Crustal Movement of Thailand Disc Due to 28 March 2005 Earthquake as Observed from GPS Measurements.

要旨

The Nias earthquake on March 28, 2005 of the western coast of North Sumatra, Indonesia has resulted in crustal motions throughout SE Asia region. Crustal movement within Thailand is also expected from this earthquake. Fortunately, five permanent GPS stations in Thailand were operating during the earthquake event. This paper will analyze the GPS data obtained from the existing permanent GPS stations with GIPSY-OASISII software to show an impact of the Nias earthquake on the horizontal displacements of stations coordinates in Thailand. Results indicated that the earthquake has resulted in small horizontal displacements in the central and southern parts of Thailand.
