7.8 Quake Just hit Japan- southern islands- Reduced from 8.5

I wanted to see what this looked like here PA.
The closest seismo that I've found to me is about 35 miles away.
When I pulled it up it was blank!
Looks like it's been down since a little after 8 AM Friday!
Weird though, the 6.7 near Alaska isn't showing!
The 6's in the Solomon's showed up nicely though,
sure wish it would have been working!

It's happened a few times before that I happened to notice.
It's somewhere on the college campus & now that it's a weekend,
probably won't get noticed 'til at least Monday!
If this is finals week coming up....probably not then either!!!

do you mean this one, or do you know of this one?

According to wiki this is the deepest, deep focus earthquake ever recorded .

The strongest deep-focus earthquake in seismic record was the 2013 Okhotsk Sea earthquake (magnitude 8.3) that occurred with an epicenter in the Sea of Okhotsk at a depth of 609 km.[5] The deepest ever recorded earthquake is the 1994 Bolivia earthquake with a focal depth of 647 km and a moment magnitude of 8.2.[3]

Basically yes, that's right.

It's because the energy released radiates out in all directions (though it may be more concentrated along some axes), so the deeper it is, the greater volume of crust there is to help to dissipate it.

My lampshade rattled a bit. My cat hid under the bed.

At first, I didn't think it actually was an earthquake. 'Huge' is a bit of an exaggeration.

a reply to: JustMike

So there's percentage chance that sub sea quakes are happening. And not all sub sea quakes are a threat.
Then the conditions have to be optimal for tsunamis to happen.


Thanks for the explanation that makes it clear..

I don't care what anyone says, the quakes in the pacific rim are getting stronger

I can also confirm.

I think there has been about 3 so far (i'm seeing a 4.8 on my map)

A biggie, but very, very deep. Better to be super-deep than shallow, KWIM?

It would be a data venture for our EQ guys to translate into a people-friendly graph/chart, but I'd say that claim would
only be applicable if the energy output backs up your speculation there.
Muzzy puts together some awesome charts, you should consider asking him if has the spare time to create one for the PR.

Hmm, I am looking at the 13km depth (pretty shallow) of that 6.4, as well as the distance of over 300 km from the epicenter of the 7.8. And that 6.4's on the other side of the subduction line. It possibly suggests a wider area was, or will be, affected. All bets off on Japan. Anything can happen.

a reply to: TrueAmerican
It's certainly of concern. That mag 6.4 is no small event and as you say, it's very shallow. Those two factors alone would ring a few alarm bells but considering proximity to the mag 7.8 there might be something else coming along, possible N / NNW from the 6.4 along that same fault line.

Near one of those two triple junctions, for example.

Way too deep to be of any real concern. Lucky for them. Interesting though because there have been quite a few deep earthquakes that say something is going on deep, deep, below us.

a reply to: curiousme333

Godzilla is or some MUTO is digging it's way out of earth.

a reply to: JustMike

Yeah, could be trouble ahead. In looking at the last 30 days at USGS:


Look at the lack of quakes in that hole in the red circle I drew. Southern Tokyo had better watch out.

Plus, I put a red star where I believe after some research I did that a major quake may be due because that spot hasn't had one in recorded history. I have a thread on it around here somewhere. And that would be rough, because a large enough one right there would send a tsunami straight into Tokyo Bay. Which, by the way, because it is a bay, would concentrate the wave and cause it to be even bigger. As in like up to 150 feet in places. Seriously I think you gotta be nuts to live in Japan. If the tsunamis or quakes don't get you, the volcanoes will.

Crazy times indeed....

The people are turbulent enough without nature throwing in her 2 cents......

This one?

When you take notice, I take notice.

a reply to: jadedANDcynical

Wow, I see that thread now and it sure brings back memories. That southern boundary looked almost sure to give way in the face of catastrophic seismicity headed its way and all around it after that 9.0. But, it didn't. At least, not yet...

Nice try J&C, but no, that's not the thread. This is the one I was talking about:
