2013 Oklahoma Earthquake Discussion

[venture]

Welcome to the 2013 version of the earthquake tracking thread.

Update 12/23 - We've moved this page over to the Wiki format. Since 2013 is almost done, there won't be a lot of updating to the page except to get some needed resources added in.

----

Oklahoma is home to many fault lines. The two most active areas for the 2012 period was the earthquake swarm zone just to the Northeast of Oklahoma City. The most noticed area was along the previously thought dormant Wilzetta Fault line to the east of the Oklahoma City area. This is also know as the Seminole Uplift.

This map is updated with all earthquakes recording by the monitoring sites in Oklahoma, and most of these quakes do not register on the USGS site.

Also added is the catalogs page that has documented all (recorded) earthquakes in Oklahoma since 1897, even though most monitoring didn't start until about 50 years ago. Leonard Geophysical Observatory - Catalogs

I don't know how to embed real time maps, but here is this link. Is interactive.

Also here is the story on Fox News. http://www.foxnews.com/us/2013/01/05...unami-warning/

Looks to be somewhat significant, but you never know with these things.

Strong earthquake jolts Alaska, sparks tsunami warning | Fox News

The magnitude 7.5 quake did generate a tsunami, but the Alaska Tsunami Warning Center said the waves didn't pose a threat.

Eh, it turned out to be nothing.

Wow 8.0 in the Santa Cruz Islands, NE of Australia at about 6:23. Can't believe my dog could sense that one too.

Thanks

[LocoAko]

Didn't feel a thing in south Norman. Blah.

[Roger S]

I don't have a clue if it was felt in Moore. I'm having foundation work done today. My whole house has been shaking since about 8:30 this morning

Hmmm...might have heard the rumble with that one, but have people working on the neighbor's roof a couple doors down - so not sure.

Apparently it shook Mark Rogers on the Sports Animal. BBJ did some digging and said they rated it at 3.4.

[Lauri101]

We've felt two today - one at 10:56 and another about 11:35. They rattled the house and sent the cats running in crazed circles.
