Magnitude 9.1, actually.
- irchans 4y agoThank you! Huge difference! Lack of research on my part. Sorry
- midoridensha 4y agoActually, it was a Mw 9.0 according to JMA.
- moloch-hai 4y agoThis makes no sense. Earthquakes in different places can be compared only on a common scale.
- delroth 4y agoLooks like JMA says 9.0, USGS says 9.1. I don't really have enough expertise to know which number is more accurate, and I suspect it doesn't make a huge difference. It's in any case the highest magnitude earthquake ever recorded in Japan.
- midoridensha 4y agoJapan gets earthquakes every day, and is much more seismically active than the US, so I would favor their expertise more. But yeah, it was the highest ever recorded. According to Wikipedia, it actually moved Honshu (the main island of Japan) by over 2 meters to the east!
