Quake Watch 2011

BHN

This is a broadband station. The reason the trace is sloped is because it is picking up some low frequency seisms which might be microseisms, or might even be the Earth Tide.

The springs are almost certainly interference. I suspect that Zebedee must be around somewhere.

Just looked at that here. ERM.II.00.BHN.2011.074

That is totally weird. I have never seen that before. Mind you I mormally only look at the Z channel. ERM.II.00.BHZ.2011.074

Looks like Zebedee and a bunch of friends.


Ah wait, this is in Japanese. Don't they read backwards like the Chinese and many others?



Slightly more sensitive version

That o/s Queensland is an odd one alright

We had a strange one on Monday too, near the Snares Islands, south of Stewart Island.
REF:3478203
LAT/LONG: -47.94, 167.12
UTC: 2011/3/13 16:4:7
NZDT: 2011/3/14 5:4:7
DEPTH: 27km
MAG: 2.638ML
LOCATION: NE of Broughton Island, , S of the South Island
Reported as Felt: No

Don't usually have them that far east of the Solander Trough/ Pusygeyr Trench.
The Snares don't seem to be volcanic, as the rock there is granite.
But interestingly they are not far from the Mahuika impact crater .

"The location of a possible impact has recently been discovered lying in 300 m depth of water on the continental shelf 250 km south of New Zealand at 48.3 S, 166.4 E (Abbott et al. 2003). The crater is 20 km in diameter and could have been produced by a comet 0.5-1.05 km in size travelling at a speed of 51 km s -~ (calculations based on Marcus et al. 2005). When it struck, it would have generated an earthquake with a magnitude of 8.2 on the Richter scale. The lack of sediment that normally settles over time from the ocean suggests that the crater is less than 1000 years old.
The comet has been named Mahuika after the Maori God of fire."

Now that would have caused some huge Tsunami

I wonder if we are going to get more quakes in unusual places after that Japan 9.0

Some numbers from Japan.
(from our Dominion Post newspaper so no link sorry)

2414 ~ confirmed death toll, but expected to rise to 10,000+
14 trillion yen ($NZ233billion) ~ estimated cost of the earthquake and tsunami by Credit Suisse
55,380 ~ homes destroyed by the tsunami
2 mllion ~ homes without power
1.4 million ~ homes with no running water
4 metres ~ distance Honshu (and perhaps the whole of Japan) moved east
20 metres ~ the distance the Pacific Plate moved west
16.5cm ~ the distance the earth moved off its axis, due to a redistribution of its mass
1.8 millionths of a second ~ cut off a day due to the earth spinning faster as a result of the planets redistribution of mass

here's to find an map with the 6.2 mnt fuji with the aftershocks round it....

Wow. Thank you. I do hope that I don't get Ermintrudes

I think the others may not know what we are smoking!! More into Florence myself. Anyway Dylan says that there is something wrong with the N channel. They are trying to extract Zebedee now..... Fortunately the E and Z channels appear to be OK. Of course he should never have tried to get out of the Z channel.

Edit: Investigating further I find that it got sick and apparently has not recovered.

Day 71 OK


Day 72 Took sick


Day 73 Thought it had recovered so got up again, but not feeling right.


Z and E also got sick at the same time, but they recovered OK.

Ummm... Thank you... That is not a site I would have thought of going to for any such data so I'll have to check it out.

Anyway, if you are referring to the map posted by Shuichi Inoue (and I'm guessing you are), that's not showing aftershocks. It's showing the strength of the "felt" shocks in regions around the quake, based upon the JMA "shindo" scale. This is why the dots closest to the epicentre are mainly in the 6 to 5 range (orange to yellow dots), mixed with some in the 4 range (ummm... light beige dots), while ones further away progressively go down 3, to 2, to shindo 1 (blue dots to grey dots to white dots).

Typically in Japan when they report a larger quake, they also announce the "shindo" that can be expected in various districts, cities or prefectures. It's just the way they do things there.

Best regards,

Mike

As soon as I saw those weird traces I was thinking it had to be a glitch, simply because (like you) I'd never seen or even read of anything like them before! Many thanks for checking back and finding when that seismo went sick. I had it up earlier today but I don't bother watching E or N channels because ( a ) they're sometimes misleading and ( b ) I like to watch several stations at once and it's easier just to watch the Z channel on each one.

I got that tip from TrueAmerican, to tell ya the truth.

Mike

I had the flu... I hope I didn't spread germs. It has gone sick again so I will have to leave it and go somewhere else.
Time for bed. Thank you

Currently the links page in my signature leads to a main page with various pages of it for Earthquake lists, volcano lists, webcams, seismos, gps etc all on different pages. So basically you could say the the links are grouped by subject.

I am considering, although it is much work, changing the format so that each country has it's own page, however little info there is, and there would then be a world page. The page for each country would have earthquake lists, seismos, etc for that country all on the one page. I just wanted an opinion from people as to whether that would be better than the current listing system which sort of grew from the ATS page. I don't think I can maintain both! It could even have an historical section on the bottom if it warrants it.

Here is a sample for Japan

Since replying might be one liners or considered off topic a u2u might be better.

This one was ON LAND, did anyone notice?

OHH this is the one that was near Mt Fuji

Go back a page or possibly two.

Much discussion of it.

Hi Everyone (Long time reader - New Member)

With all the heavy-duty EQ's happening around the planet. I found this small quake quite amusing.

If you go to the Nevada Seismic site:

www.seismo.unr.edu...

and scroll down the right hand column until you find this listing: 44.2 miles NE of Little_Skull_Mtn.-NV
it's a 2.0 quake. now click the map to Satellite and zoom in. You will see that the quake originates right along side of the taxiway/runway at Groom Lake (Area 51)

Just thought I'd post this for giggles.

Puterman, I know I can be a pain. But before I ask you to look at something, I want to say it's great what you're doing out here. If I had any good suggestions, I definately make a few. But I think you're already going above and beyond the call of duty. I can only assume you are doing this for the betterment of society.

I just need you to tell me that a certain signal is nothing and just some local noise. There's been a couple similiar ones. But I'll just get you to look at one and you assess it's origin. It's just I have it in my mind that it is fluid movement.

At about 23:13 UTC, there is a green, chubby squiggly bit. Is it a car in the park?

Without having a listen I could not say what it is exactly, but it is not an earthquake for sure.

I don't have time to listen to it right now, but I can pull the sound any time in the next 14 says or so if you are concerned. I think it is nothing, as you say noise / a car etc.

I was just going to post the last Fuji quake. Would this be an aftershock
or a whole new quake of its own?

Its too quit...PuterMan?

Hm...

Have to Quote myself here,they are filling in missing Quakes now on USGS and EMSC. Stupid Seismologist´s making me worry,grml...

Have you seen this Vid ?
"Jim Berkland Quake Series And March 19 Moon"

I have put this here as Robin mentioned this chap in his Arkansas thread ... from page 190.

Lets just hope his prediction is wring on this one.
