N2  - By using orthogonal regression method, a systematic comparison is made between body wave magnitudes determined by Institute of Geophysics of China Earthquake Administration (IGCEA) and National Earthquake Information Center of US Geological Survey (USGS/NEIC) on the basis of observation data from China and US seismograph networks between 1983 and 2004. The result of orthogonal regression shows no systematic error between body wave magnitude m sub-b determined by IGCEA and m sub-b (NEIC). Provided that m sub-b (NEIC) is taken as the benchmark, body wave magnitude determined by IGCEA is greater by 0.2-0.1 than the magnitude determined by NEIC for M=3.5-4.5 earthquakes; for M=5.0-5.5 earthquakes, there is no difference; and for M greater than or equal 6.0 earthquakes, it is smaller by no more than 0.2. This is consistent with the result of comparison by IDC (International Data Center).     <p>Language: en</p>
