This project tried to install 3 sets of magnetometers at the geomagnetic observatories along the Silk road where modern instruments for magnetic measurement have not yet installed. We put 3 sets of magnetometers at Inikli Turkey, Tbilishi (Dusheti) in Georgea and Alibag, India. We also set up real-time data transfer system through the Internet for Inikli and Alibag stations. With the data obtained by the magnetometers, we found that geomagnetic oscillations are generated at a total eclipse on March 29, 2006 which occurred in Africa - Middle-East area probably through the acoustic resonance between ground and ionosphere. The data are also used for a comparative study of geomagnetic pulsations by using both the data from the array and satellite. The data plots from Inikli station are, for example, already open from a web page,.http://kagi.coe21.kyoto-u.ac.jp/iznik/.

该项目试图在丝绸之路沿着尚未安装现代磁力测量仪器的地磁台安装3套磁力仪。我们将3套磁力计放置在土耳其的Tbikli，Georgea的Tbilishi（Dusheti）和印度的Alibag。我们还通过互联网为Alkkli和Alibag站建立了实时数据传输系统。利用地磁仪观测资料，发现2006年3月29日发生在非洲-中东地区的日全食时，地磁振荡可能是通过地面与电离层的声共振产生的。这些数据还用于通过使用阵列和卫星的数据对地磁脉动进行比较研究。例如，来自Zakkli站的数据图已经从网页. http://kagi.coe21.kyoto-u.ac.jp/iznik/上打开。
