there was also a 2.1 a bit further north at Wairakei, at the Craters of the Moon geothermal area, very shallow

here it is on the deep quakes for Waikato, theres a little red one under it to the right, which was a 2.9ML on the 10th March UTC, 99km deep

A forboding perhaps, when was that big quake prediction again, 19th-20th was that UTC ?

Hmm... West coast is now waking up it seems. I would rather it doesn't with all the hub bub of the ring of fire threads.

Well I don't know if this helps anyone or not but I have just spent some time doing cumulative graphs (the ones I often display here) for every area I can think off.

This is done by name so things like Alaska, Kamchatka, Oregon, Washington, Arkansas, Greece, Crete, Ionian, Iran etc Anyway, a very long list!

With the exceptions of Japan and Arkansas every single region input is rock steady with no sudden twists in the cumulative.

I lost count but it was over 60 graphs so i won't upload them!!!!!

Basically what I am saying is that despite what the popular theory may be, all is pretty much normal except those two areas.

4.6 Alaska right now?

You have been busy! Thanks for doing that. It shoud put some minds at ease.
I think your idea of separate web pages per country is a great idea. If I knew anything about it I'd offer my help. Perhaps you could eventually put these plots up on there for areas of concern?

Just a little one out in my part of the world.

is this normal or unrest?

Don't know if this indicates that the pacific plate is still moving but last I looked there was indication that it was moving south... And now this earthquake 6.2.. Would say that some stress did build up over there.

You might need to re-post this every few posts - the forum seems to have been going NUTS with people repeatedly posting threads over every little EQ.

Even our news just this morning (or last night) said 'This is a story just breaking - there has been a 5.3 in Chile - no reports of casualties' Really? Breaking? 5.3?

Not feeling too normal here, Puterman

My sincere apologies, New Zealand is of course another exclusion. Because the data that I get from GeoNet does not have locations I am not able to run a cumulative yet so I did not do that one, but yes that should be an exclusion as well.

Edit to add: The graph below shows the current activity in NZ in the eyes, in effect, of the USGS. It is quite obvious that this is not the case.



I am going to re-write that part of my program so I can use a different parameter to get a correct graph.

I have managed to extract one using Latitude and Longitude however I cannot guarantee the accuracy as there are overlaps. I offer them as is. Also these are only from 1st Jan this year.

North Island


South Island


Bear in mind also that these are only earthquake numbers. Another change to the program is going to have to be cumulative energy release.

reply to post by Wolfcomplex


Above average. The 'normal' magnitudes are around 4 to 5.

The problem is that you will never see anything lower than 4 on USGS for that area so you have no idea what else might be happening. Having said that it is possibly very slightly over the normal but not by much.

I know you all dont like posting small quakes but this is in an unusual place isnt it?

Hi kennylee. Yes we clocked that one.

www.abovetopsecret.com...

I am thinking fracking/water injection or something but I could well be way off base on that.

reply to post by PuterMan


I should have went back a page. Sorry about that. Just shows how slow the quakes get posted to me.

Are there injection wells in the area that you know of?

The Youngstown, Ohio earthquake finally showed up on the big list. I doubt it is due to fracking. Funny thing is there is a Natural gas company with their offices on Salt Springs Road. There are coal seams in Youngstown. Could be an old mine shaft collapse. And you are right about the salt. Just north of the quake is salt production.

How do you get salt out of the gound? You inject water and suck up the brine.

The China earthquake was very peculiar. I think it's due to irrigation. Find the epicenter and you find an oasis.
I guess I'm wierd. Most of you are interested in the Ring of Fire. Others are interested in the paricular faults where they live. My heart still skips a beat when I think about you Kiwis. But I'm always swimming upstream.

I guess it's because the Ring of Fire is always active. I watch the plates crashing everyday. I know new people that are tuning in because of Japan see an alarming mass of coloured markers all over the maps. I understand this reaction. But it's all very normal. I'm surprised that the Japanese say they're surprised by the size of the main shock. Really? Banda Aceh. Alaska. Chile. Why would Japan be any different? All of the earthquakes are from completely understandable tectonic forces. Yes, you can speculate on triggers. Moon, solar storms, etc. But no one should be really surprised by the event. Exclude nuke issue. I'll swear if I don't.

Of course, I am very interested in the dynamics of large earthquakes. And I want to have people understand the dangers so they are prepared. But I'm fixated on the mid-continental quakes. Very little is known about these seemingly random occurances. The San Andres fault is probably the most studied of all. The Indonesian Earthquake was extensively scrutinized. I followed the scientists as they discovered the great length of the rupture and the surprising extent of it's thrust and movement. I think most of you are aware the entire island of Japan just jumped several meters toward the United States. All of this fascinates me and keeps me gripped with curiousity and wonder.

I'm not just curious about mid-continental earthquakes. I am preplexed and stupified. And in the end, I'm alarmed.

There is much more going on than known tetonic forces. There is an artifical element to the activity. Research artifically induced earthquakes and you will see the future trend. Forget which way a particular fault may be trending. Well, not entirely, that's important. Concentrate on the trend of mid-continental earthquakes.

We are drilling for oil. We are drilling, and fracking for natural gas. This process sometimes includes injection wells for disposal. We drill for water. We drill and mine salt. Coal. Potash. Minerals...

That's a whole lot of human activity deep within our earth's crust. And that activity is changing the equation.

Why the hell would someone let the natural gas boys frack and inject in Arkansas right near a known active seismic area? I know the answer, it was rhetorical. There have been swarms in Enola. I think Enola was artifically induced. The evidence points to fluid induced siesmicity. But no one claims to know the specific source. Could be from the hot springs not far away? Or it could be from human activity.

I now believe that the Arkansas earthquakes are not an old fault reactivated by injection. I believe the injection created a fault where there was none before.

The major salt mines in this area are under Lake Erie. Morton Salt has a huge operation here, about 3 miles from where I live. I have not once in all my years living in this area felt anything related to those mines.

Like I said, watch the trend, you may be feeling them in the future.

Here's a map of recent quakes in Southern Ontario. You'll notice the relationship to Windsor Ontario. Major salt production area.
On the map, you'll also see the Ohio quake. It showed up on Canadian maps before the US.

I've been to the salt mines in Salzburg, Germany and they are massive. Also I have been to the Mortan plant in The Great Salt Flats here in the U.S. These are two totally different styles of salt mining but both are very much different from fracking of drilling. I'm not sure I understand where you are going with your thoughts please explain.

In both areas water is not "Injected". Yes using water to dissolve is part of the process but as for pressurized injection I've never heard that this is the case.
