GPS/GNSS Analisis on Lombok Earthquakes: CO-SEISMIC DEFORMATION

Between July 28, 2018 until August 30, 2018, 5 significant earthquakes with M > 5.9 struckLombok Island (see Figure 1). Those earthquakes resulted surface deformation such as coseismic that caused change on geodetic control network coordinate. In order to maintenance coordinate of geodetic control network in Indonesian datum, so called Sistem ReferensiGeospasial Indonesia 2013, which the coordinates of SRGI2013 defined at epoch 2012.0, the deformation due to plate motion and earthquakes are estimated. The co-seismic deformation caused by the earthquake is used to updated the deformation model of SRGI2013. Badan Informasi Geospasial has already installed the continuous GNSS/GPS (cGPS) in the Indonesia region for geospatial reference system.
