| Abstract: | The bandwidth of JCZ-1T Ultra Broadband Seismometer covers whole observation band from high seismic frequency to solid tide. The observation condition to obtain stable low frequency data is suggested. The LP data from the vertical component and the horizontal component are processed to get the data of gravity and tilt solid tide. They are analyzed using Venedikov method. The data of a Indonesia large earthquake of Ms 8. 7 are processed, the PSD of Earth free oscillation is obtained. The instrument can take the integrated observation data of an earthquake event. |
