(3) The Northridge Earthquake (surface wave magnitude 6.6) struck the San Fernando Valley on January 17, 04:31 AM Pacific Standard Time, 12:31 UT. JPL1 and PVEP were displaced during the earthquake. We circulated two memos on the earthquake (IGS mails 453&457). Below are the coseismic displacements at JPL1 and PVEP based on an analysis of data from GPS Weeks 0730-0732. The displacements at JPLM: North: -4.5 mm +- 3.1 mm East: 6.3 mm +- 3.9 mm Up: -6.4 mm +- 4.9 mm The displacements at PVEP: North: 10.2 mm +- 3.1 mm East: 0.1 mm +- 3.8 mm Up: -3.2 mm +- 4.8 mm For the baseline length JPLM => PVEP: Before the earthquake: 54470.2180 +- 0.0018 m After the earthquake: 54470.2065 +- 0.0027 m The coseismic baseline length displacement: 11.5 mm +- 3.2 mm
