Coseismic displacements and inospheric changes of the 2013 M s7. 0 Lushan earthquake from GPS measurements

By inverting GPS data recorded at stations of the Crustal Movement Observation Network of China (CMONOC) near the 2013 Lushan Ms7. 0 earthquake, we found a horizontal displacement of 22mm at a site about 32km SW of the epicenter and vertical displacements of as much as 12. 4mm at several sites. The vertical displacements were generally uplift on the west side of the nearby Longmenshan fault zone and subsidence on the east side. We also found coseismic ionospheric disturbances about 0. 5 to 0. 9 TECU in amplitude that lasted for about one hour.
