  • IRIS - Overview
    for fieldwork was sent out on March 3 2010 and resulted in more than 50 responses Based on this enthusiastic response the endorsement by the IRIS Board of Directors and an invitation from the University of Chile a proposal was developed and submitted to NSF that requested funding to cover the transportation and field expenses to deploy 60 broadband PASSCAL and USArray instruments in the epicentral area for approximately six months and produce an open community dataset Susan Beck and Sergio Barrientos of the University of Chile were identified as the primary scientific leaders and Ray Russo University of Florida and Steve Roecker Rensselaer Polytechnic Institute were chosen to lead the initial field deployment Other teams from the international community including Germany and France have also responded to this unprecedented opportunity The deployments and subsequent data collection and research will be carried out in close collaboration with the University of Chile in Santiago The University of Chile team is led by Sergio Barrientos along with faculty members Diana Comte Mario Pardo and Jaime Campos Susan Beck and Steve Roecker arrived in Santiago on March 14 and met with the groups from the University of Chile France and Germany to discuss coordination of station siting and to make arrangements for arrival of the IRIS equipment The initial IRIS deployment consists of 60 PASSCAL stations of which 50 are equipped with USArray Flexible Array broadband seismometers and 10 stations that have strong motion accelerometers Transportation of the equipment to Chile on March 21 was kindly arranged by the US military s Southern Command SouthCom and coordinated by USAID s Office of Foreign Disaster Assistance Three teams each consisting of one engineer from the PASSCAL Instrument Center one member of the US academic community and one or more representatives from the University of Chile are carrying out the initial deployment In addition to Steve Roecker and Ray Russo the initial US team consists of Anne Meltzer Lehigh University and Angela Reusch North Carolina A T State University along with Bob Greschke Brian Bonnett and George Slad from the PASSCAL Instrument Center Additional volunteers will be selected for later stages of the deployment and for servicing and removal of instruments A set of eight PASSCAL instruments had arrived in Chile just before the February 27 earthquake to be used in a study at Villarrica Volcano by Greg Waite of Michigan Tech and the group led by Kalus Bataille at the University of Concepcion Although these instruments went missing for a few days following the earthquake they were eventually recovered and it was agreed that these instruments could be installed pending the arrival of the main shipment of IRIS instruments on March 22 These instruments were installed March 17 19 in the southern part of the rupture zone near Concepcion The array of broadband instruments will be installed using well proven field procedures developed as part of the PASSCAL and USArray programs The instruments will be deployed for up to six months with on site

  • IRIS - News From the Field
    Installations Completed By Anne Meltzer on April 2nd 2010 George Mouse Brian and I are in Santiago We re expecting Ray Mario and Bob any time now If they were successful today all the stations will be installed George and I installed T6 PTN2 and T8 yesterday Our luck with wonderful hospitality and good food continued At our last station which we installed as the sun was setting the folks at the house invited us to sit on the porch with them when we were done They served us sprite tea bread with avocados and warm fresh homemade doughnuts I am not making this up A very nice way to finish up our installations I fly back to the US tomorrow I ll work on my accounting now and make sure the directions for all the stations are clear on the installation sheets at least as clear as turn left at the gravel road can be Ciao Wrapping Up Soon By Anne Meltzer on March 31st 2010 On Tuesday we installed the stations in Hualane and Duao The stations in Peralillo and Pichilemu were installed today We didn t get to T6 today We ll do that tomorrow along with T8 and PNT2 It took us a bit of time to find a site at Pichilemu but we did find a nice site at a small school Six kids ranging in age from 6 to 10 or 11 got a lesson in broadband seismology We ll forward a photo Also the empanadas in Pichilemu are very good You ll recall that at Hualane we received coca cola and a homemade Easter cake to take with us when our installation was completed Today at Peralillo George and I each received two bottles of wine compliments of the general manager of Los Vascos Winery where U67B is installed We plan to install T6 T8 and PTN2 tomorrow Thursday If they re up for it we ll send Ray Mario and Bob on a coastal run to install Navida T5 PTN1 and T7 That should take two days By Friday all the stations should be in Another Team Member Arrives in Chile By Susan Beck on March 31st 2010 Ray Russo arrived in Santiago on Monday Steve Roecker brought Ray up to speed on the current field activities before he returned to the US We now have an updated deployment map showing the locations of all the installed instruments Thank you Ray 32 Stations Now Operating By Steven Roecker on March 28th 2010 As of this morning we have 32 stations operating The loaner sensors in all but three of the original 8 sites have been replaced with sensors that arrived from the U S last week Also note that we are installing Episensors at some sites with 6 channel data acquisition systems I don t know how we want to do the nomenclature for multi sensor sites maybe count them as two stations Finally we will be doing a short term overnight deployment of 6 Episensors in the Concepcion area tonight Sunday We should finish the southern part of the deployment by Tuesday The remainder of our work will be between Curico and Santiago Cheers Steve PS Just felt a pretty good sized event here in Chillan as I typed that signoff I m going to guess magnitude 5 3 Equipment Has Arrived By Steven Roecker on March 22nd 2010 Shipment with equipment arrived last night about 8 30PM too late for the Chileans to unload it We got to the airport this morning about 10 AM too early for the Americans to show up to open up the plane Finally got eveyone in the same place about 1PM Unloaded trucked to the university and offloaded We are ready to go With any luck the equipment heads south tomorrow with our first deployment team So far so good Pallets of equipment are inspected after arriving in Chile Photo by Steve Roecker Eight Stations Deployed By Susan Beck on March 21st 2010 Steve Bob and Mario arrived back in Santiago last night and have 8 stations deployed in the southern part of the rupture area Anne Meltzer arrived this morning Based on Steve and Bob s experience we are meeting this afternoon to update our plans for station locations logistics materials needed etc It was good to have this experience installing the initial eight stations as it will make the main deployment go better One small issue is where to get sand It is a large volume to take in the trucks but the ground is pretty much clay so there is no local source of course we can buy the sand and transport it or buy it in Concepcion and transport it The equipment should arrive today and clear customs tomorrow Steve and Diana will go to the airport in the morning Steve and Bob tried google earth maps but it does not work that well in the field lots of vegetation and gaps in the coverage so we have some road maps electronically that Sergio got for us that we may try to print out We are still not sure how well they will work Sergio and I filmed with the Discovery Channel for several hours yesterday at the University I have no idea how much if any they will use The program is about how lessons learned about the Chile earthquake can be used for understanding the Pacific Northwest earthquake that is expected That is it for today I leave tonight Updates will continue but not as often as the teams will be in the field Making Progress By Susan Beck on March 19th 2010 Mouse Reusch arrived this morning Steve Bob and Mario have 5 stations installed and hope to have 3 more installed today and then return to Santiago on Saturday Steve will probably send an update tonight They have been putting in very long days They met with the Discovery Channel people for one of the station
