Dear colleagues,

We are pleased to announce that the Taiwan Seismological and Geophysical Database Management System (GDMS) will be officially open to the world since Jan. 1, 2022. This web service platform archives both seismological and geophysical datasets that are mainly collected by the Taiwan Central Weather Bureau (CWB) in the past two decades. The official link of GDMS is at

CWB is running two major seismic networks, CWBSN and TSMIP, in the Taiwan region. CWBSN stations are equipped with various seismometers at different depths and the data after 2012 is open from GDMS. On the other hand, the TSMIP (Taiwan Strong Motion Instrumentation Program network) is composed of 700+ free-field strong motion stations. But currently only continuous TSMIP data collected after Dec. 2020 is open. In addition, Taiwan event catalog created by CWB since 1991, which is critical to several aspects of application of seismology and risk analysis, is also accessible from GDMS.

The GNSS, groundwater level (GW) and geomagnetic (MAGNET) datasets recorded by the Taiwan Geophysical Network for Seismology (TGNS) since 2007 can be downloaded from GDMS as well. Two contributed GNSS datasets by National Dong-Hwa University and the Institute of Earth Sciences, Academia Sinica (IESAS), Taiwan is also open together with the CWB GNSS dataset.

This GDMS platform is a joint work with the IESAS and the Taiwan Earthquake Research Center (TEC). If you find this platform helpful, please consider to cite the GDMS with DOI offered by FDSN:

We wish you a very Happy New Year!
