In an effort to advance seismic research and enhance urban disaster prevention in the Greater Taipei Area, Taipei Financial Center Corporation (TAIPEI 101) and the Institute of Earth Sciences (IES) at Academia Sinica officially entered into a milestone seismic observation cooperation agreement on May 1, 2010. This collaboration seamlessly integrates cutting-edge earth science with one of the world's most iconic structural landmarks.

​

Expected results:

1. The simultaneous deployment of broadband seismometers, rotational seismometers, and GNSS (Global Navigation Satellite System) within the TAIPEI 101 infrastructure represents a cutting-edge, multidisciplinary observatory.

2. By blending advanced geophysics with structural health monitoring (SHM), this integrated network is expected to yield several milestone scientific achievements.

3. Traditional seismic monitoring is limited to three translational axes (North-South, East-West, and Vertical). However, ultra-tall buildings undergo complex twisting (torsion) and rocking motions during earthquakes or strong wind events

4. Seismometers excel at capturing high-frequency, dynamic vibrations but lose accuracy when measuring permanent displacements or slow, long-period sways. Conversely, high-frequency GNSS provides high-precision, absolute spatial positioning but lacks sensitivity to subtle high-frequency shaking.

5. Analyzing structural torsional responses has been limited to numerical studies due to the rare deployment of translational and rotational sensors in buildings. By leveraging new sensor data and innovative signal processing, researchers can capture real-world rotational dynamics, offering vital new perspectives to refine earthquake engineering and seismic structural health monitoring.
