Here is a “live view” of the same place so you can watch anything “new” that develops:
Southern South America Hemispheric View
South America with “clickable” areas for more details.
So we had a boat load of big ones in the area around Tonga, Indonesia, and even some up toward Japan. Now it’s rocked back over to South America. I feel like I’m sitting in a shooting gallery and folks are getting hit all around me, and I’m not, and it’s only a matter of time… But I’m glad I’ve not had a ‘big one’ redux… Yet…
Here’s the whole Asia view:

So both those areas have ‘cooled off’ for a bit. Who’s turn next I wonder (as he whistles in the rain…)
The Rest of the World Earthquakes
Here is a Pacific centric view:
With quite a bit of action North of New Zealand and Australia. It looks like it’s ‘cooled off’ to 5.x range aftershocks.

Both Hemispheres
Last time I’d noted:
Looks like in / near Chile there is another set of two 5.x quakes, though a bit further apart than a ‘pair’.
Those now look like ‘foreshocks’. Why I watch where the 5.x size are happening…

Action Closer to Me
As I live in California, it makes it easier for me if I keep them in the list where I can see what’s shaking near me.

Two 3.x off the coast near Eureka and a pair of 3.x bracketting Lake Tahoe. Very strange. The number of 3-ish quakes is quite large, especially the number of quakes down in the L.A. Basin and even up to Santa Clarita. It’s just a jello bowl right now.
Mammoth Lakes / Long Valley Volcano
Because I want to know if it starts to blow it’s top…
Mammoth Mountain - Long Valley Super Volcano
And now we can see that the lower 3.x “near” lake Tahoe is more or less on the fault system that runs through Long Valley Caldera / Mammoth Mountain and on down to Baja. It’s got action, though small action, on both sides of the place I definitely do NOT want to see any action… Sigh. I think it’s going to be a long decade…
Musings from the Chiefio 
What is worrying is that the earthquake in Chile has happened in the same area as the 8.9 Richter February 24, 2010, at Concepcion, Chile
Correlation?:
http://www.vukcevic.talktalk.net/LFC13.htm
Strong earthquake affected regions VIII and IX and cause fear in people
The President Sebastián Piñera Onemi reached where dismissed the danger of a tsunami.
A strong earthquake of 6.9 magnitude on the Richter scale, struck at 17.20 on the shores of the regions of Bío Bío, Araucanía and Los Lagos, sowing fear among the population.
The epicenter was beneath the sea, about 149 kilometers west of Tirúa, Region IX, at a depth of 16.9 kilometers. Meanwhile, the measurements made by the National Oceanic and Atmospheric Administration (NOAA) indicated that an intensity of 7.2 degrees.
The quake caused alarm among the inhabitants of the cities affected by the earthquake of February 27, who feared a possible tsunami. At that, the President Sebastián Piñera arrived at the headquarters of the National Emergency Office (Onemi) near the 20.00 next to Deputy Interior Minister Rodrigo Ubilla to exclude the danger of tsunami and calling for calm.
Onemi director, Vicente Núñez, said there were no material damage to the buildings or were homeless. “We had saturation telephone lines, partial cuts power and self-evacuation in some villages in the Eighth and Ninth Region,” he said.
Stools
In the coastal area of La Araucanía, in the areas of Puerto Saavedra, Tortel and Carahue, residents decided to move voluntarily to the hills, as a preventive. The same thing happened on the shores of the Bío Bío Region, where the inhabitants of Talcahuano also left the beach.
In Tome and Dichato, people who enjoyed the beach decided to leave the place, a situation that was made without mishap. Meanwhile, waves of more than five meters square Duao flooded, located in the province of Curico, causing fear among locals and tourists. Although they were announced in advance, is not expected to be of such magnitude. The regional Onemi ruled that they were related to the strong earthquake.

Thanks for the pointer!
That Vukcevic graph is interesting, but it’s going to take me some time to fully grasp what it’s saying. Looks like the magnetic trigger for quakes on a first glance, though.
I am still centered on the inactivity in the CSZ and worrying about what that may portend. The only thing I see in that area are still some small EQ’s near the Mendocino Triple Junction. The CSZ is eerily quiet off WA andn OR and this doesn’t seem normal for a subduction zone to have nothing at all, especially as the Olympic Peninsula is winding like a slow spring! I am trying to remember if there were any foreshocks to the great Dec. 26th EQ of 2004 that may have presaged it – does anyone remember? I get the USGS alerts, but don’t remember seeing anything in that area until the big one. I heartily agree about the “foreshocks” – they do bear having an eye kept on them, but my greatest concern, having family and dear friends from the Bay area to Vancouver, B.C. is the CSZ.
“So we had a boat load of big ones in the area around Tonga, Indonesia, and even some up toward Japan. Now it’s rocked back over to South America. I feel like I’m sitting in a shooting gallery and folks are getting hit all around me”
I am noticing that this is all (or mostly) subduction thrust activity, not so much “strike slip” activity that we have in California. If I were in the Cascade Megathrust seismic zone, I would be getting a bit nervous.
http://en.wikipedia.org/wiki/Foreshock
It seems that the 2002 EQ is regarded by many as a foreshock to the great 2004 EQ. It was a 7.3! There has been nothing like that in Cascadia, and it looks like there were no small EQ’s in that zone prior to the big one. This only heightens my concern regarding the CSZ :(
As far as the EQ’s off Vancouver Island, I am not sure, but I think they are part of another zone, but one that may affect the CSZ, perhaps tightening the tension, but my guess is they would not have relieved any of the tension building in the CSZ. If I am incorrect, please feel free to enlighten me!
Hmphf… 4.6 in Utah, of all places.
I don’t like bigger ones showing up on the line headed toward Yellowstone… really really I don’t…
(Sidebar: FWIW, I’m making a CSZ monitor page you can bookmark that has those specific maps in it. Nothing there at the moment, but “For that day”… (Remember in “3 Days of the Condor? Albert talking… ) So don’t panic when you see “CSZ Quake” posting show up in a couple of hours, OK?)

@E.M.Smith:
About that graph from Vukcevic: It says that there was a big change in magnetic field, but we must remember that at 90 degrees from magnetism it is electricity and also the fact that these earthquakes, differently from years ago, are happening at low depth.
In the case of the last year big one at Concepcion, current plate tectonics dogma expected the contrary to what really happened: Chile grew three meters westwards then. Though some forecasted even its approximated magnitude:

Covers a lot of earthquake, volcano, climate… you may like to give it a look.
Kev
That area of Utah, from about Veyo in the South, along a line to the East of Interstate 15 is very volcanic. There was an eruption recently (in geological terms) at Panguitch which is still not covered with vegetation. It is just barren lava flow.
There are plenty of cinder cones in that area as well.

As the late George Carlin said:
“Get your sh**s folks, WE are leaving…”
Still got 5.x size going off all around. Then there is this one… yeah, not quite another 7.x in Vaunatu, but still:
