Tsunami Warning for Hawaii after 8.7M earthquake hits Russia; evacuation zones in place

[Charlot123]

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

Yes, because the Richter magnitude scale is logarithmic.

A lot depends on the area, too. The Spitak earthquake of December 7, 1988, was about 6.9, but it was in densely populated mountainous area so the amount of deaths was close to 25000. The Mexico earthquake of 1985 claimed over 5000 lives.

It's paywalled. I'm slightly concerned, but not very.

 

[browneyes]

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.

Stay safe @LinasK .

In Hawaii? Or California?

Technically, could be all of it. Too many faults.

My favorite one at Taipei 101. A mass damper that prevents the high tower from swaying during earthquakes.

I’m on the central coast of California and got the emergency text notification, four hours ago. Also set to hit at 12:30 AM.

ETA - local news just said it has been downgraded to an advisory.

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.

The 1964 Great Alaskan Earthquake was a 9.2.
It is my favorite earthquake; sorry if that’s weird.
National Geographic had a whole issue about it back then. My Dad had years and years and years of National Geographics that my sister and I donated to our local library after his death. Except the 1964 issue about the Alaskan earthquake. I still have it. Couldn’t give that away!

Supposed to hit Hawaii about 10 minutes from right now.

And the west coast at these times:

Keep us updated on what happens in Hawaii. We have at least an hour 1/2 before we know what happens on the West Coast. Just turned on the 10:00 news.

Interesting.

Hawaii-bound that are more than half-way there are all being diverted into Honolulu. The last few flights into Kauai, Maui, and Kailua-Kona are now beginning descent for arrival and all subsequent flights are going into Honolulu.

 

[Sarahlou]

I hope this doesn't turn out to be a bad as it sounds and that everyone in the affected areas stays safe.

 

[LinasK]

A California woman called into the local news from Kauai. They are expecting the waves to hit in a few minutes. Everyone was evacuated.

Lilibet, do you need to worry in Ashland?
