Abstract
The 2019 July 7th North Maluku earthquake with M7.0 occurred in the Sangihe double subduction zone. The earthquake epicenter is located at latitude 0.54 N and longitude 126.19 E. Here, we employ continuous Global Positioning System (cGPS) observations to estimate coseismic deformation associated with the North Maluku earthquake. Using 6 days cGPS observations before the event and 6 days cGPS observations after the event we estimate coseismic deformation at 4 nearest cCGPS stations. The coseismic deformation for CTER (Ternate) cGPS stations which located about 134.80 km from epicenter is about 8.4 mm to north-west direction, while the coseismic deformation for CBIT (Bitung) cGPS station (about 151.68 km from epicenter) is 8.3 mm to the south-east direction. Coseismic deformation for another two cGPS stations (CTBL/Tobelo and CTHN/Tahuna) are about 3.0 - 3.6 mm. This value is very important to maintenance the Indonesian geodetic control network in Indonesia and earthquake studies in Indonesia.
