Response of Antarctic tide gauge stations to global earthquake-caused tsunamis
-
Abstract
The existing research on Antarctic tides mainly focuses on sea level changes, elevation conversion, and conventional harmonic analysis. The analysis of sea level anomalies at Antarctic tide gauge stations is still rare. This article focuses on the sea level anomalies in the data of Antarctic tide gauge stations, extracts global earthquake-caused tsunami events reaching Antarctica, and analyses the responding capabilities of different stations in Antarctica to global earthquake-caused tsunami events. This article first uses tide harmonic analysis to remove the trend items in the sea level data, analyses the larger sea level anomaly signals in the residual water level, and then compares different methods and selects 2.5 times of the standard deviation to extract the global earthquake-caused tsunami events reaching Antarctica. After picking up the sea level anomaly points, this article compares the relationship between the different tide-gauge-stations' responses to earthquake-caused tsunami events and their locations. It is concluded that the tide gauge stations in the Wilkes Land of East Antarctica and the Antarctic Peninsula and its nearby islands are more responsive. Eight stations including the Great Wall Station are suitable for responding and recording of global earthquake-caused tsunami events.
