The power of Japanese engineering is no joke. In 2011, my father, sister, grandparents, and I lived on the 9th floor of a Japanese apartment building. From our location, the shock was approximately equivalent to a 6.1 magnitude earthquake. Despite this, only one item broke in our house, some unimportant, glass object. No one from our floor was hurt, none of our standing cabinets or dressers had fallen over, and everything that had fallen was easily repositioned. That was the only earthquake that made me feel scared while I lived there. I’m truly grateful for the work these people do to mitigate future disasters.

A few errors:
- confusion between seismograph (the instrument) and seismogram (the recording)
- on the magnitude scale, it's not an increase of 1 that represents 10x of the energy of the earthquake. It's actually an increase of 2 on the scale that represents an increase of 1000x of the energy (so an increase of 1 is ~30x)

I worked for 41 years at a testing lab. We owned and operated two earthquake simulators. One with a 10 x 10 foot table and one with a 20 x 20 foot table. The heaviest specimen I ever remembered testing was a 12 cylinder diesel generator, use for emergency power for hospitals in earthquake zones. The generator weighted 65,000 pounds. I've got to witness hundreds of earthquake tests through the years. I'm now retired but was very lucky to have had such a enjoyable and rewarding career.

Jan 1 2024 a 7.6 (on the Japanese seismic intensity scale) earthquake hits Noto Peninsula of Ishikawa.
Just 150 KM from where it was predicted by semiologists, and reported by the Veritasium team in this video, uploaded 13 days ago.
Mind blowing how accurate this was.
So far only 1 reported fatality (due to building collapse)

I love the quickness and implied obviousness of his response to "how do you predict the earthquakes" with "ask the seismologists", because even though he is an expert in simulating and testing earthquakes, studying how they happen is an entirely different area of professional experience. That's a sure sign that someone is truly intelligent, no speculation, no half-assed answer based on something he sort of knows about, just "ask the experts of course!"

The timing of this video is crazy. My thoughts to the people affected by the new years 7.5 earthquake.
