Strong Motion Data Release Policy
The IES operates some strong-motion networks in Taiwan. Data from these networks are processing and analysis for further scientific analysis. We provide the corrected strong motion data in ASCII for off-line access. You may use "Data Request Form" to determine what digital waveforms are available from the IES, and to generate and submit a request for data. A list of networks is brief description as follows:
(1) SMA1 (1973~ 1992)
(2) Strong Motion Array in Taiwan, Phase 1 (SMART1, 1980~1991)
(3) Strong Motion Array in Taiwan, Phase 2 (SMART2, 1990~ )
(4) Central Mountain Strong Motion Array (1993 ~ )
(5) Strong Motion Downhole Array in Taipei Basin (1993 ~ )
(6) Temporary Networks
1990 Hualien earthquake (ML=6.0)
1991 Tainan earthquake (ML=5.7)
1998 Rueyli earthquake (ML=6.2)
1999 Chichi earthquake (ML=7.3)
Lotung Large Scale Seismic Test (LLSST, 1985~1990)
Hualien Large Scale Seismic Test (HLSST, 1993~ )
[note]: as to the H LSST data, please contact with Taipower
(8) Seismicity (Taiwan Telemetered Seismographic Network, 1973~1992)
You can request the data in either event number or in year/month/date format for some specific networks.
What you can request?
At this time, you may not request any recent strong-motion data that had not gone through the quality control procedures. We hope to remove this restriction in the future.
When you use data from the IES, please provide a proper acknowledgement of the data source. And we'll greatly appreciate receiving one copy of your thesis, preprint, or reprint.
Please mail to
Dr. Win-Gee Huang
P.O. Box 1-55, Nankang,
Taipei 11529, Taiwan, R.O.C.
By the way, please do not release the data.
