Professional Network Operation
The IRIS Model of Cooperation
As CNSS Chairman I have made the point several times that I feel that the permanent seismic networks must not continue to be run only as science experiments. While many
IRIS has shown that seismologists can get together, organize, and work on common goals which result in more and better resources for seismic research. IRIS has been a great success.

H O W E V E R , there are aspects of this model which do N O T directly transfer to the permanent seismic network operations. NSF and IRIS are pure science organizations, USGS permanent networks are not (as mentioned already). Primarily one institution, NSF, funds IRIS and the research using IRIS facilities. NSF'S job is comparatively simple: fund highquality science through a peer-review system and support that science using the IRIS facilities. NSF does not engage in doing science itself nor run the facilities. The permanent networks, on the other hand, operate in a very different environment. The USGS (which supports only about two thirds of the permanent network stations) both funds and operates networks itself. It also funds and does research itself on the data from the networks. The situation is further complicated by the position USGS occupies within the Department of the Interior, where there are a plethora of missions unrelated to seismology, research, or even geology. So, the situation is not simple. There are all sorts of possibilities for conflicts of interest, working at cross-purposes, duplications, and inefficiencies which NSF and IRIS just do not face. We can learn by the cooperative process among the seismologists who got and keep IRIS going, but I feel it is naive in the extreme to think we can just copy that model.
Turf Battles We mostly understand and appreciate the competition inherent in an active and vigorous research community. We compete for research funds, research credit, promotions, and data access. The attitude still remains that if I bust my butt collecting data, I get first crack at it. IfI locate an earthquake first or best or it's in my backyard, it's my earthquake. This is our history; it goes back to the Byerly/Gutenberg line of the 1950'S or before and still may be appropriate for individual research projects. For permanent networks providing data for many purposes, though, I don't think this is appropriate. While things are getting better, we still have cases of mistrust and noncooperation between different networks, particularly between a regional network and the National Seismic Network because of their overlapping jurisdictions. This is often only a case of miscommunication, resulting in rumor or innuendo rather than a true conflict. Things are moving in the right direction. We can accelerate that motion if we all value and recognize the need for cooperation among networks rather than competition.
Strong-motionJWeak-motion Integration This topic is an extension of the above topic of turf battles but is accentuated by our widely different histories and clients. Strong-motion data are the future for earthquake hazard mitigation efforts, be it for engineering purposes long after an earthquake has happened or within seconds of an event for real-time warning systems. The separation of the strong-motion verses weak-motion communities must break down. tt is happening in Southern California, with some effort and bumps in the road from what I hear, but it is happening and the results are promising. The model of a
national strong-motion program (NSMP) being run totally by one group from one place for the whole country makes no more sense than all conventional seismographs being run only by the USNSN group in Colorado. The NSMP must involve, coordinate, and cooperate with regional network groups for all of our sakes.
Cooperative Technological Developments I have been in the middle of what I am calling the Earthworm~Antelope fiasco. I call it a fiasco not because of the technological products which now exist (which are quite impressive), but rather because of the process by which we have arrived where we now are. The process has stunk. A little history for illustration is needed. The Earthworm effort was originally talked up as a modular, scalable networking, recording, and processing system born in the early 1990's from a meeting of network operators called Alta-II. The developers proposed, and some of us strongly supported, the idea that with a base system going others could join the group and contribute improvements, separate modules, and ideas to the system. A talented group from the University of Alaska was the first to make such contributions. However, their contributions were slow to be adopted by the original Earthworm team (though many eventually were). Alaska grew impatient, and there was a falling apart of this cooperative effort. A little over two years ago, several of us on the sidelines saw this happening and hoped to "fix" the process, i.e., get the original model of participation by many back on track. The creation of an advisory group of people interested in the cooperative development of Earthworm was formed at a CNSS meeting. Unfortunately, this group's efforts have been almost a total failure. Other than one request for the production of Earthworm documentation (which the original development team then did produce), nothing has resulted. Few of its members have taken any responsibility for directing or suggesting developments of Earthworm. However, independent of the advisory group, there has been ad hoc participation by several different regional networks which have contributed software, bug fixes, and suggestions which have slowly been making Earthworm a viable system. Unfortunately, not all networks using Earthworm code have so reciprocated. Some of the larger networks, some with lots of resources and talent, have taken, used, or adapted Earthworm code and not provided anything in return, not even bug fixes. Also, some networks seem to think that Earthworm should be provided to them and run for them, and they need not take the responsibility of learning its subtleties. O f course, the whole network data processing system "fiasco" has gotten more complex with the arrival on the scene of Antelope, which in some ways is a direct competitor to Earthworm and in others a nice complement to it. While I don't want to get into any of the technical issues of Antelope, as an aside, it's my opinion that Antelope is nowhere near the Messiah its fervent supporters claim nor the devil its

detractors might suggest. Like many things, the truth lies somewhere between the extreme positions. It seems a good system with some very strong points, but with some difficulties which may be largely related to its proprietary nature. There has now developed what would seem to be two "camps", the Earthworm camp and the Antelope camp. Both systems seem to be quite viable and potentially very complementary. Unfortunately the "process" for taking advantage of this potential complementarity has broken down. Whatever happens in the future regarding such technical issues, I would hope that the process can be open, with participation, in good faith, by all.
