    The new SCEC stations and PASSCAL IRIS stations that provide data in real-time to the network will provide data right away to all researchers. No longer waiting for funds and personnel to post-process the data! The data from the older SCEC instruments that get deployed will be provided in raw format to anyone who requests them, however, a processed data set will depend on funding and personnel commitments.

    I was able to "fly" the length of the fault rupture* on the afternoon of the 13th to confirm the extent of surface faulting. Attached are waypoints and observations as we flew along the rupture. *courtesy of Google Earth in lieu of Civil Air Patrol

    I wasn't sure, but it appears registration is required. I will confirm after hearing from the EERI IT guy when he arrives at their office....rcl

    I assume the Pasadena operations are history..... Will (can) SCEC continue to communicate? The Clearinghouse is in operation. Email can be sent to cgs_golden_guardian@conservation.ca.gov. My cell number is 916-813-2274.

    Just to clarify - do we need to have a login to even view the information or just to post? I may have missed a link to an area where we could view postings without logging in.

    That hadn't occurred to me - interesting idea. Are the permitting issues to consider with their deployment?

    The 5 short-period ocean bottom seismometers from the WHOI/USGS rapid response pool will be on a plane for the southwest today and likely be read yfor deployment tommorow. Any suggested locations within the Salton Sea for capturing aftershocks would be helpfull.

    So that critical, hypothetical 3 am phone call would be directed to Golden.

    UNAVCO will commit to deliver 25 campaign GPS systems to Indio in response to a coordinated multi-group request forthcoming from Jess and Rowena (details to follow) as well as 20 systems for Rick Bennett to occupy points in the ECSZ in Joshua Tree N.P. We expect that 5 UNAVCO trucks with two field engineers each would arrive in Indio late Saturday morning.

    The USGS Pasadena exercise is winding down -- Erik, Morgan, and I are here for just a few more minutes. An advance heads up: if an especially large aftershock were to strike within the LA metropolitan region in the wee hours of the morning, the Pasadena office and Seismo Lab would be knocked off line, and Golden would be stepping in with primary reporting authority and response responsibilities.

    Standard rate daily GPS files from PBO and other permanent stations from 11/13 (jday 218) are available in ftp://data-out.unavco.org/pub/rinex/obs/2008/318 as they come in. Stations close to the rupture were prioritized by request and are there as of 5PM PST.

    Here are updated aftershock probabilities based on the first 7 hours of aftershock data for the scenario event: So far activity is approximately the average expected for California. We are using generic aftershock parameters since we have less than a day of aftershock data; therefore these are aftershock estimates that may change. Furthermore, if there are more large secondary aftershocks, the sequence may become more active. So far there have been 23 M≥5 aftershocks. The largest aftershock occurred at 12:00 pm PST, and had a magnitude of 7.0. Secondary triggering from this aftershock has been included in the current forecast. Within the next hour (5:00 pm – 6:00 pm PST) we can expect approximately 7 M ≥ 4 aftershocks, and 1 M ≥5 aftershock. Within the next 12 hours, we can expect approximately 52 M ≥ 4 aftershocks and 5 M ≥ 5 aftershocks. The probability, from this time forward, that at least one earthquake larger than M 6 will be triggered is 80%. The probability that an earthquake larger than M 7 will be triggered is 12%. The probability, from this time forward, that an earthquake larger than the M 7.8 mainshock will be triggered is 2.6%. This probability will fall with time if no exceptionally large aftershock occurs.

    Thanks for sending those in. A number of people have reported degraded sat phone performance today. That couldn't be because of the ShakeOut exercise, could it? If so, they would likely not be very useful in a real event.

    Just gave 12 virtual slip measurements to Erik ounders over the telephone. Dispalcement averaging ~5-6 m, poure right-lateral, very little vertical. Offset efatures include paved and dirt roads, fence lines, a motorcycle track, and an offset... baseball field and golf fairway. Having trouble with two of the three USC sat phoens, unfortunately. They all worked fine two weeks ago, si this is opuzzling and a bit worrisome...

    Sinan and I are safe in Irvine with no satellite phone, but plenty of water. We will not make it to the Indio field site.

