On top of that, one of the toughest part could be the extent of the power outage.
It's reported at around 46000 homes, the region has many elders and the outage will impact air conditionners, but also medical equipment they keep at home and supporting appliances.
Japan itself is involved with a lot of the R&D, the factories are there because of that and because of major buyers also being there. It’s not like we’re going to evacuate the hundred million plus of Japan.
This was my first real earthquake since moving to Kyushu. After it stopped I looked it up, and the first place to post the epicenter and shindo was NERV's twitter...which is named after the org from the anime and has an anime screenshot as its banner (https://x.com/EN_NERV). Apparently it's a real disaster information service, though.
It started as a Twitter account during the Tohoku 2011 earthquake, and then subsequently became a “real” service; the IP owners for the Eva agreed to let them use it going forward.
The Nerv app is quite good. It usually gives real-time alerts faster than the official sources.
You can even have the weird experience of being notified of an earthquake, watching the shockwave move outward from the epicenter, and feeling it as it passes.
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.
The second floor of the mall exploded for some reason, and the roof collapse is secondary to that. It seems to have happened after the earthquake and subsequent evacuation. There are videos of people leaving the mall:
And ironically in their press release for the re-open they said they re-built it with more disaster-proofing with the knowledge from the previous disaster...
The emerging thing is that the earthquake caused a gas leak which later caused an explosion. Pipes will just go out of alignment during an earthquake, there isn’t a ton you can do to prevent that wholly.
My question is why upon calling in a gas leak, the mall was not immediately evacuated and cordoned off.
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.
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.
It's my understanding that small to medium sized cities (and rural areas) depopulating is going on now throughout almost all of Japan. One of the things that really surprised me recently is how low the cost of real estate is for an older, normal middle class home in some sparsely populated areas of Japan.
Apparently the declining population and younger people not wanting to live in their parents' rural countryside home is having a significant effect on property values.
I wouldn't let this get in the way of going there though. Kumamoto is a very nice prefecture to see. They will rebuild (again) and it'll continue to be a great place.
No I mean of course, I thought Kumamoto was very nice and I especially enjoyed visiting Mt Aso, I was lucky enough to see into the crater and hike around the peaks
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.
To be a bit more precise, the Nankai ("South Sea") Trough is a tectonic subduction zone to the south of Japan, roughly the entire length from Izu to Kyushu:
I've heard there's been a lot of redevelopment in Nagoya, in preparation for a possible future earthquake from the Nankai Trough.
Exactly one month ago, there was almost consecutive daily earthquakes in Kantō region. Always a good reminder the whole country lies on seismically active fault lines.
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
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
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.
Many emergency shelters have not had their building safety confirmed so parking lots are opened to allow people to sleep in their cars, as they are warned to avoid "economy-class syndrome" from sleeping in a tight space. https://news.web.nhk/newsweb/na/na-k10015189161000
One thing I've noticed is that people in Fukuoka have stayed calm. I haven't seen panic buying of food or emergency supplies despite being so close to the disaster area.
Not like earthquakes are unheard of in Taiwan or South Korea either.
Buildings are going to be more expensive (base isolation and an extra commie blocks worth of reinforced concrete), but given how expensive fab equipment is, that might not even matter all that much.
Earthquake isolation can be pretty amazing. Here’s a video of a data center during the big 2011 quake. The camera is attached to the outer wall so the point of reference makes the wrong side look like it’s shaking, but you can see the people walking without difficulty during some pretty heavy shaking. A fab will have even better stuff.
Wow, it's incredible how far civil engineering has come in the past 600 years. To think that we used to have bridges collapse all the time, and buildings crack and collapse, and now we have buildings that can withstand a whole earthquake.
“A whole earthquake” is a very funny way to phrase it when it comes to Japan. That building has withstood tens of smaller ones before that big one, they’re just _incredibly_ common here.
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.
Meanwhile here an 80 year old, completely unremarkable house is likely to get declared "historic" and you as the owner can't even change the windows without permission. Tearing it down would be virtually impossible.
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.
Yes, but the situation got a lot better and a lot worse...
Sadly there has been a bunch of pretty devastating earthquakes in recent years.
In particular in Kumamoto the one in 2016 (magnitude 6.5) was huge and many of the houses built at lower standard or not in great shape anymore got partially or totally wrecked. Right now the house that are left are relatively well built.
The bad news is, that still doesn't help as the cumulative damage can still bring them down, and they're still subject to landslides, water damage, and other second order disastrous events.
Which works great in earthquakes in my experience in Christchurch. Most homes in New Zealand are made of wood.
Christchurch had a 7.1 that was 40km away, that caused some damage (certainly the wooden house I was living in at the time was fine).
Christchurch then had a 6.2 which damaged many concrete and brick buildings because the epicentre was shallow and within the city (6.2 sounds small but if it is close then that really matters). Many house foundations were completely stuffed, but the wooden houses above were often relatively unscathed. I bought a damaged house cheaply with a broken ring foundation: "as-is" or uninsured or insurance payout are the keywords.
Christchurch had maybe 180000 homes, of which about 10,000 were ultimately demolished. But they mostly weren't demolished because the wooden home itself had failed. The majority of demolished homes were in red-zones beside the river or estuary, which the houses could have been repaired but the ground was not good and also future flood risk was the problem. The government, the city, and insurers worked together to remove a lot of homes that had other risks.
For a long time "live with earthquakes and build accordingly" meant "make it easy to rebuild", not "engineer the structures to withstand the earthquakes".
The regulations got hardened in 1991. Obviously there has been earthquakes forever, but the buildings were not built to withstand them. That's one of the reasons why Japanese do not buy old homes: they are not earthquake proof.
One of the reasons Japan uses wood for construction is that combined with their traditional building techniques it results in earthquake resistant buildings.
And you will hear of wars and rumors of wars. See that you are not alarmed, for this must take place, but the end is not yet. For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places. All these are but the beginning of the birth pains.
Hope everybody is staying safe in Japan but this will not be the last earthquake, there are many experts pointing this as the beginning with even bigger magnitude coming up.
I'd strongly caution against a Japan trip right now.
Why does this earthquake, of similar magnitude, get so much more attention compared to the recent Venezuelan earthquake last month that was 100x more devastating? There was no commentary on HN about it.
The few socialist papers that I've read make the claim that there is nothing to pay attention to, and that the event is "American Propaganda" to try and make Venezuela look weak. The government attempts to control and suppress videos of the event.
Following the event involves trying to see past the state's narrative and take in anything that trickles through. Combine this with the fact that it's likely far easier for most HN readers to send aid to, or know someone in, a friendly nation like Japan. You get the recipe for coverage of Venezuela being muted by comparison.
I live in an earthquake prone area and thought Japan was cutting edge in earthquake protection. Beyond the obvious concern for other human beings, I am interested in why there was so much damage from what I would have thought was still a relatively manageable size earthquake for them. I am here trying to learn a lesson that I would not expect to learn from Venezuelan infrastructure and earthquake response.
It is also the timing of building booms. Problems being exposed have triggered regulations and enforcement in Venezuela but that is relatively recent and much inventory was built decades before.
The speed of videos coming out was a little slower so it lost the HN attention span - but it was definitely a hot topic in many other news places - Reddit, X, etc...
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
HN is exaggerating to feel close to the action. It's childish.
There is a trench off of Tokyo that is likely to rupture in our lifetimes, and people who have other people to check on don't care about HN's disaster fantasies.
