Field experiments of seismometers

In order to understand the seismic waveforms and the seismic instruments, on 22 Jan 2021, we conducted our seismometer experiments near the PG Hall 2 (next to CWChu Colleage) in CUHK campus, close to the MTR railway.

Field experiments near the MTR railway

Before conducting the experiments, Prof. Yang introduced the two types of instruments, the strong motion accelerometer and the broad-band velocity seismometer. The we set the instruments on the ground surface and monitored the waveforms when the rail trains passing by.
