Japan time), NHK was reporting that there were many emergency calls coming in from Uki City, where shindo 7 was recorded, but that the extent of the damage or injuries was not yet known.
There have also been many aftershocks, including some strong ones, and tsunami warnings.
NHK TV is showing extensive damage including fallen smokestacks at Nippon Paper Factory facility, bridge road separation, fallen bridge lane, road cracks, fire, water coming out of drainage etc. It was a huge earthquake and will take some time to assess the damage.
Kumamoto is barely finished rebuilding from the last quake, you can still see cracks in structures as you drive down the road. This is really horrible; not to mention the city is already beginning to depopulate as the youth move north to Fukuoka.
I'm living in the South of Japan, it was a 4 intensity where I am (about 90km) from the epicenter. Luckily there was only some light shaking and nothing fell over here.
I hope everyone is safe in Kumamoto.
In my area, we have been repeatedly warned that a major earthquake called the Nankai Trough is likely to occur in the last few years or decades, so I am very scared of big earthquakes happening in other areas as well.
I was camping/bike packing in Kyushu when this happened! I think I was in Miyazaki on the 14th when we felt the first shock. It was the first earthquake I’d experienced. The multi-story hotel we stayed at felt like it was gyrating in a circular fashion.
Then my pal and I were camping by the Utagenka Bridge, east of Kumamoto for the main shock!
Fukuoka here (about 100km from Kumamoto) and definitely felt it, so it must have been a real big one in Kumamoto itself.
My friend was driving home from work closer to Miyazaki and didn't feel the quake, but had huge hailstones hitting his car. There's a rapture going on or something
Given it’s barely even felt outside of Kyushu (JMA 3, the dark blue dots, is "dishes may rattle, some people walking outside notice") that seems unlikely.
Every once in a while (not every year) there are minor earthquakes you can feel in some parts of SK, like Busan: the ground tremors a bit, some shelves wobble... that's the most I've ever noticed.
Found a few online webcams, but I'm not really sure I saw the earthquake. People didn't even seem to stop on the webcam I was watching. Lots of cars on the bridge afterwards though while before it there were much less, idk
There's plenty of old buildings here that are not built up to the latest standards; increasing exponentially the further you get from the core of a big city.
Japan is _very good_ at tearing down old buildings and building better in their place; but it doesn't mean that there are zero old buildings around.
They could have been further away from the epicenter of the previous ones, or the previous ones weren't strong enough to cause that specific structure to collapse, the previous ones might have weakened the structure and this one brought it down, a million different things factor into this.
Earthquakes aren't a perfectly repeatable occurrences you can run a regression test against.
Like half of the buildings are non-resistant since they are old and made of wood. IIRC only buildings built after 1991 are guaranteed to be earthquake resistant.
One of the reasons Japan uses wood for construction is that combined with their traditional building techniques it results in earthquake resistant buildings.
For a long time "live with earthquakes and build accordingly" meant "make it easy to rebuild", not "engineer the structures to withstand the earthquakes".
Haven't seen anything on the Tsunami global warning list so hopefully it's okay. Earthquake looks centered on land which (to my unofficial understanding) means low risk of Tsunami but of course higher chance of direct damage

Hope the areas around you were just as lucky, thanks for the update!

Similar strength and location as the 2016 one: https://en.wikipedia.org/wiki/2016_Kumamoto_earthquakes

Does anyone know if this also affects South Korea?

Dishes may rattle feels like such a japanese way to describe it

Never felt anything in SK
Thank you for this update.
I was told that some people in Busan, the Korean city nearest to Japan, felt the earthquake and even felt dizzy.
I'm in Busan, though I didn't feel anything. (I was on the beach at the time though.)
Was looking at webcams here (https://tokyo.fyi) but realized this is further south.

Some of the webcams are fake fwiw, I noticed a while ago when there were ads emblassened with old dates on them.
Edit: to be clear, this was random ones on YouTube, not sure about that site.
arent they trying to make silicon fabs there?

7.1 seems to mean non resistant buildings may collapse.
Yea seems pretty bad given its on the higher end of the scale... I might be naive but I hope nobody died
https://en.wikipedia.org/wiki/2016_Kumamoto_earthquakes
The main shock of this one at 7.0 killed 277 people so sadly I think it’s pretty likely there will be some deaths.
It's Japan though. They don't have non-resistant buildings.

Wouldn't the not so strong old buildings have collapsed during previous quakes?
Possibly, and then rebuilt. They rebuild houses every 20, 30 odd years anyway (according to https://www.theguardian.com/cities/2017/nov/16/japan-reusabl...), and temples too https://longnow.org/ideas/long-term-building-in-japan/.
They could have been further away from the epicenter of the previous ones, or the previous ones weren't strong enough to cause that specific structure to collapse, the previous ones might have weakened the structure and this one brought it down, a million different things factor into this.

Earthquakes didn't start in 1991. The Japanese have always had to live with earthquakes and build accordingly.
For a long time "live with earthquakes and build accordingly" meant "make it easy to rebuild", not "engineer the structures to withstand the earthquakes".
In Gölcük/İzmit, there was a huge 7.4 earthquake in 99.
https://en.wikipedia.org/wiki/1999_%C4%B0zmit_earthquake
It took around 10 years until the city felt "normal" again (source: a close friend lives there).
My point is, it's never easy to rebuild.
Shit hope everyone is ok.
Tldr; Seems like major cities didn't get hit by the earthquake at 7 scale.
Hoping for zero casualities.
Apparently there is a risk for tsunami so Japanese govt has issued a further alert. Hope it isn't anything too bad either
