Nevada Earthquake Swarm

There has been increased earthquake activity in Nevada over the past week or two. Nothing big, but a lot more of them than usual. There has also been a slight increase in Oregon, Utah and Washington.

There gas been increased earthquake activity in Nevada over the past week or two.

Gas can do that I guess. I hope its just normal gas and no big quake !!

wow, i opened this thinking it would be
something small, but man, that is a LOT
of shaking going on in a day.

good find op, hopefully our resident quake
minds will come in shortly and give us a
opinion of what they see.

Wow thats intense. Keeping my eyes on this one for sure!

The list of the new Nevada quakes can be found here:
earthquake.usgs.gov...

What I see is evil, evil magma sliming and slithering its way east underground from the Long Valley supervolcano to come and get you. When it rises forth, the face of Satan shall be seen in its midst, and will cart you off to hell. I mean after all, it is only two days till we all die.



It's a tiny quake swarm, shallow, and that's about it.

Something I find weird and maybe someone can clarify for me. But when I go to USGS and change the slider to all last 7 days I find it odd that yes your swarm can be confirmed. But it shows no small EQ's for any areas besides North America, now is that just because its the United States Geological Survey and only tracks small quakes for the US. Cause looking at the map you would get the impression that the rest of the world has no small shakers just 2.5+ if ya get what im saying

They only track 4.5 or higher. A decade ago they tracked them all, then raised it to 2.5, then again a couple of years later to 4.5, and through all this, their statistical number of quakes stays the same, so that in all actuality, quakes have risen over the past decade, but their stats will tell you they haven't. I'm no expert on this, wondering if Puterman can show me that this idea is wrong, or flawed thinking.

Ya eh, I only ask cause I would figure that changing the slider would and should show many small ones in say Japan but when I did nothing just the ones that make a splash so to speak. Thanks for the explaination. Do you happen to know the site that would track world wide swarms besides the USGS website??

Here is USGS disclaimer - below that I put a link to a page that has some downloads for smaller quakes.

The maps and lists show events which have been located by the USGS and contributing agencies within the last 7 days. They should not be considered to be complete lists of all events M2.5+ in the US and adjacent areas and especially should not be considered to be complete lists of all events M4.5+ in the world. Beginning January 1, 2009, earthquakes outside the US below M4.5 are not reported unless NEIC obtains felt reports. The World Data Center for Seismology, Denver (a part of the USGS National Earthquake Information Center) continues to receive data from observatories throughout the world for several months after the events occurred, and using those data, adds new events and revises existing events in later publications.

Here is the LINK to the page that shows all 4.5 and higher worldwide and 2,5 and higher for the U S.

LMFAO , omg thats hilerous .. i wonder if i could write a scarastic reply better then you did ..

thanks for making me laugh..

on a serious note i agree with true american here ..

At work I leave that interactive map running in the background while I do my drafting, I was looking for something that covered small quakes in places besides North America like say Japan or Fiji. And on the map you provide a link to only outlines small north american quakes when the drop down menu at the top is at last 7 days all nothing for the rest of the locations on earth.

Try this LINK. Look in the upper left corner of the page for the "choose data feed" pull down menu. You can get everything for 7 or 30 days. Then under the map you can scroll down the listings.

Treading water here. OK I use the same USGS map you have posted the USGS.GOV site now if you follow your own direction then say go click over Japan and zoom in all you have is 4+ pointers I am looking for a map that will show below 4 pointers this map does not do that it only shows small quakes for North America. I would like to find a similar site that is more thourough for places not in North America so as to see what sort of swarms other hot spots such as Samoa, Fiji, Japan, ring of fire locations not in north america. Hope that helps clear up what i'm looking for off to google I go, best way to find something is do it yourself like I should have done in the first place.

Sorry, that's all I have. When I get some time I will look for something more all inclusive.

Check this out and see what you can open in here

worldwide quakes

I understand what you are asking. Different countries and areas are covered by different organizations. The areas can be wide or very specific.

If you ever have questions about earthquakes and where to find information, you can always go over to Quake Watch 2012. The quake watchers in that thread know where to find everything, or almost everything related to earthquakes.

Quake Watch 2012

Read the first post as it lists many resources. Also, Puterman, who hosts that thread, has a link to quake and volcano links in his signature, that will give you the information you are looking for.

Link to earthquake monitoring websites

I hope that helps, as there is information on earthquakes for every area in the world. The page also covers many other things related to earthquakes and volcanoes, and I would recommend it to anyone who wants to learn more.

On topic, while that does look like a swarm in Nevada, it does not seem like anything to be concerned about or TrueAmerican would have let us know that the world was going to end soon.

After seemingly calming down for a while with only a couple of minor burps, it now looks like it is picking up steam again. Look at the short intervals in this last group of quakes. Also, this group is all in the same small area.

Interesting. Where are these times that are listed based on? It's not Nevada time, just wondering. Also, I saw a mention on LA sink hole thread that there is some activity today along New Madrid fault line, do you know if there is any truth to that?

The times listed are UTC time. You have to subtract 8 hours for east coast time and more for time zones further west.

No, I haven't heard anything about activity on the New Madrid. I will look into it though.
ETA - I just looked at my quake sites and there is nothing showing. If there is any activity it would have to be very minor.

We can also add these to the list above. And they are still way too close together.
