We will do the basic data processing of all available strainmeter data in Taipei, Hsinchu and Chiayi areas, and also the follow-up abnormal strain analysis with its relationship to the possible major earthquake. We also use the permanent GPS station data of the Central Geological Survey, and some exchanged data from other organizations, to do the daily GPS strain analysis. Both borehole strain and GPS strain in the same region will be compared to each other, and find a best explaination of the possible strain behavior of that region. In addition, we will also select a specific area of major fault with significant crustal deformation to do the GPS strain analysis. Some permanent GPS staions will be selected to perform several triangles for long term strain variaions. The Longchuan fault will be selected for GPS strain analysis in this year project.GPS連續追蹤站井下應變儀CGPSBorehole StrainmeterGPS Strain