    From PBO Permitting Coordinator Kyle Bohnenstiehl: Plan on having $1500 per site available for permitting with private land (both individuals and corporations). We will not be able to get on federal, state or county/city land on short notice. This is due to the fact that regulations would get in the way. Private landowner cooperation in this case is almost 100% assured, possibly for no cost in most cases. However, having $1500 available per site would ensure success. Hearst and some large ranching enterprises (Varian, Vogel, etc) might want more $$. It is just hard to say without asking. I called Angeles National Forest and spoke to my contact there about a situation just like this. She said it is possible that under an emergency situation we could get out on their lands (non-wilderness) in a week or so but she was unwilling to commit or ask her management unless it was a real situation. This is something USGS and UNAVCO should look into in the future. UNAVCO would want to be the permit holder on these sites. We would use our standard form. I estimate it would take me 4 hours of labor to permit a site however in reality the on site people would probably be taking care of most of the paperwork and just getting a copy back to me. Figure around $300/site for permitting overhead in addition to land rental fees. Our contract recon costs averaged around $3500 per site during PBO. All of this expertise resides in the So Cal area and I would assume these same contractors would be available for this type of work in case of emergency. Contractors could probably identify a suitable site at the rate of 1 a day depending on how impaired their mobility is.

    Scott - I'm plotting flt rupture observations in GIS. Your coordinates plot near the Ludlow flt in Mojave Desert. I'm assuming coordinates actually are: -116.1861, 33.7404 These coordinates plot on SAF where it crosses Landmark Parkway in Terra Golf Course, Indio. Bill Bryant

    I just made it out of the building (well, actually just got back from our earthquake fair) and contacted IRIS about instruments - thank you for giving them the heads-up. We have 10 RAMP stations, five with telemetry, from IRIS that will be shipped out today and received in a couple of days. In the coming days we will be preparing the field equipment to go out - and trying to get the batteries and other equipment out of labs that are in badly damaged buildings. Anyone wishing to help can call me on my satellite phone. We will decide on a meeting place shortly.

    Here are updated aftershock probabilities based on the first 4.5 hours of aftershock data for the scenario event: So far activity is approximately the average expected for California. We are using generic aftershock parameters since we only have 4.5 hours of aftershock data; therefore these are aftershock estimates that may change. Furthermore, if there are more large secondary aftershocks, the sequence may become more active. So far there have been 19 M≥5 aftershocks. The largest aftershock occurred at 12:30 pm PST, and had a magnitude of 7.0. Secondary triggering from this aftershock has been included in the current forecast. Within the next hour (2:30 pm - 3:30 pm PST) we can expect approximately 11 M ≥ 4 aftershocks, and 1 M ≥5 aftershock. Within the next 12 hours, we can expect approximately 70 M ≥ 4 aftershocks and 7 M ≥ 5 aftershocks. The probability, from this time forward, that at least one earthquake larger than M 6 will be triggered is 83%. The probability that an earthquake larger than M 7 will be triggered is 14%. The probability, from this time forward, that an earthquake larger than the M 7.8 mainshock will be triggered is 2.9%.

    In real life I've got a few minutes between classes to post something here. In the scenario, I probably wouldn't be posting anything right now, because the power would be out. Athough I might be able to run my computer for little while off of my GPS batteries (assuming they are charged up) using a power inverter. On the other hand I might be helping to rescue people trapped in damaged buildings on our campus, less than 1 km from the fault. If I'm not injured, I'll probably be running out to the fault to see how big the surface offsets are. I suspect that at this time my students who have GPS experience are trying to contact family members and check on their homes, but I'll try to get as many as I can to help with GPS data collection. Tomorrow might be the soonest that I could send anyone out into the field to collect GPS data. Until the power comes back on (in a day or two?) I won't be able to recharge any of my GPS batteries after use. If any other group is able to begin observing some of the sites assigned to CSUSB that might be a good idea, just let keep us posted, so I know which ones are still on my list. I'll probably sleep in my car on campus tonight. I doubt if I will be able to get home to Crestline. Gotta run to class. More later. Sally McGill
