The following are rapid, low-res scans of photos I took during the Tien Shan Seimic Station installation trip in September and October of 1997. This page is a preliminary summary of the trip - the emphasis here is on speed rather than asthetics or careful documentation. Better quality scans and a more detailed set of notes will follow.


Photos From the Kadji Sai Installation

Figure A1. Kadji Sai. Ruslan Dudinskih installing the GPS antenna to the top of a pole fixed to the vertical face just outside the vault.

Figure A2. Kadji Sai. View to the North from the entrance to the vault. Issyk Kul can just barely be seen as a horizontal line in the distance.

Figure A3. Kadji Sai. View of the interior of the vault. The CMG-40T sensor is located in the dark spot at then furthest end of the pier, behind the SKD sensors.

Figure A4. Kadji Sai. Mounting of the DAS and Disk on the wall outside the vault.

Figure A5. Kadji Sai. The entrance to the vault. Sasha Agishev, a KIS technician, is standing out in front. Note the pole next to the ladder, which contains the cable to the GPS antenna mounted on top.

Figure A7. Kadji Sai. Another attempt to photgraph the pier inside the vault.

Figure A8. Kadji Sai. Part of the installation crew, including (from left): Ruslan, Sasha Matix, Ilya, Anat Bek, and Dulat.

Figure A10. Kadji Sai. Another view of the DAS and disk mounted on the wall, with the power board resting on top. Sasha is finishing the power hookup.

Figure B7. Kadji Sai. At the entrance to Anat Bek's house, just before heading back to Bishkek. From Left: Ilya, Ruslan, Cholpon, Combat, Anat Bek, Kolya, and Steve.


Photos From the KaraKul Installation

Figure B7. Karakul. Training session for local operators. View is from the top of the steps leading down to the vault. The entrance to the vault is through the door at the bottom left. DAS, Disk, and Power board are sitting on a small table at the bottom of the steps with the Varta batteries in the front. The cables and break out box (above Ilya's head) are hung on the wall and pass though a hole in the wall near the break out box.

Figure A12. Karakul. View of the vault, looking approximately north. The GPS antenna has been placed under the roof near the top of the ladder. The entrance to the vault is through the door to the left of the ladder.

Figure A13. Karakul. Interior of the sensor vault. Ilya is standing in front of the CMG-40T sensor, beneath the small silver box.

Figure A14. Karakul. The CMG-40T sensor on the corner of the pier.

Figure A15. Karakul. Old and new technology at the Karakul station. I should note, however, that a week later the hard disk in the laptop died. No doubt the typewriter is still working.

Figure A16. Karakul. Post-installation party. Obligatory bottles of Vodka and Coke may be seen on the table.

Figure A17. Karakul.Another view of the party, just to prove I was there.


Photos From the Ananeva Installation

Figure A18. Ananeva.View of interior of vault, with CMG-40T beneath the silver box in the front of the picture.

Figure A19. Ananeva.Another view of interior of vault, with CMG-40T beneath the silver box in the rear of the picture. Note break out box hung on the wall. GPS cable is leading to a ventallation hole in the ceiling just above the pier.

Figure A20. Ananeva.DAS and disk located on the floor in the room just outsied the seismometer vault.

Figure A21. Ananeva.Entrance to the vault from the steps outside. Beyond the first door is the small room that houses the DAS and disk. Beyond the second door is the seismometer pier.

Figure A22. Ananeva.View of the vault from the outside, looking approximately north. The GPS antenna is located under this side of the roof about halfway back.

Figure A23. Ananeva.Shasha Matix constructing the pole for mounting the solar panels.

Figure A24. Ananeva.Solar panel pole erected and operational. View looking to the west.

Figure A25. Ananeva.Solar panel pole rising above the orchard. View looking to the north.

Figure B1. Ananeva. Ilya training Umet Bek in the fine points of RefTek maintenance.

Figure B3. Ananeva. The installation group at Ananeva, just before leaving for Karkul. From left: Umet's wife, Sasha, Ruslan, Kolya, Steve, and Umet.


Photos From the Kantau Installation

Figure B9. Khantau. View of the Kantau site, looking east. In the front is the GPS monument with the Trimble antenna on top, with the entrance to the seismic bunker and the solar panel pole behind. In the distance is the TV relay station.

Figure B10. Khantau. View of the Site, looking north-east. GPS monument to the left, entrance to bunker center, and solar panel/telemetry pole to the right.

Figure B11. Khantau. View from the site, looking south. This is a panorama series with the next photo.

Figure B13. Khantau. East of figure B11 above.

Figure B14. Khantau. Sasha Matix pulling the GPS cable through the solar panel pole. The GPS antenna is mounted just below the telemetry cable.

Figure B15. Khantau.Kolya starting dinner. Note the Russian version of the Primus stove to the lower left.

Figure B16. Khantau. Sunset with GPS monument.

Figure B17. Khantau. Steve peeling potatoes. Happy camper.

Figure B18. Khantau. General dinner preparation. Sasha is disecting the onions.

Figure B19. Khantau. Yet another perspective of the site.

Figure B20. Khantau.Ilya digging gravel to bank against the seimic bunker. This is what you go to graduate school for? Sure! See the next figure.

Figure B21. Khantau.Steve digging gravel to bank against the seimic bunker. Good thing I learned this from Molnar!


Photos From the Narin Installation

Figure B23. Narin.Taking a break for a pomedor and xleb lunch on the way to Narin. Medeer, the KIS technician, is standing at the rear.

Figure B24. Narin. Setting up at the site, near the entrance to the vault.

Figure B26. Narin. The CMG-40T on the pier in the vault.

Figure C1. Narin. Steve trying to look busy.

Figure C2. Narin. GPS antenna installation: a novel idea on how to construct a secure site -cover it with concrete!. The antenna was placed in a small wooden box, which was then covered by a thin layer of concrete.

Figure C3. Narin. Another view of the GPS installation procedure.

Figure C4. Narin. Final product, with contrete forms still in place. You structural geology types will notice the great angular unconformity between the bedding and the vault walls.

Figure C6. Narin. Installation of solar panels at the complex. Panels are fixed to brackets located on the roof of the yellow building. Wires connect the panels to the building behind, which contains spare wires to the vault.

Figure C7. Narin. A view of the entrance to the vault from the complex, looking approximately SW.

Figure C8. Narin. Another view (back side) of the solar panel installation.

Figure C19. Narin. The big group shot, taken just before heading back to Bishkek.


A few Photos From IVTAN

Figure C21. IVTAN. One of the guest houses. This happens to be the one I stayed in, and is located next door to Trapeznikov's place.

Figure B22. IVTAN. Interior of the guest house, showing the "office" with comfie chair.

Figure C22. IVTAN. Panoramic view behind (west) of the guest house. In this portion you can see the main part of the IVTAN administrative offices, the old stolovia, and the new sauna (the yellow building with the green roof to the left. Biskek is farther on in the fog.

Seismograms

The following are a few seismograms of a regional earthquake recorded the huddle test in the Stolovia prior to the deployment. These gif's were created using PQL X window screendump followed by XV.
Time series. Note high coherence and proper polarity.
