Summary
Sea level is being used to provide a datum for monitoring vertical tectonic deformation in the Shumagin Islands Seismic Gap. An array of sea-level monitors has been installed that records filtered near-shore sea-level variations and in some cases, piezometric pressures on shorelines with a resolution of 1 mm of water height. The data from the sea- level monitors are transmitted via satellite to provide hourly values for analysis. The spacing between monitors is less than 30 km to enable deformation processes to be studied in detail. In the last two years, the islands have tilted to the south with an amplitude of approximately 10-6 radians/year.
