Thanks Joanne,  It would be the Ormat Brawley North plant that

is relevant.   I don't know anything about that plant, but most in

the salton trough have to report the seismicity in their region to DOGGR.

Hence they run local networks, such as the Cal Energy data from further north

that is now archived at CalTech.

The attached google earth capture shows where the plant is as "A". It's

about 1km from the epicenter of the M5.5.   I don't know anything about

their well locations, but presumably they are within a few hundred meters

of the plant.  I think it would be great if SCEC as an organization was pro-active about

making sure the local data gets archived somewhere if it exists.  This did not happen for

the 2005 swarm under the Cal Energy plants and that was a major missed opportunity.

Screenshot with TerraSARX coverage and dates

TerraSAR-X (TSX) has an 11-day repeat cycle, which helps enable acquisitions sooner, but unfortunately the German data security laws mandate 5-day delay after acquisition for full-resolution data. 

We will see if the TSX data acquired over this area previously can be included in the Los Angeles Supersite to make data access easier.

 Attached are Google Earth files with seismicity (ANSS catalog is updated daily and real-time is every 5min I think, Hauksson-Shearer) and USGS fault surface traces.

   Well that's interesting.  Can you post a map?

We've computed GPS displacement waveforms for the two largest events: at 19:31 and 20:57. There is about 1.5 cm of East motion at a few stations nearest the epicenters.

Actually, Carl Johnson's thesis is a good reference for the 1970s  Bernard

It looks like this one is just south on the big 1981 West Moreland swarm (largest M5.7)

which lasted about 200 hours

Is anyone in the area able to document/rule out a surface trace/scarp

from this swarm?  That info came in very handy in figuring out what went on in the 2005

swarm.

On the older Iridium sat phones, hold down the zero key until a + pops up on the display, then type in the rest of the number.

Dear colleagues,

I would like to draw your attention to the following Special Session - convened by Gareth Funning of UC Riverside, Semih Ergintav of TUBITAK MRC in Turkey and me - on the recent Van earthquake for the upcoming SSA Annual Meeting (see http://www.seismosoc.org/meetings/2012/). The meeting will be April 17-19, 2012 in San Diego, California. I hope you have a continued interest in this earthquake, having previously contributed to the Van Supersite, SCEC Response site or been in communication with me directly about the event.

Please consider submitting an abstract to this session on an important recent earthquake, and please forward this call to your colleagues and collaborators as appropriate. Abstracts are due by January 11, 2012.

We hope to see you in San Diego in April!

Regards,
Mike Floyd

The October 23, 2011 Van, Turkey Earthquake:  Observations and Implications

The October 23, 2011, Mw7.2 Van earthquake in eastern Turkey is the latest of a number of recent large (M~7) earthquakes to cause many deaths and significant damage in a continental setting. This earthquake occurred in a tectonically complex area of convergence and right-lateral shear between Arabia and Eurasia, far from the recognized major plate boundaries, and with the relatively simple strike-slip systems of the North and East Anatolian Faults located well to the west. This session will focus on scientific, technical and social studies of the earthquake's immediate and long-term effects. We welcome contributions from the fields of seismology, geodesy, geology, engineering, and governmental and non-governmental response that provide insights into all aspects of the earthquake cycle in the area, the regional tectonics and structure, and the local impacts of the earthquake and its aftershocks. Studies that highlight comparisons to, or lessons learned from, other similar major earthquakes in the last few years, for example the Haiti and Christchurch earthquakes, and that discuss implications for analogous areas of oblique convergence in California and elsewhere are also encouraged.
