No Earthquakes in Yellowstone region for the last seven days

and hopefully never in our lifetime. Just never seen the Yellowstone region on the USGS site show no activity for 7 days before.

Epic Fail, there were five recorded activities in the 6 days before you posted:

Sorry, double post. Stupid net nanny thing at work.

So it appears there's nothing to fear

Good for you for taking that simple step of writing the USGS. I have written before to the people at the YVO, and they are quite responsive and polite. They are also the foremost experts on the park itself. For any future questions, consider writing them for straight answers. If that park even peeps the wrong way, I have every confidence in the fine people there to take the appropriate action. Of course, their words on the matter will never be enough for some...

Trying to equate Yellowstone to other volcanoes and the silences those volcanoes show as "calm before the storm" just really shows a lack of understanding of the differences between the vast complexities of Yellowstone and other average volcanoes: They are different animals.

Yellowstone is currently experiencing a period of relative calm and subsidence- but as recently as June:

During the month of June 2010, 131 earthquakes were located in the Yellowstone region. The largest event was a magnitude 2.9 on June 25th at 6:07 PM MDT, located about 15 miles south southeast of Old Faithful, YNP. One small earthquake swarm was recorded from June 6th through 12. The swarm included 47 earthquakes with magnitudes ranging from 2.2 to -0.5 and was located 6 miles east of West Thumb, YNP. Seismicity continues at background levels.

Ground Deformation Summary: Continuous GPS data show that uplift of the Yellowstone Caldera has ceased for now. The WLWY station, located in the northeastern part of the caldera, underwent a total of ~23 cm of uplift between mid-2004 and mid-2009.

With uplift ceasing, anyone is going to have a tough time convincing me she's about to blow anytime soon. I have seen one article that even explores the possibility that YS is dying, and may never be a threat again due to long term magma movement out of the park in a northwestern direction, giving it essentially an effective pressure release path for the foreseeable future.

The Pacific NW just had a 5.3 about 80 miles off shore of Oregon this afternoon acording to the USGS. Cliff was pretty specific on this one.

excerpt from post:
Heads up please. In working through the longer term data, i had to go through some of the last of the immediacy stuff due to cross links. Within the immediacy data sets there are clear indications of a major [damaging] earthquake on west coast of america (MOST likely north america due to angular momentum issues of planetary alignment) and more probably than not, in the PNW perhaps down to mid CA. This quake shows as being completed with problems, *such as yet more [wedding interruptions] by August 3, however the data accretion patterns point to the last two days of July as the point of impact and largest number of after shocks.

IMO this sort of post would be more suitable in the Quake Watch 2010 Thread.

so what that you wrote them? if they knew the big one was getting ready to blow, the government would tell em to keep quiet and you'd be told everything is alright. not saying that recent inactivity is significant, but you really shouldn't put all your faith into one outlet of information

Sorry, got way off course with the 5.3 statement. Just responding to a comment on page 2 about half way down by MMPI2 mentioning this very event. Glad to hear the respoinses on the quet being normal in Yellowstone. The goverrment telling us this information does not hold a lot of confidence at this time, but the members who follow it closely telling the information does. Thanks

Then we can expect some conflagration, and I mean it quite literally.

There have been NO "greater than 1 on the Richter Scale(edited)" earthquakes in the Yellowstone region for the past 7 days. For such an active seismic region, this seems unusual. Edited " This is my observation from the USGS site soley"

The USGS site filters out seimic activity below 1.0 and I was not interested in the micro quakes provided by the Utah site. The 1.3 quake on your list came after my original post by 2 hours, and the other quakes on your list were either under 1 on the Richter scale, or fell outside of the 7 day filter for the USGS map. If you look at the Yellowstone area right now in the USGS site, you will see that the 1.3 quake is the only one above 1.0, and it did not even occur in the park for the last seven days. So there is still calm, except for micro quaakes, in Yellowstone. From what I have read in the comments so far, the calm is normal.
