Japan hit by 8.9 Magnitude Quake, Tsunami Warnings In Effect

Re: Japan hit by 8.9 Magnitude Quake, Tsunami Warnings In Effect

So the radio says the west coast has a tsunami watch, but the papers says we don't. I'm assuming that being in Silicon Valley I'm out of any tsunami's reach though. AJE (http://english.aljazeera.net/watch_now/) has some good coverage, the footage of the wave of water and rubble slowing advancing over the land is amazing in a scary way.

Currently sitting inland of Santa Barbara about 3 miles. Have a friend at UCSB 2 blocks from the ocean. The entire state has a Tsunami Warning, and we're keeping an eye on things.

My vacation started today, and there's a Tsunami Warning. Kind of unsettling....

Expected to hit Hawaii at 8 am Eastern Time, 10 AM or so for the west coast. Not sure what its going to be like when it gets to Hawaii. Reports were put out over the concern that the Tsunami was larger than some of the smaller Pacific Islands.

8.9:eek::eek::eek::eek: That's enormous. Richter is a log scale, which means that the strength of this one is about 10 times a 7.9, which is pretty huge in itself. According to Wikipedia, there's about one 8.0 - 8.9 a year, but I can't remember ever remember hearing of one that large.

The one in Chile last year was 8.8

And roughly 100 times as strong as the one that hit Haiti. Of course Japan will rebuild a whole lot faster.

Amazing that a wall of water 6 feet high can travel at the speeds faster than a jet liner, wow, Hawaii is gonna get whacked. Sounds like low lying areas have been evacuated already, only a few more minutes before impact. I guess Hawaii has quite a warning system because of past issues, sonar buoys placed all around the pacific will give them some idea how bad before it hits, if that helps

Earth crust displacement... 2012!!!
 
Re: Japan hit by 8.9 Magnitude Quake, Tsunami Warnings In Effect

Actually, as of 7:30 EST, NPR had already spoken to people in Guam and Saipan. They said that the tsunami had already passed with no ill effects. Slightly larger waves, but no damage at all.

They also said that the Sumatra earthquake took place over a 900 mile long fault line. Therefore there was a lot more energy released and that that caused the huge tsunami. This earthquake, while larger on the Richter scale, was very localized. They're really not expecting anything like the tsunami in Sumatra. That said, they also noted that the airport runway in Sendai, the nearest city to the epicenter, was underwater.
 
Re: Japan hit by 8.9 Magnitude Quake, Tsunami Warnings In Effect

As usual the Board comes to the rescue with all sorts of info that I didn't know about magnitude and tsunami. The footage is amazing! Prayers for all those affected. this is going to be a helluva clean up

Why did the navy order ships to stay in Pearl Harbor? Wouldn't it make more sense to get ships offshore in the deeper water?

Tsuamni relief perhaps?

Perhaps Pearl Harbor wouldn't get as big of waves as the open ocean?
 
Re: Japan hit by 8.9 Magnitude Quake, Tsunami Warnings In Effect

Sounds like Hawaii has been hit in places and not much has happened,

Pearl Harbor has been hit, insignificant according to the Navy, good news for them

Probably because they couldn't get them all out in time, and if one got stuck at the mouth of the harbor it'd be worse.

That's good news. Should be weaker by the time it gets to Cali as well then?

From what little I remember from my "natural disasters" course in college (easy science credit FTW), the distance from the epicenter doesn't affect it all that much, or at least not as much as you'd expect. The fact that Guam and Hawaii didn't see much at all would seem to make it more likely that it was simply a focused tsunami, and thankfully for the U.S., it was directed towards Japan rather than across the Pacific towards us.

Interesting. Thanks.
