HKO monitors earthquakes using the Hong Kong Seismograph Network and analyses
the seismic data to determine parameters for earthquakes of local magnitude (ML) 1.5 or
above, within 200 km of the HKO Headquarters (latitude 22° 18’ N, longitude 114° 10’ E). The parameters are provided to various organisations, including Civil Engineering and
Development Department (CEDD), China Earthquake Administration, EAGP, ISC and the
Hong Kong University (HKU) on monthly or quarterly basis for reference. HKO maintains
a database of the seismic data, and provides the parameters and data to interested
organisations upon request.
