Photos From the Wuqia Installation


Figure C19. Wuqia. Guo Biao (a.k.a. Mr. Sleepy) installing the solar panels to the roof of the observatory. We tied the rebars to the chimney to counter reported high winds. View to the north with Tien Shan in background.

Figure C20. Wuqia. Strange bird in bamboo tree. Actually, this is Xu Yi, trying to inspect our work on the roof of the observatory. This position earned him the moniker "big bird".

Figure C21. Wuqia. Hired help from Wuqia village digging a hole for the sensor in the northeast corner of the observatory compound.

Figure C22. Wuqia. Guralp CMG-3ESP placed on a cemented tile at the bottom of the hole. Depth is slightly more than a meter. No bedrock here, just a lot of cobbles.

Figure C23. Wuqia. As figure C22 (above) with our nice insulated box over the top of the sensor.

Figure C24. Wuqia. Filling in the hole. Xu Yi working hard (note expression) and Chun Jo Hue supervising.

Figure C25. Wuqia. Setting up the DAS in the observtory with the Palmtop. Wires go though hole in bottom of window frame to sensor, solar panels, and GPS clock. Guo Biao doing the honors.

Figure C26. Wuqia. The setup of the recording system in the observatory, looking to the east with morning sun streaming in. Sensor is located just outside and to the left.

Figure D1. Wuqia. The observatory, looking west. The sensor is located in the right front corner within the walls. The solar panels are just visible on the roof. The next six pictures (D1 - D6) are a panorama of the site going progressively to the right (south).
