When I first saw the headline that it occurred in Russia, I assumed the U.S. dropped a nuke on them.

Powerful quake in Russia's Far East causes tsunami, Japan and Hawaii order evacuations

Several people were injured in the remote Russian region, while much of Japan's eastern seaboard - devastated by a powerful earthquake and tsunami in 2011 - was ordered to evacuate. "Today's earthquake was serious and the strongest in decades of tremors," Kamchatka Governor Vladimir Solodov...

(Reuters) -A magnitude 8.8 earthquake struck off Russia's Far Eastern Kamchatka Peninsula on Wednesday, generating a tsunami of up to 4 metres (13 feet), damaging buildings and prompting warnings and evacuations that stretched across the Pacific Ocean.

Thank you for this, steeltowngirl!
The geologist in me is very interested!
Wish I could understand Japanese!

They had a similar one in 1952, that one was 8.0 and closer to the shore. This time it was 8.7 in the epicenter (in the ocean).

The largest earthquake recorded was 9.5 per Richter scale in Biobio, Chile in 1960.

Yes, but I read that it was shallow (12 miles deep). I lived through the 1989 Loma Prieta quake. Here is the difference between them Hard to wrap your heads around it!

It should be pretty accurate as that tool is on the USGS site: "How Much Bigger…?" Calculator

not to be pedantic, but 8.8 now!

Upgraded to 8.8

A massive magnitude 8.8 earthquake struck off the coast of Russia Tuesday, sparking tsunami warnings in Alaska and Hawaii and alerts for other areas of the West Coast.

The earthquake occurred about 85 miles off the east coast of Russia's Kamchatka Peninsula with a depth of nearly 12 miles, according to the U.S. Geological Survey. The agency upgraded the earthquake's reported magnitude from initial reports of 8.0 and 8.7.

Tsunami alerts were issued for Alaska and Hawaii on Tuesday after a major, 8.8 magnitude earthquake struck off the coast of Russia, according to officials.

What little video they have in this clip it's not looking as bad as I thought. I mean, it's BAD, but I remember what the 1989 quake looked like upfront in my face.

Yeah, I wish MSM would STOP rounding it down to 8.0!!! Drives me nuts!

Shallow depth means it may be less likely to bring as much damage, right? I ran over to check the depth of the 2011 tsunami in Japan. Appears to have been about 15 miles (25 km) depth.

Looks like it's moving down the fault line. That blue dot is actually orange (Day). I had it selected to look at info which turns it blue.

I’m reading the earthquake wasn't a pure thrust and likely had a lot of horizontal movement, hence the relatively small tsunami heights — praying it stays that way!!

This'll have to be JMO as I heard it on Bloomberg news. I like watching Asian news in the evening. This isn't too bad. I don't think a foot wave can do much damage but I can't be totally sure of that. I guess it depends on the force and other factors.

largest waves seen are 30 centimeters (~1')

No, shallow depths are worse than deeper depths. Just exaggerating here... but a 1' depth is way worse than if it's miles deep.

Shallow quakes generally tend to be more damaging than deeper quakes. Seismic waves from deep quakes have to travel farther to the surface, losing energy along the way. Shaking is more intense from quakes that hit close to the surface like setting off "a bomb directly under a city," said Susan Hough, a USGS seismologist.

How shallow, deep earthquakes differ

Italy's earthquake was a lot weaker than the one in Myanmar, but it did far more damage because it happened at a shallower depth. The Associated Press explains the difference between shallow and deep earthquakes.

Me too about wishing I could understand Japanese. They don't seem to be overly excited and there were cars still on that bridge so maybe it's not going to hit too hard.

I'm an hour inland, and we received a county-wide Tsunami alert on our phones. It's expected to hit the West Coast around 12:30am PST.

This site is saying up to 3 meters expected in Japan. Idk how accurate it is.

In Hawaii? Or California?
