- ac29 1y agoBy magnitude it would be the second largest on that list
- addaon 1y agoMultiple lists. On the list of strongest by magnitude, it would be in a three-way tie for 7th if there's no further revision to the magnitude estimate (which there usually is). It would be second by magnitude on the list of deadliest earthquakes, but thankfully due to location will not likely make that list.
- BalinKing 1y agoThe first list on that page is specifically for the deadliest earthquakes, and so it only includes earthquakes with 100,000+ fatalities. The ranking by magnitude is farther down (and according to that list, a magnitude of 8.8 would make it tied for sixth place).
- swader999 1y agoI think it has been revised to 8. Earth is going off today. Edit my mistake, 8.8 now!
- nsingh2 1y agoThe other way around it seems, on `07-29-2025 23:24:56 UTC` went from 8 to 8.7 [1] [1] Table on https://www.tsunami.gov/ https://www.tsunami.gov/
- adzm 1y agoLooks like it was just updated to 8.8?
- tjohns 1y agoUSGS still has it listed as magnitude 8.7. (Update: It was just revised upward to 8.8.) https://earthquake.usgs.gov/earthquakes/eventpage/us6000qw60/executive https://earthquake.usgs.gov/earthquakes/eventpage/us6000qw60...
- russellbeattie 1y agoFrom videos online so far, it seems the strength of the quake didn't translate to massive lateral movement. There seemed to be lots of intense P-wave wiggling and bumping rather than large S-wave swings back and forth. The big Japan quake was one of those, where you saw offices being slid back and forth and everything flying off shelves. Not sure what that means for the tsunami - but so far it seems less intense than the 8.8 would imply.
- rtpg 1y agoJapan uses a scale that measures the movement[0]. Of course depending on where you are the result changes, but it's a lot more usable for the practical "how much shaking will be involved here/was involved here".

- russellbeattie 1y agoHoly crap. That scale definitely makes it pretty clear what the effect of a quake is! Here's the highest level: Intensity: 7 Category: Brutal Description: Standing or moving is only possible by crawling. People may be thrown through the air.
- SubiculumCode 1y agoWow. The same region had a 9.0 in 1952
- burnt-resistor 1y agoThe 1960 Valdivia quake released about 1.5e23 J, or about 1000 hurricanes, or about 25% of the total energy of all earthquakes in the past 100 years.
