Abstract
We installed three continuous GPS stations on Mindanao Island to provide a basis for enhancing the monitoring of crustal movements. Because there are frequent power outages and Internet connections are slow and unstable in this region, the data acquisition had to be improved by taking necessary hardware and software measures. The cGPS observations have revealed displacements related to plate motions, creep of the Philippine Fault, and a large earthquake. Evaluation of detectability of interplate slip has indicated that our cGPS stations have enhanced the monitoring capability advance from Mw7.2 to Mw6.5 on the coast of northeastern Mindanao.
