We experienced a lower 6 on the shindo scale [1], which is the strongest earthquake I’ve ever experienced. The Noto peninsula experienced 7 and upper 6 level shaking.

Fortunately we have had a stretch of unseasonably warm weather recently, and most of the snow has melted in the area. If an earthquake of this intensity were to coincide with a meter of snow accumulation on the roof (we had 150 cm on our roof this time last year), it could cause many buildings to collapse.

That being said, I have seen some images of collapsed buildings coming out of Ishikawa, and I expect there will be some deaths from this earthquake. The live feed that NHK aired in real-time during the earthquake showed what appeared to be buildings collapsing. [2]

Note if you do venture onto twitter in search of updates, beware of trolls posting footage from the 2011 great east japan earthquake and trying to pass it off as current. E.g. images of cars being carried away in a tsunami are not real.

Not good, it is looking like not just the nearby building but also multiple more distant buildings collapsing from the footage from the Suzu City Office (珠洲市役所) [1] if you look for the dust clouds. Also, do note the very obvious damage to the roof of the building just across the street.

Edit: OpenStreetMap link for the city office [2] and the camera appears to be facing north east. The nearby building collapsing looks to me to be the Saishoji (西勝寺), Buddhist temple, main building.

What is positive is that it's a public holiday in Japan and many larger buildings in the area would've been empty.

Larger buildings tend to better withstand the large quakes. Building codes have been revamped after large quakes in Japan, so large commercial and public buildings tend to be the safest ones. They also are used for temporary shelter in natural disasters like quakes and heavy rain/typhoons.

Problem are with older wooden houses. There's quite a few photos and videos of older houses that have completely collapsed or their ground floors collapsing.

On a side note, since it's a public holiday, hospitals aren't able to cope with those who are injured because they're lightly staffed, and medical personnel can't reach them due to damaged roads, etc.

Indeed. For those who do not know, new year celebrations in Japan happen from 1 January onwards [1] and usually entails visiting in-laws, parents, and grandparents (or them visiting you), very much akin to Christmas. Thus it may very well be more likely to have families coming over to their parents and grandparents living in older houses on a day like this than any other time of the year.

They've been revamped, but Ishikawa hasn't rebuilt everything to the new codes in the last 40 years or so they were introduced.

It's not a wealthy area.

There are ways to upgrade existing buildings that makes more sense in taller buildings than small houses, which of course is government subsidized, so taller buildings in Japan are often safer. Or at least safe for the first one. Some says the exoskeleton approach[1] is ugly as hell, I think it's cyberpunk.

I have never seen any of this in Joetsu or surrounding areas (very close to Ishikawa). Maybe you've spent most of your time in Tokyo?

It’s a fairly common sight in Joetsu, particularly for government buildings. This company shows a list of seismic retrofitting projects that it has done in Joetsu, for example:

There are also subsidies and financing available in Niigata prefecture for seismic retrofitting wooden homes built before 1981:

For sure though there are many homes in the area that have never been retrofitted.
