Quake Watch 2011

Not showing up on USGS yet, maybe it will maybe it won't. We did get more rain today but this is showing up on most stations in the state and the rain and thunderheads have gone.

For weeks now since Japan had the biggy 9m I have been checking the daily activity. That being said I find it very very odd that there has been no activity in Japan at all for close to 24 hours now. No after shocks, no bumps, nothing at all since the 6.4m one.

Anyone else notice or care.

You are not going to get too many Mag 5's out of a 6.5, IMO maybe in another 24hrs there might be one or two high 4/ low 5's that usgs might consider listing. That seems the general pattern.


FYI that 2nd list is the one to watch if you are seriously watching Japan. Click on the top one on the list and it goes to a map with lat/long, then you can click on "previous" and go back through the list one by one.
I still haven't found a long period list source off JMA, so you have to download at least once every 7 days to keep a database.

Sorry but why is that odd?

It was never a very seismic area off the East Coast of Honshu. Could it just be that things are settling back to normal after the 'big one'

Why does it 'going quiet' mean that there is impending doom? (@berkeleygal)

Aside from that however as muzzy says there are quakes BUT I do take your point as nothing is showing on EMSC or USGS since that 6.4 so you are not wrong in your observations. I guess it is the weekend maybe? Does sem a little odd that EMSC has not registered anything as they go lower down the scale than USGS.



If you go to this page you can see all the seismograms around Japan for today and yesterday. Most of them for today UTC do seem quiet, and the list that muzzy produced does fall into yesterday UTC mostly.

I guess it is just quiet!

Have a look at it on the ISIS webicorder version. Looks much more impressive! FCAR.AG.00.HHZ.2011.205

It does not seem to have turned up yet. I would put it around 2.x I guess depending on how far that recorder was from it.

It is the week end so I guess no one is in a hurry

Don't know how that relates timewise. (Why can't everyone use UTC ) but I would have said that was well clear of 02:17 UTC since that update time is around 11:00 UTC I think.

Surprised I didn't feel this, must have just gone to sleep

I had a play with this page and ended up downloading a month of data using WinZip (on old Desktop) and it took about 15 minutes
Too much info
Any ideas how to filter it?
or how to copy and paste that list of results inside the 'Earthquake List" window?

Also noted the last quake was the 6.5, so its not much use if you want all Japans quakes.
Looks like JMA does the best job.

This area is so predictable. Scary..another 6.2..just wow.

for a change the JMA has the same magniutude

Christchurch is 'quiet' at the moment which is good as there is a heap of snow here. Nearly 30 cm at our place....no work today!

reply to post by muzzy


As you are possibly aware by now I have cracked screen scraping the JMO website. It is quite intensive as it has to down load a datafile for each quake in the list to get the lat and lon.

I sent you a CSV of the data.

so by my calculations
thats 6 x MAG 6+ E/Qs in the last seven days...


normally 2-3 per week...

Something of un-noticed, little reported but serious potential.
4 days, 500+ small quakes swarm, depths from 5km to 15 km.


The Canary Islands Government has said it is monitoring an earthquake swarm on the small island of El Hierro where in excess of 400 tremors of low magnitude have been recorded in the past four days.
