Earthquake Report

I thought it might be a good idea to start a thread where we can  keep an eye on and discuss earthquakes for those of us who are "quake watchers."

The 6.8 just happened about 40 minutes ago and was followed by a 5.3 about 10 minutes later.

Earthquake Swarm Continues in Fillmore Area; Includes More Than 50 Temblors

Dozens of small earthquakes struck the Fillmore area this week, but the swarm was dying down, a Caltech spokeswoman said midday Thursday.

The temblors began Wednesday, with the first quake at or over the 2.0-magnitude level striking at 4 p.m. about 4 miles west-northwest of the town of Fillmore, in rural Ventura County.

More than 50 quakes struck the area, U.S. Geological Survey seismologist Lucy Jones said on Twitter Thursday morning.

All earthquakes make another quake more likely, so more temblors would “probably” occur, Jones said. There was no way to know if a bigger quake would strike, Jones said.

Only two of the quakes rose above the 2.5-magnitude level, both of them on Thursday: a 2.8-magnitude quake that struck at 6:33 a.m.; and a 2.6-magnitude temblor that occurred at 11:04 a.m.

But around noon, a spokeswoman for Caltech, where Jones is a researcher, said the Fillmore swarm was dying down. Earthquake experts from the university did not plan to address the swarm unless that it started up again, Caltech spokeswoman Deborah Hedges said.

Thursday evening, several more small quakes were reported in the area.

The Fillmore area was struck hard by the 6.7-magnitude Northridge Earthquake in 1994, with many brick buildings collapsing in the historic downtown.

Known for its citrus groves and agriculture, the town is about 45 miles northwest of downtown Los Angeles. It has a population of about 15,000.

.@michelineLynch Over 50 small EQs near Fillmore. All EQs make another more likely, so probably have more. No way to know if one'll bigger.

good to keep informed. but glad where i live, there are no major jolts.

 
 
 

I agree Storm its good to stay informed. I've had my eye on that Fillmore California swarm for a couple of days now.

Thanks for the watch thread. 

You are welcome Pooky!

California has been very quite for a while, but over the past week or so there has been an uptick in activity state wide. Here is a link to UC Berkeley's Seismo Lab. You can zoom in and out on the map to get a better idea of what's going on

I have a sister and her family who live in San Luis Abispo California.
Quakes and drought... hmmmm.

Cool! Thanks. My brother's in Puerto Rico and I always keep an ear out for that area for sure. 

I sure wouldn't want to be a Californian...too much to worry about there.

Yes CM there is a connection. For example, the quakes near Geysers California are a direct result  of the operations at The Geysers Geothermal Field. http://www.geysers.com/geothermal.aspx

 

The Geysers Geothermal Field in Northern California is the largest single geothermal field in the world (over 800 MW in 2009 and increasing as EGS activities carry forward). Seismicity related to production and injection has been observed since the 1970s and has been used as a general indicator of fluid paths and reservoir response. An increase in injection rates using wastewater from the areas of Santa Rosa and Lake County, CA, has recently raised concerns regarding the impact of injection-related seismicity on nearby communities.

Have a look at the map "EGS: Interactive, Real-Time Map of Earthquakes at The Geysers" 

http://esd.lbl.gov/research/projects/induced_seismicity/egs/geysers.html

 

California is out of water. The aquifer is in trouble. They are pulling water to run geothermal power and causing quakes. It's a no win situation.
